Getting Started with GDB139
Now let us debug the output file. Note that when starting
gdb
, you use the output file
sum
on the command line and
gdb
will automatically find out the source code file name (
sum.c
)
from the information stored inside the executable file. An explanation of different
gdb
com-
mands is provided at the end of this debug session. Note that the
next
command is abbreviated
as
n
in this session.
