Is the version of a compiler crucial for 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!
