That depends on what the ``standalone'' code contains. If your foo.o object file defines a 'main' function, then you can just use cc(1): % tesla:/tmp/foo$ cat -n foo.asm % 1 global main % 2 main: % 3 mov eax,1 ; exit() syscall % 4 mov ebx,1 ; exit code % 5 int 0x80 ; trap into kernel % tesla:/tmp/foo$ nasm -f elf -o foo.o foo.asm ==> % tesla:/tmp/foo$ cc -o foo foo.o % tesla:/tmp/foo$ ./foo % tesla:/tmp/foo$ echo $? % 1 % tesla:/tmp/foo$ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
