[olsr-dev] using gdb on the plugins
Mon Nov 15 15:58:40 CET 2004
Hmm. Are you sure that you are compiling your library with debug information?
My compiler options are : -Wall -fPIC -g
the -g is debug info, and I have no trouble finding line number information in the GDB.
My biggest problem is in fact setting gdb/DDD up so that it finds the file, but I
have never had problems with the line number information.

I said as you told me. However, still the same, that I cannot step line
by line through the plugin's source code.
I attached a log file showing what I did within gdb. Maybe someone could
try to reproduce this. I've already been trying to get around this for
some hours. And google only tells me about a bunch of mail threads,
which I did not find very helpful so far :(
