Tutorials for gdb suggest compiling with ‘gcc -g’ to compile the program with debug symbols.

However, I want to debug a program compiled with make. How can I instruct make to compile with debugging symbols?

Thanks.

    In order to change your compile options you need to edit the file ‘Makefile’ in the directory from which you run ‘make’. Inside that file look for one of the following things:

    1. The variable which defines you compiler, probably something like:

      CC=’gcc’

    2. The actual line where your compiler gets called (more likely in hand-made Makefiles).

    3. Variables called CFLAGS or CXXFLAGS

    In the first two cases, just add ‘-ggdb’ after ‘gcc’, in the third case it’s even easier just add ‘-ggdb’ like:

    CFLAGS='-ggdb'
