How to generate Debug symbols with Makefile for C? [Linux]

Question

I\'m trying to use GDB and KDEvelop to debug a console app under Knoppix VM. KDevelop and GDB don\'t break at my breakpoints. I suspect it\'s because they don\'t have debug symb

Answer 1

The full example would be:

CFLAGS =-g

all: program.o
    gcc -o program program.o

The CFLAGS here is applied to both the compiler and the linker.

Answer 2

Include -g in the flags sent to the compiler and linker. The default variables for this are CFLAGS and LDFLAGS respectively.

The second step: exclude -s from flags (-s means strip)

Answer 3

If you are able to see source and set the breakpoint, then you probably have debugging symbols established. However, the usual sequence is:

gcc -g -o (outputname) (source files...)
gdb outputname

Give more specifics about what you are doing and what messages you see and we can be more specific.
