Enabling debug symbols in shared library using GCC

Question

I am creating a shared library using gcc and suspect that there may be some memory leaks from the shared library. To debug, I need to enable debug symbols when creating the shared library.

To build, I am using gcc -g ... (-g is for enabling debug information)

But the library (*.so file) size is not changing for both -g, and without -g. Besides, I am not getting any useful information from tools like VALGRIND.

Can anyone point me the mistake?

Solution

You need to use -g for all the steps (compiling your source files and linking).

Can you post the relevant parts of your makefile, or the other CFLAGS being used?

I added -g to CFLAGS and it worked, thanks !!!

Also make sure you don't specify -s when linking, because this strips debug info.

The -g flag is not really needed for the gnu linker as the ld man page says: "-g Ignored. Provided for compatibility with other tools.". It is only required for the compilation stage.
