Hi all,
I need to compile a program with the debug flag "-g". The program uses some (static) libraries which have already been compiled without the "-g" flag. So, if I need all the debugging information ( line numbers etc. ) even from the libraries, do I need to recompile the libraries? Or is the "-g" flag just for the program, enough to bring all info?
I use "gcc" and "gdb".
What is the "correct" thing to do? Any advice would be greatly appreciated.
Thanks in advance,
Venkat.

And pick the same debugging information format (stabs or dwarf) for both,
app and libs.

In general you will have no problems, I did not work with static
libraries, but with shared ones never had a problem. I do not think that
recompiling the libraries with debug info provides much help, unless the
libraries are buggy.

Thanks for the responses. I thought I could get away with not compiling
the libraries.
Thanks anyway,
Venkat.
