THE_URL:http://www.zenez.com/cgi-bin/scoprogfaq/faq?_recurse=1 THE_TITLE:SCO comp.unix.sco.programmer FAQ. (Category) SCO comp.unix.sco.programmer FAQ. This services tries to provide answers to the Frequently Asked Questions in news:comp.unix.sco.programmer. A backup of the most important files are on. ftp://ftp.lerctr.org/pub/zenez/ Thanks to Larry Rosenman ler@lerctr.org Since it is based on traffic in that group, it has a definite slant toward the SCO (Caldera) UNIX/OpenDesktop/OpenServer product families. However coverage is given to the UnixWare 7(OpenUNIX 8)/OpenServer 6 and OpenServer Development Kit (UDK) as well. It doesn't try to cover the same ground as the existing FAQs such as The comp.sco.misc FAQ http://aplawrence.com/SCOFAQ/ The comp.unix.programmer FAQ http://www.erlenstar.demon.co.uk/unix/faq_toc.html.

I don't have a compiler. What are my options? If you really want to be able to compile anything, buy the SCO Development system. That version (and earlier) of SCO UNIX did not come with the needed libraries or headers to allow use of third party compilers. While some people on the net have put together packages to allow you to compile minimal programs, there are still lots of problems in the area of networking and X that remain unresolved. Before you buy the compilers for this old version of the OS, you should probably consider the upgrade to OpenServer. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : I have a 3.2v4 OS and the SCO 3.2v4 DS. I'm trying to build something and seem to be missing headers and libraries. In that version of the OS, the TCP/IP and NFS development systems were not included in the DS, but were bundled as separate packages. You have to either get the "TCP/IP Development Kit" and the "NFS Develoment" kit or consider the upgrade paths mentioned above. These will give you, for example, libsocket. robertlipe@usa.net There were always bundled DS's (ODT DS) corresponding to the same-time-release Unix, TCP, NFS, etc. DS's. Unfortunately, packaging was such that if you had standalone Unix + TCP, you needed standalone Unix DS, TCP DS. Couldn't use Unix + ODT DS, nor ODT + Unix DS (though the latter might actually have worked, I forget). So if you're trying to buy a DS now, you need to be aware of the many opportunities to buy the wrong thing. From Bela Lubkin, minor editing by robertl robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : I have an OpenServer based system. I don't have a compiler. What are my options? If you're using Free OpenServer and comply with the licensing requirements, install the Free OpenServer compiler from the same CD. You cannot install the Free OpenServer compiler on a commercially licensed OpenServer. SCO's OpenServer Development system is available as a commercially supported product and includes two compilers, debuggers, and tools such as the custom distribution mastering toolkit. For more information, see http://www.sco.com/developer/products.htm. The SCO part number for SCO OpenServer Development System (media and license) is SA105-UX74-5.0. OpenServer includes all the necessary libraries, headers, man pages, and the linker to allow the user of third party develoment systems. One such system is the GNU Development System that's available on the Skunkware CD or the newer version available on Robert Lipe's home page and mirrored on SCO's Web site. This kit includes make, the assemblers, the debuggers, and everything you need for a functional development environment. This kit is available at ftp://ftp.zenez.com/pub/zenez/gcc and has documentation at ftp://ftp.zenez.com/pub/zenez/gcc/sco_ds.html and a little FAQ of its own (that should ultimately be smooshed into this one) at ftp://ftp.zenez.com/pub/zenez/gcc/gds_faq.html . robertlipe@usa.net See also http://www.sco.com/developers/products/devkits.html. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : I tried to build GCC on OpenServer 5 and it burst into flames. It is time to start using newer version of gcc. Take a look at ftp://ftp2.caldera.com/pub/ This is left for historical purposes. The first FSF release of GCC to include the necessary support to host or target OpenServer was 2.8.0. EGCS has supported OpenServer 5 since the epoch. Anything before this requires a patched version of GCC. Robert Lipe did the port of the GNU tools that appears on the Skunkware '96 CD and on ftp://ftp2.caldera.com/pub/Skunk96 or the old site ftp://ftp.sco.com . It is not a simple matter of 'configure ; make install'. It's a complicated product to build and unless you're planning to slog around in compiler internals, you really want to use the available binary kits. It is time that you start using a newer gcc. Please see ftp://ftp2.caldera.com/pub/skunkware . This is also mirrored on ftp://ftp.sco.com/skunkware . It is required that you install the necessary libraries and headers as described in the documention for that package that is in the "sco_ds.html" file at those URLs. The major contributors of the OpenServer code in GCC (Kean Johnston and Robert Lipe) are active members of the EGCS development team. EGCS is an enhanced GNU compiler system. EGCS contains complete support for OpenServer 5 in both COFF and ELF modes and has received much attention and testing. See http://gcc.gnu.org for more details. GCC does include support for 3.2v4.2 and earlier SCO releases, though it requires the SCO development system be installed. EGCS also includes support for UnixWare 7 and for UDK. robertlipe@usa.net, gerberb@zenez.com GCC 2.8.0, released in 01/98, almost has functioning support for the OpenServer family of products. There is another entry in this FAQ that contains the necessary directions to circumvent the problem. robertlipe@usa.net In recent years, GCC 2.95.3 has packaged and supported for OSR5 (and UW7 as well). No GCC 3.x is as of yet provided by SCO. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Issues with GDB on OpenServer and UnixWare. OpenServer 5 support in GDB was sneaked into GDB 4.16 at the last minute and suffered from some problems. You must run configure --target=i486-unknown-sco3.2v5.0.0elf' to get a gdb that recognizes both COFF and ELF. Generally, you'll be better off using a GDB from Skunkware or building a newer version. 4.17 and 4.18 seem to work well. robertlipe@usa.net GDB 4.17 works well on OpenServer. robertlipe@usa.net GDB 4.18 seems to work OK for OpenServer. For UnixWare 7, you must either configure --target=i686-UnixWare7-sysv42mp or apply a minor patch to configure.tgt. robertlipe@usa.net If you are using gdb (or the native debugger) on Openserver and you get warnings of the form "no debugging symbols" on an ELF executable even though you are sure you gave specified -g on the object and executable build lines make sure that *all* the objects ( and libraries) going into the executable are also ELF format. The devsys will make ELF executables if any of the incoming objects are ELF. Any COFF files are converted to ELF format in passing but in the process symbol and debug information is removed from the resulting executable. All COFF objects -> COFF executable with symbol info All ELF objects -> ELF executable with symbol info Mixed ELF/COFF objects -> ELF executable - symbol info stripped. hops@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : How can I build XENIX or DOS binaries on my OpenServer system? By purchasing the "Xenix/DOS Cross Development Supplement". The SCO part number for the media and license is SA575-UX72-5.0. This gives you the Microsoft based tools that comprised the earlier development systems repackaged to work on OpenServer. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Can I generate binaries that run on older sysem on OpenServer? Yes, if you constrain yourself to use only features that existed in the older versions. For example, you can't use mmap(S) (A feature new in OpenServer) and expect it to work on older versions. You should also read the man page for cc(CP) for related issues. There are some bugs in the handling of POSIX terminal handling that affect this ability. #FIXME# more details. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Will ELF binaries compiled on OpenServer run on anything else? If compiled with the "UnixWare/OpenServer Development Kit" (UDK), binaries can run on any current SCO operating system. These tools can be hosted on OpenServer, UnixWare 2, or UnixWare 7. Binaries compiled with those tools that use no non-conforming facilities can run on any of these systems. Linux and the BSD familes can run many OpenServer and UnixWare binaries via their ibcs2 support. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Link errors on functions like gethostbyaddr, gethostbyname For the unresolved functions, do a 'man functionname'. For example, a 'man gethostbyaddr' shows gethostbyname(SLIB) ******************* ____________________________________________________________________________ gethostbyname, gethostbyaddr, sethostent, endhostent, herror, hstrerror -- get network host entry gethostbyname- get network host entry by name gethostbyaddr- get network host entry by address [ ... ] Syntax ====== cc . . . -lsocket #include <netdb.h> This man page tells us that we must #include <netdb.h> before using these functions and that we must be sure that our cc line links against the socket library by having a '-lsocket' at the end. This same technique should be applied to any link error that you feel the system really does know about but you just don't know where it is. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : How do I read or traverse directories within a program? ftw(S) will traverse and recurse a path, calling a function of your creation on each object found. If you just want to open a directory and read it, you must use the functions described in directory(S) such as opendir(S) and readdir(S). In OpenServer, you can no longer read directories like a file. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : How can I detect null references in my program? On OpenServer, there are two kernel global variables of interest in /etc/conf/pack.d/kernel/space.c that may be set. If notice_null_refs is non-zero, a kernel message will be generated when a program attempts to reference the page with a virtual address of zero. If signal_null_refs is non-zero, the kernel will detect zero page references and deliver a signal to the process, killing it and likely leaving a core dump for analysis. TLS594, available at ftp://ftp.sco.com/TLS allows finer control of these actions. robertlipe@usa.net On UnixWare 7, the 'nullptr' command can enable, disable, or trap null pointer references on a per-uid basis. On UW7 before 7.1.0, many system utilities (vi, more, pg) become unstable if nullptr disable is ineffect. robertlipe@usa.net With UW7.1, the MALLOC_CHECKS environment variable can be set to cause page zero to be unreadable. See malloc(3C). This works on a per-process basis. Note that since page zero must first be read to turn off access, when "nullptr disable" has been set, this MALLOC_CHECKS setting will cause a process to die when it first gets into malloc() code. dfp@sco.com Beginning with UnixWare 7.1.3 see also memtool(1) for dealing with null pointers and related memory bug checks. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Where is alloca()? Add -lPW to your link line to get alloca() robertlipe@usa.net Note that for UDK C++, alloca() is not supported. (This is because it is incompatible with an efficient exception handling implementation. Note that better alternatives to alloca() exist in C++, such as the vector class in the draft standard library or the Block class in UDK Standard Components.) jls@sco.com If you really need an alloca() to build something and are willing to live with the above and can't find one anywhere else many of the gnu software sources include one. bash-1.14.6/lib/malloc/alloca.c bash-1.14.6/lib/malloclib/alloca.c bash-2.0/lib/malloc/alloca.c diff-2.6/alloca.c diffutils-2.7/alloca.c fileutils-3.16/lib/alloca.o find-3.6/lib/alloca.c findutils-4.1/lib/alloca.c gawk/gawk-3.0.3/alloca.c make-3.75/alloca readline/alloca.c sed-2.05/alloca.c tar-1.12/lib/alloca.c hops@sco.com Heres an asm version (from lxrun) alloca.s .text .globl alloca .align 4 alloca: popl %edx / return address popl %eax / nbytes movl %esp,%ecx subl %eax,%esp / calculate new esp andl $-4,%esp / make sure stack is 4 byte aligned movl %esp,%eax / return pointer to new memory in eax pushl 8(%ecx) / copy saved registers pushl 4(%ecx) pushl 0(%ecx) pushl %ecx / we need to push a fake argument here / since alloca's caller will attempt to / clean up the stack jmp *%edx / return It'll build on Osr5 and UW7 with a simple Makefile rule referring to alloca.o hops@sco.com In the UDK and in UW7, there is an intrinsic version of alloca() built into the compiler. It is enabled via -Kalloca. dfp@sco.com The UDK C++ compiler does now support -Kalloca as well. I think this change was made as of UW 7.1.0 or thereabouts. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Purify or other malloc checkers. On Jan 19, 1996, Larry Phelps said: I know of two such products for SCO Unix these: Insure++: Parasoft Corporation 2031 South Myrtle Avenue Monrovia, CA 91016 Phone: (818) 305-0041 Fax: (818) 305-9048 Email: insure@parasoft.com HTTP: http://www.parasoft.com Sentinel: AIB Software Corporation 1145 Herndon Parkway Herndon, Virginia 22070 Phone: (703) 787-7700 Fax: (703) 787-7720 Email: info@aib.com HTTP: http://www.aib.com robertlipe@usa.net checkergcc exists for linux. Could probably be ported to SCO systems. robertlipe@usa.net For C++, the UnixWare 2.x and UDK Standard Components has a memory checking tool called 'fs'. It's not as powerful or transparent as commercial tools such as Purify, but it's better than nothing. jls@sco.com On UnixWare 7 and on UDK, the standard malloc library has instrumentation that can be turned on at runtime. If you export MALLOC_CHECKS, you can control the tests that are performed on the heap. UnixWare 7.1.0 has even more instrumentation and can deliver a SIGSEGV (conveniently trapping you into a debugger) at the bus cycle that delivers the bounds exception. robertlipe@usa.net Electric Fence from Bruce Parens works just fine on OpenServer. I don't really know that it offers anything above the MALLOC_CHECKS tests in the system libraries. robertlipe@usa.net dmalloc (www.dmalloc.com) works fine with OSR5. john@kuwait.net Beginning with UnixWare 7.1.3 there is the "memtool" tool, which does a lot of the memory error detection work that commercial tools like Purify do. See http://uw713doc.sco.com/en/man/html.1/memtool.1.html or the memtool(1) man page on your system. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : How can I read kernel data through /dev/kmem in a user program? This can be a powerful technique, but it is also horribly non-portable. Kernel data structures can and do change between releases, so your program may break. The basic idea is to call nlist(S) with the table of kernel symbols you wish to examine. nlist will then fill in the addresses of those symbols. You can then open /dev/kmem, use the addresses to lseek(), then issue a read(). On systems that have mmap() available, this is a good use for it. You can look at the sources of programs like u386mon for examples of how to do this. An OpenServer-specific extension is the tab(HW) driver. See that man page and string(HW), and look in /dev/table and /dev/string to see how it works. This only works for a small fixed subset of kernel data. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : How to detect SCO product or version at compile time? Ordinarily, this is a bad idea. Rather than basing your code on "am I on OpenServer or not?", you're typically more interested in, say, "do I have mmap(S) or not?" Programs like GNU autoconf provide a powerful way to test for features. The SCO provided compilers and the GCC's that are truly OpenServer-aware all provide a manifest "_SCO_DS" that is set to one when targeting SCO OpenServer. robertlipe@usa.net That having been said heres some code that attempts to detect the various SCO platforms upto and including Gemini - It will probably report UDK on Osr5 and UW as Gemini I. #include <stdio.h> main() { #if defined(_SCO_DS) printf("OpenServer\n"); #elif defined(__UNIXWARE__) printf("UnixWare gcc\n"); #elif defined(__USLC__) #if defined( __STDC_VERSION__ ) && __STDC_VERSION__ == 199409 printf("Gemini I cc\n"); #else printf("UnixWare cc\n"); #endif #elif defined(M_UNIX) printf("ODT 3 or earlier\n"); #else printf("Other platform\n"); #endif } hops@sco.com Heres a slight update that understands UW7 CC #include <stdio.h> main() { #if defined(_SCO_DS) printf("OpenServer\n"); #elif defined(__UNIXWARE__) printf("UnixWare gcc\n"); #elif defined(__USLC__) # if defined( __STDC_VERSION__ ) && __STDC_VERSION__ == 199409 printf("Gemini I cc (UW7 and UDK)\n"); # else # if defined(__SCO_VERSION__) printf("Gemini I CC (UW7 and UDK)\n"); # else printf("UnixWare cc\n"); # endif /* SCO_VERSION */ # endif /* STDC_VERSION */ #elif defined(M_UNIX) printf("ODT 3 or earlier\n"); #else printf("Other platform\n"); #endif /* uw7 ccs */ #if defined(__SCO_VERSION__) printf("__SCO_VERSION__ is %ld\n", __SCO_VERSION__); #endif } hops@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : How to write dialers look at ecu, XC robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : POSIX Timers mkdev suds.

In this case the solution is to give the option CC +.cc ... Note that more recent OpenServer CC commands do accept .cc and other common suffixes, as do the UnixWare 2.x and UDK CC commands. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Which C compiler delivers the best performance? There are at least four popular compilers on SCO OpenServer and two for UnixWare. 1) /bin/cc is based on the USL cc, not the Microsoft cc that shipped with earlier SCO products. This is actually a respectable compiler. It generates very good code, has a reliable optimizer, and is pretty quick and solid. You can control optimizations with the -O flags and can fine tune the optimizations with the -K options. 2) icc ships with the SCO DS and is based on the Intel Reference Compiler. This compiler can generate amazing code and very good warnings and diagnostics about your source. It can generate Pentium Pro specific optimizations. The price you pay for all this optimization is high in terms of compile time. It can be slow to build your program. 3) gcc is part of the GNU ds. It generates code that is comparable to the quality of the /bin/cc output. The warnings and diagnostics are good. Optimizations can be controlled via the -O, -m, and -f flags. 4) UDK compiler. See the below for more information on the developement kits available for SCO OS's. http://www.sco.com/developers/products/devkits.html All three compilers are ANSI C by default, with options to fall back to K&R. If you're looking for a "magic bullet" from the compiler to speed up your program by an order of magnitude, just by using a different one or by wiggling some compiler switches, don't. Only after you've highly tuned your algorithms and implementation should you even worry about compiler performance. Even then, you should be prepared to stare at the compiler output and run extensive tests before making an informed decision. robertlipe@usa.net, gerberb@zenez.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : POSIX threads or threads for Unixware and/or OpenServer 5.0.X and ODT 3.0? Unixware has UI (UNIX International) threads. UnixWare 7.0.1 and higher support POSIX (P1003.1c) threads.

Use a good port of GCC 2.5.X gerberb@zenez.com, robertlipe@usa.net OpenServer 5.0.7 mp3/up3/supp3 has a UDK libthread.so.1 threads library. This can be used to write threaded applications using the UDK development tools. It contains both POSIX and UI API interfaces. This is still a user-space threads library (because OSR5 has no kernel threads); it is a version of the UnixWare 7 libthread, modified to operate under the assumption that the number of available LWPs is always one (which is the case with no kernel threads). Thus, you will see no performance benefit from using this threads library on MP systems. However, it does have better asynch I/O and libc synchronization than other OSR5 third-party user-space libraries (FSU, Pth) and so is recommended for use in UDK-based applications. The Java 1.4.2 implementation on OSR5 mp3/up3/supp3 also uses this new UDK libthread. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Where to get STL for SCO C++? Here's the modern answer. Beginning with the UDK 7.1.1b release in Nov 2000, a full and high-quality implementation the entire C++ Standard Library, including all of STL, has been available as part of the SCO UDK product for both UnixWare 7 and OpenServer 5. There is no need to look anywhere else for STL. The sections that follow are for historical interest only, or perhaps for people on very old versions of OSR5 or UW7. jls@sco.com Here's the short answer. STL is not part of the UDK yet, but we're working on it. In the meantime, use the good freeware STL from Silicon Graphics. A packaged version of SGI STL 3.11, adapted for use with the UDK C++ compiler, is on Skunkware at http://www.sco.com/skunkware/devtools/index.htm#stl . See the README.SCO inside there for a description of how to use it. jls@sco.com Here's the long answer. There are four commercial sources for the Standard Template Library: Modena, ( modena@netcom.com ) Rogue Wave ( http://www.roguewave.com ), Dinkumware ( http://www.dinkumware.com ) and ObjectSpace (http://www.objectspace.com/toolkits/ ). These vendors generally sell the STL either on an OEM basis to compiler vendors , or as part of large site licenses. In other words, it's hard to get a single user license, especially for SCO platforms. There is also an up-to-date, public domain version of STL: Silicon Graphics ( http://www.sgi.com/Technology/STL ) This is the best bet for using on SCO platforms. We have a packaged version of it for UDK C++; see the "short answer" above. Note: As of July 1997, the ObjectSpace STL is now also available free for commercial use. However the ObjectSpace download page only offers it in package d form and for only a few platforms. The Solaris 2.5 and Windows 95 versions have been downloaded and unpacked but they are tailored for the compilers on those platforms and efforts to build them show that it would be a lot of work to get them to compile with the UDK C++ compiler (partly because every C++ compiler supports different new features right now, and partly because the auto-configuration tool they use is not included in these distributions). I can't unpack their MIPS/Irix version, which is the only one compiled against an EDG-based compiler, because their install tool is an executable program. ObjectSpace has told me in e-mail that they have no plans to distribute a source code only, configuration-tool-included version of their STL, so I can't be too hopeful of making use of it on SCO platforms In addition, versions 2.6.2 and later of libg++ (the GNU C++ library) include a t least a part of the STL that works with GNU C++. However as of egcs libg++ has been trashed and has been replaced by the SGI version. There is also the original public domain version from Hewlett-Packard that is still available, but it is inferior to the current one from SGI, from which it is based. (Alex Stepanov, the inventor of STL, now works for SGI.) OpenServer and UnixWare 2.x C++ The native OpenServer 5.0 C++ compiler is Cfront-based, and thus will have an impossible time compiling most STLs. At one time, ObjectSpace said that their STL had been specially modified to compile with Cfront, in which case OSR5 C++ should work. Don't know if this is still the case. We have not recently tested any of the STLs against the native UnixWare 2.0 or 2.1 C++ compilers. At one time they all could build, but the STL code may now be assumi ng more advanced compiler features. In both cases, you're *much* better off moving to the UDK, because it supports many more of the advanced template features that STL relies upon and takes advantage of. robertlipe@usa.net, hops@sco.com, jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : Software packaging and distribution options for OpenServer & earlier releases My advice, at this point, is "just say no" to CDMT.

They're not going to be supported in UnixWare 7, and they're not supported by the OS versions prior to OpenServer. Walk away while you can. I would be remiss to not point out the widespread public opinion that SSO's, custom+, cdmt, and the rest of this way of life are, uh, not going to win any popularity contests.

Most of these were actually intended to be in 5.0.0, but weren't ready in time. Kernel support for all of them is already present in 5.0.0, so programs compiled in 5.0.4 would work on 5.0.0, except that there are potential shared library issues. Of the new functions in 5.0.4, only four of them represent new entry points in the shared libraries. These are fattach(), fdetach(), makecontext(), and mkstemp(). As long as you don't call any of those, I can think of no reason that your programs compiled on 5.0.4 would not work on 5.0.0/5.0.2. If you *do* call any of those functions, your programs will only work if you avoid calling the dynamic shared object versions of the functions. There are three ways to do so: 1. Compile COFF binaries (the default compilation mode). Advantages: if you stick to the right subset of system calls, COFF binaries will work on SCO Unix 3.2v4.2 and earlier; also, statically links in functions which will work on 5.0.0/5.0.2 kernels, but which are not in the shared objects on those systems. Disadvantage: binaries much larger. 2. Compile static ELF binaries (`cc -belf -dn`). Advantage: statically links in functions which will work on 5.0.0/5.0.2 kernels, but which are not in the shared objects on those systems. Disadvantage: binaries much larger. 3. Compile dynamic ELF binaries (`cc -belf`), but statically link in those functions. Technique: $ mkdir /tmp/newlib $ cd /tmp/newlib $ ar xv /usr/lib/libc.a fattach.o fdetach.o makectxt.o mktemp.o $ ar rv libstatic-stuff.a *.o $ mv libstatic-stuff.a /local/lib ... $ cc -belf foo.o bar.o -L/local/lib -lstatic-stuff -o foo Advantage: preserves binary size advantage (and cross-OS- compatibility) of dynamic ELF, while avoiding symbols that won't resolve on 5.0.0/5.0.2.

I'm building a static library and the link errors seem to reference things from the STL that were used in the library - what gives ? One possibility is that the necessary instantiations weren't done when you formed your library. Try using the "CC -Tprelink_objects" command on the .o's that go into the library, before doing the "ar" step that forms its archive. Like this: CC -c a.C b.C c.C CC -Tprelink_objects a.o b.o c.o ar rv libfoo.a a.o b.o c.o I can't be sure this will solve your problem but it's the first thing to try. Diagnostics coming out of STL are legendary for being hard to understand ... hops@sco.com The above CC -Tprelink_objects step is generally necessary when preparing an archive that contains internal template instantiations. There is a known problem in doing this. If multiple archives are being linked against, it is quite possible that you will get multiple definition errors coming from common template instantiations occurring in multiple .o files. We are currently working on a solution for this problem in our next release. For work-arounds, you either have to restructure your source files, or build with CC -Tlocal (which will blow up object sizes significantly). jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : C++: I'm building C++ source with the UDK and I get warnings about 'omission of explicit type is nonstandard ("int" assumed)' The error is that "implicit int" is no longer allowed in C++.

As of the UDK 7.1.1b release in Nov 2000, a full high-quality threads-safe supported version of the entire ANSI/ISO C++ Standard Library is available as part of the UDK development kit for UnixWare 7 and OpenServer 5. There is no need to look anywhere else. The entries below are for historical interest only or possibly for people using really old versions of UW7 or OSR5. jls@sco.com The UDK C++ compiler does not yet contain a full implementation of the draft ANSI/ISO C++ Standard library. In addition to the Standard Template Library (STL), which is covered by a separate FAQ entry, the new standard library includes: * language support and diagnostic classes * new, templatized versions of the iostreams and complex classes that were in the old de facto AT&T standard library * a number of new facilities, such as strings, locales, and valarrays (for Fortran-wannabe numeric computation). The current SCO UDK C++ fully implements the language support and diagnostic classes (clauses 18 and 19 of the draft standard). The current SCO UDK C++ does not implement the new standard versions of the iostreams and complex classes, but rather still contains the old non-templatized versions, slightly updated for new types such as bool. The current SCO UDK C++ does not implement any of the new facilities. Three commercial STL vendors -- Modena, Rogue Wave, and Dinkumware -- also market full standard library implementations, but on an OEM or large site basis, that is generally not available for SCO platforms. There are free implementations of the following parts of the library. (If these links get out of date, try consulting the comp.std.c++ FAQ at http://reality.sgi.com/employees/austern_mti/std-c++/faq.html#C6 for where to get them from.) string A partial implementation of the string class is available that Modena wrote; it is at http://aw.com/cp/musser-saini-source.html . The file bstring.h in it needs one change to compile under UDK C++: change the #ifndef __BOOL_DEFINED on line 36 to #ifndef _BOOL The ObjectSpace free STL distribution also includes a string implementation, but building it has the same problems as building their STL (see above). valarray A partial implementation of valarray is available that Daveed Vandevoorde wrote; it is at ftp://ftp.cs.rpi.edu/pub/vandevod/Valarray . The Rel2_0Beta2 version there needs one change to compile with the UDK C++ compiler: add the lines #ifdef __USLC__ /* SCO UDK C++ */ # define COMPILER_RECOGNIZED #endif at line 43 of file valplat.h. jls@sco.com EGCS, the Enhanced GNU Compilation System includes the SGI implementation of STL and the necessary modifications to make it work with EGCS.

SCO now has many Gnu binaries available. Skunkware is available at ftp://ftp2.sco.com/pub/ The Below is for historical purposes. ---------------------OLD---------------------------------------------- ------ Now that GDS looks like it's getting dusty, and there are shiny new releases on ftp://ftp2.caldera.com/pub . Please start using the newer GCC. GCC Advantages relative to GDS GCC contains newer optimizations and can generate hotter code for some input. GCC is a much newer G++ base and much more closely reflects the state of a useful C++ implementation. This below is left for historical purposes. GDS as found on ftp://ftp2.caldera.com/pub/Skunk96 It's prebuilt and custom installable, so anyone can make it go with very little effort. It's self-contained and absolutely works well without the native DS. Assemblers, debuggers, and all that stuff are all there and they just work. It has much air-time - it's on probably thousands of machines around the planet and robertl has almost a dozen postcards to prove it. :-) Disadvantages of GDS relative to either EGCS or GCC. It's based on the 2.7-ish GCC which does have some problems on x86 targets with higher optimization levels. However, many people have compiled many megabytes of code and never encountered any of these problems. It's based on the 2.7-ish GCC which means that it reflects the level of C++ that was implemented in GCC at that time. It certainly does not track the standards as they exist in '98 very well. It's an evolutionary dead end. This package works very well, but the better road to take is to be sure that the newer packages all "just build" from this one rather than trying to make more releases fo this one that track all the component revisions. Robert Lipe, the author of the OpenServer specific parts of GDS, was involved very heavily with the OpenServer specific parts of EGCS. EGCS is available at http://gcc.gnu.com and mirrors. Kean Johnston also joined in the fun and together, they spent about a billion hours each hammering on this code. It, too, has good things and bad things. EGCS Advantages relative to GDS EGCS contains newer optimizations and can generate hotter code for some input. EGCS is a much newer G++ base and much more closely reflects the state of a useful C++ implementation in 1997. See also: http://gcc.gnu.org EGCS Disadvantages relative to GDS Not currently custom-installable. Key members of the Skunkware team are believed to be working on it. Currently requires the SCO assembler. No, getting clever and stealing the assembler out of the GDS will get you nowhere. 5.0.4 allegedly includes the assembler. 5.0.0 and 5.0.2 definitely do not. So if you don't have the SCO DS and you have 5.0.0 or 5.0.2, this is a problem. Non-trivial resources required to bootstrap it. It takes rjlhome (dual-processor P100) about two hours and almost 200Mb to do a full 'make bootstrap'. A full comparison of EGCS vs. GCC can be found at http://gcc.gnu.org/faq.html. I prefer EGCS becuase it's a more open environment, archives of the lists are on-line, and it is a much more integrated package - all the C++ libraries (as well as g77 and objective-c) are there and tested weekly on dozens of targets. I really feel it's a better tested release. I could probably come up with more compelling reasons to further confuse the issue, but I think if I had to optimize the heuristics used, it would be, "If you don't have the SCO DS, stay with the GDS right now." Given a choice between EGCS and GCC, I'd used EGCS. Ultimately, someone will take the time to make EGCS work well with the free assemblers so that a binary distribution of EGCS would be useful for the 5.0.0 and 5.0.2 users.

The short answer is "yes". UnixWare 2.1.x still has all of the iBCS compatibility support in it and will run OpenServer COFF binaries. You will, however, have to avoid using any of the newer OpenServer features in your program since the level of COFF support that exists in UnixWare 2.1.x is approximately equivalent to SCO ODT 3.0. UnixWare 7 product has a much higher level of compatibility with OpenServer and should be able to run pretty much any OpenServer binary (either COFF or ELF), except ones which rely on some very specific knowledge of OpenServer (eg debuggers, file system repair utilities / defragmenters, or programs which interact directly with the C2 security features and libprot) UnixWare 7 also comes with a development environment (the UDK) which enables you to build ELF binaries which will run on UnixWare 7 *and* on UnixWare 2.1.x *and* OpenServer 5.x (in the latter two cases this requires the installation of a set of comaptibility libraries on the target platform, but these are provided and are freely available). For future development work you may find that the UDK is the best way to go since it gives you compatibility across all three platforms and access to the latest versions of the language tools (C, C++, Java) and debuggers etc. Answer by Michael Davidson in comp.unix.sco.programmer. robertlipe@usa.net Note that UnixWare 7.0.1 removed support for XENIX x.out binaries.

Yes. In particular: Assuming you compile with CC -Kthread, the generated code from the compiler is thread safe. This includes static local variables with dynamic initialization expressions, which require special guards in this case. Assuming you also link with CC -Kthread, the language support runtime routines are thread safe. This means that things like exception handling, new/delete, and static init/ctor/dtor processing all work correctly in the presence of threads. The C++ Standard Library is also safe for multithreaded applications. This means that: all internal data structures in the library are protected against simultaneous access; simultaneous access to distinct containers is safe; and simultaneous read-only access to a shared container is safe. Simultaneous access to a shared container with at least one thread writing, however, must be protected by the application through the use of mutual exclusion primitives. The older pre-standard iostreams classes, and the old C++ Standard Components classes, both of which are provided for compatibility with existing applications, are not thread-safe. jls@sco.com [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : On osr5 when I dlopen a shared library I get "symbol unresolved" errors Assuming no other problems and the symbols complained of are from libc this is normally due to the dll referring to symbols that are provided statically in the linktime libc.so and not in the dynamic (runtime linked) libc.so.1. This works fine for shared libraries that are implicitly loaded ( specified as -l on link line) since the needed static symbols are loaded into the executable . If the dll is explicitly loaded (using dlload) and the symbols haven't been oth erwise referenced in the executable it will fail to resolve the symbol and the dlopen() call will fail with dlerror complaining about symbol resolution. Such static symbols can be identified as symbols that occur in a nm dump of /usr/lib/libc.so and that do not occur in one of /usr/lib/libc.so.1 Workarounds are to ensure that the static symbols are referenced in code in the executable that does the dlopen (in an uncalled dummy routine) or (better) to pull the static objects from /usr/lib/libc.so and explicitly link them into the dll when its generated. This can be seen in building tcl and TclX.

Mostly, it's understood via a combination of studying what the native compiler emits and UNIX "folklore" about how UNIX assemblers have always worked. The (sad) state of affairs is that people that should be writing assembler code just seem to be able to figure these things out. No, I won't pretend that's a good answer or one that we should be proud of. Darwinism shouldn't be justification for doc failures. You can learn a lot about the assembler syntax by watching how the compiler writes assemblers. Start with a tiny program: int x; main() { x = 0x1234; } Compile it with -S and then look at the resulting .s file. This will show you how to make symbols global, how to separate text and data, how to represent constants, and those three of four other "gotta know" things. Now, to complete the earlier setup, we'll visit history. When Intel or any other CPU vendor releases a family of processors, they almost always have an assembler written for it. The syntax for that assembler is used the examples in their databooks and is therefore a very handy thing to be able to read and possibly write. Now the Intel assembler syntax for IA32 (nee x86) isn't a very pretty thing, but it was definitely the first kid on this block. This is known as "Intel assembler syntax" and is the syntax used by most X86 assemblers including MASM last time I looked. In the mid '80's AT&T decided to flirt with porting UNIX to those 286 and 386 thingies, but decided to contract out some of the work. Assemblers are pretty boring, so that work went to either Microport or Interactive Systems Corp as legend has it. (These were the days when both these companies were known as porting houses and not as shrink-wrapped UNIX vendors.) They saw the Intel syntax and gagged. So they created their own assembler that was similar to some existing UNIX assembler - perhaps it was as much to simplify their port as it was out of "purity" of the language. This became known as "AT&T/386 assembler syntax" and is the syntax used by all the UNIX assemblers for x86 that I know of including the GNU assembler. Other than being completely different, they're quite similar. To move '1' into 32 bit memory address x, one would use: movl $1, x / AT&T syntax - move long, immed 1 -> x / "word" = 16 bits, "long" = 32. or move dword ptr x, $1 / Intel syntx. dbl word ptnr x <- immed 1 / "word" = 16 bits, so "dword" = 32. In AT&T syntax, the name of the opcode (movb, movw, movl) signfies the width of the operands. In Intel syntax, it's the funky qualifier thingies in the middle that achieves the same. There's also the minor difference that the direction is backwards between the two. So, if you find an Intel book on assembler syntax it will do you some good for an AT&T-based assembler but you have to read it in a mirror and remember to always do conversions on every line you read. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) SCO Development Environments. : What popular compilers are available? The OpenServer Development System (a.k.a. "the native development system" or "/bin/cc") is an optional SCO product. It contains a C compiler and a Cfront based C++ compiler. (This means it won't compile modern C++ code.) It provides a complete development environment (make, as, ld, headers, libraries, X11 dev, etc.) This is the kit that must be used for device driver development on OpenServer. It can generate ELF or COFF, defaulting to COFF. GCC is available for free in source form from GNU mirrors (http://egcs.cygnus.com) or in binary form from http://www.sco.com/skunkware. It provides compilers for C, modern C++, Java, Fortran 77, Objective C, and Chill. If you are using OpenServer and don't have the OpenServer Development System installed, you must be sure to install the Linkers and Libraries kit as described in the documentation of the GCC binary kit. On OpenServer, this kit can generate ELF or COFF and defaults to ELF. On UnixWare, it supports ELF only. The UDK is a next-generation development environment that is an optional product from SCO. It includes C and a modern C++ compiler. It can generate binaries that will run on OpenServer, UnixWare 2, and UnixWare 7 when appropriate runtimes are installed. This is the only available devsys for UW7. It emits ELF only which makes it unsuitable for OpenServer device drivers or generating binaries that run on pre-OpenServer SCO OSes such as ODT. GCC can be built from source to provide the "universal binary" features of the UDK following the directions in the source distribution. No known binary kits are available at this time.

If your goal is simply to block an open until DCD comes high (i.e, you're writing a dialer) just open the uppercase device like /dev/tty1A or /dev/ttyA01. If your goal is to get hardware flow control to work, look at the man pages for termio(M) and pay attention to the RTSFLOW and CTSFLOW bits. If your goal is to detect when DCD goes away, use the uppercase device as described above and be sure that CLOCAL is clear. This will deliver a SIGHUP to you when DCD drops. If your goal is to be able to wiggle DTR (not RTS), you might look at the description of B0 in termio. In my experience, this is poorly implemented in a number of serial drivers becuase it's poorly specified. For example, it's only implied that DTR gets raise again once a non-zero bit rate is specified. It's similarly unclear what the bitrate actually _is_ while you're in this mode, so if you need to process characters while DTR is low in this mode, it can be somewhat of a crapshoot. If you really, really, want to directly read and write the modem control lines on a serial port, you have two options. Many third party serial boards provide drivers that support the TIOCMGET and TIOCMSET ioctls. Most of the Digi intelligent serial board provide these ioctls. Gert Doering has modified the FAS serial driver to add support for the TIOCMGET and TIOCMSET ioctls. This patch can be found at: ftp://ftp.leo.org/pub/comp/os/unix/networking/mgetty/fas-2.12-TIOCMGET .patch Don't be fooled by the presence of these ioctls in <sys/termio.h> or be tempted to futz with -D_SVID3. They are unsupported in any SCO provided serial driver through and including the OpenServer 5.0.4 products. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) Hardware related programming : How can I directly read or write the parallel port to use it for input or to control my non-printer devices? With the SCO provided drivers through and including OpenServer 5.0.4 family, you cannot directly manipulate or read the bits in the printer port. You can communicate with custom equipment by providing your own device driver. This functionality is believed to exist in the Linux parallel port driver, so you could perhaps port that driver or at least use it as a starting place. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) Hardware related programming : How can I access to I/O ports or card memory from my program? UNIX is about sharing. While it may seem militant that it won't let you (a mere user program) go out and reset the disk controller and reprogram the interrupt controller at will, it's good for you. Honest. There is more information on doing this in this section of the FAQ. However, if you're well disciplined, have only one instance of a program talking to the device, you don't need interrupts, and are willing to accept some responsibility, it is possible to do it from user space. The classic example of this is the X server. On 5.0.0d and later it is possible to mmap() /dev/kmem into user space to talk to memory addressable hardware. To talk to I/O space is a little trickier. You can call V86_IOPL to open up permissions for inb and outb from user space. This can be a little hazardous, as it allows all I/O accesses. Alternately, you can either create your own device driver to do the ins and outs for you or you can use minor numbers 3,4,5 of the major number of the mm driver (the driver for /dev/null, mem, and kmem) to access memory as bytes, halfwords, and words, respectively. Remember that you must re-seek the I/O address each time. If you are going to do this, it is wise to encapsulate this into functions with the usual in/out[bwl] names. This is utterly undocumented and unsupported. robertlipe@usa.net [Append to This Answer] (Answer) (Category) SCO comp.unix.sco.programmer FAQ. : (Category) Hardware related programming : How can I write directly to the console like I do in DOS? This is a degenerate case of the above question. As surely as you write your program to do this, someone will have an incompatible card, will want it to run under X, or will need it from a graphic or text terminal. If your application is text, you should write your app to use curses(S). If it's graphical, coding it for X windows would be a better choice.

When gethostbyname() was used in a dynamic library with a dependency on libsocket and libc it failed to return the IP address correctly in hostent->h_addr_list[0], giving 255.255.255.255 instead of the correct address for my machine, frodo, of 192.168.0.130.

This passes the vast majority of its internal DejaGNU tests. Its about the best shape GCC has been in on OSR5 in a long while. But there are problems, especially with C++. The way they handle template instantiation is awkward. You may find you need to link C++ programs and shared libraries with -Wl,-z -Wl,multidefs. The real solution is for us to change our link editor to recognize these .gnu.linkonce sections and obey them, or to get the GNU link editor working on OSR5, something I am fairly close to getting right but it is still a way off. But at least this gets you most of the way there. I am curious to know how this works out for you. This set of patches adds full support for gjc, the GNU Java Compiler.
