    Makefile need debug option

    Hi gurus,

    Can someone quickly remind me how I can add a -g (to generate the
    debug table inside the core file) so I can run it against GDB and find
    out whats happening. I tried to put it in the right after the $(CC)
    as in $(CC) -g .... But it didn't work. The core file shows no
    stack in GDB
    By the way, I am compiling on a Linux box. This is a makefile from a
    piece of code that i need to maintain. TIA




    =============== =========== THE MAKEFILE FOLLOWS =============== =====

    I=$(CUST)/src/include
    MAKEINCDIR=$(I)/Makefiles
    DIRNAME=SendFti r

      This isn't a C question. comp.unix.progr ammer is probably your best
      bet, or possibly one of the Linux groups.

              Try setting CFLAGS to -g in your makefile.
              >I tried to put it in the right after the $(CC)

              That should work.
              >The core file shows no stack in GDB
              Do you really mean it shows no stack? Or just that it doesn't show
              the names of functions on the stack? If there's no stack, it probably
              means that the bug has completely screwed up the stack pointer.

                  Try:
                  CFLAGS = $(CDEBUGFLAGS)
                  CDEBUGFLAGS = -g

                  I think, you have not linked the CFLAGS with CDEBUGFLAGS. Did you
                  cross-check that .
                  Else, try directly the CFLAGS = -g in the makefile.

                  The -g option should make it work .
