Does the version of compiler infuce the performance of gdb?

[Linda]

I wrote a rather simple program named main.cpp, which is like the
follows:

int main()
{
    return 0;
}

And its Makefile is like the follows:

CCC=/opt/SUNWspro/bin/CC

DEBUG= -g

CFLAGS=$(DEBUG)

main  : main.o
        $(CCC) $(CFLAGS) $^ -o $@
main.o: main.cpp
        $(CCC) -c $(CFLAGS) -o $@ $?
clean:
        rm -f *.o
        rm main

After I type "make" on the screen, I got its executable file named
main.

But when I type "gdb main", I got:

GNU gdb 5.0

This GDB was configured as "sparc-sun-solaris2.6"...(no debugging
symbols found)...

So I cannot debug normally. But if I change CCC to g++, gdb can work
normally. So is the version of the compiler is crucial for gdb? And how
can I make gdb work normally?

Thanks!
