Yes, the kenel is 64 bit, but you may still have a pure 32
bit userspace (thats what my dual G5 PowerMac running Linux
has).

Does your maching have directories like /lib64 and /usr/lib64?

If you compile a program like:

    #include <stdio.h>
    int main (void) {
        printf ("sizeof (void*) : %zd\n", sizeof (void*)) ;
        return 0 ;
    }

what is the size of a void pointer?

Does this change if you add -m64 to the gcc command line?

Hi, Erik

  Thanks for your reply.

Yes, it has /lib64 and /usr/lib64.

$ ./a.out
sizeof (void*) : 8

No.

Ok, as far as I cam tell, everything on your system is
correct.

I don't have any further ideas for you to test.
