15)* How can I find which version of Motif I have? Xlib or Xt

version?
[Last modified: Jan 02]

Answer: The macro XmVERSION gives you the version number.  The macro
XmREVISION gives you the major revision number.  The macro XmVersion combines
these e.g. a value of 1002 is Motif 1.2.  In Motif 1.2, the macro
XmUPDATE_LEVEL was added to give the minor revision number (also known as the
patch level).

To find the version of a compiled Motif library:

    grep XmVERSION_STRING libXm.a

To find the Motif version at run-time, use the global variable:

    xmUseVersion

Ken Lee adds the following for determining the Xlib and Xt version:

X11/Xlib.h should have macros like this:
#define XlibSpecificationRelease 6
meaning X11R6.

Similarly, X11/Intrinsic.h has this in X11R6:
#define XtSpecificationRelease 6
