Base on the gdb manu we can pass argument as gdb --args gcc -02 -c
foo.c
But how to use makefile instead of gcc
I try gdb --args make -f Makefile.test but failed.
This is a C++ language discussion group. Your post is off-topic for two
reasons: (1) You are using C, which is very different from C++, and (2)
gdb is a general-purpose debugging tool, and not an aspect of the C++
programming language.
Below is one possible (not particularly scalable) approach. You will
likely get a better answer in a more appropriate group.
$ ls
Makefile foo.c
$ cat Makefile
CC=gcc
DB=gdb
EXT=.c
CFLAGS=-ansi -pedantic
DBFLAGS=--quiet
INVOCATION=$(CC) $(CFLAGS) -o $(TARGET) $(TARGET)$(EXT)
$(TARGET): $(TARGET)$(EXT)
$(INVOCATION)
db:
$(DB) $(DBFLAGS) --args $(INVOCATION)
$ TARGET=foo make
gcc -ansi -pedantic -o foo foo.c
$ ls
Makefile foo foo.c
$ rm foo
$ TARGET=foo make db
gdb --quiet --args gcc -ansi -pedantic -o foo foo.c
