source.c ------------------------- #include <stdio.h> int main () { printf ("Hello world\n"); } ------------------------- A couple of you answered my first query which gave me.... gcc -nostdinc -I/includedir -nostdlib -L/libdir source.c This always failed with either.... ld: No reference to __DYNAMIC collect2: ld returned 1 exit status or /var/tmp/ccdgopIG.o: Undefined symbol `___main' referenced from text segment /var/tmp/ccdgopIG.o: Undefined symbol `_printf' referenced from text segment /var/tmp/ccdgopIG.o: Undefined symbol `_printf' referenced from text segment collect2: ld returned 1 exit status Depending on whether I specified lib names (ex. -lnet -lpcap -lgcc, etc....) I finally pulled all my hair out and ran gcc -nostdinc -I/usr/include -nostdlib -L/usr/lib source.c =-= and =-= gcc -nostdlib -L/usr/lib source.c and again I received..... /var/tmp/ccdgopIG.o: Undefined symbol `___main' referenced from text segment /var/tmp/ccdgopIG.o: Undefined symbol `_printf' referenced from text segment /var/tmp/ccdgopIG.o: Undefined symbol `_printf' referenced from text segment collect2: ld returned 1 exit status Can anyone assist with this? I need to be able to compile and link a "Hello World" program against a proprietary lib dir for my project but for starters I have to make sure my anomolies are not with the "ld" portion of my build. Why doesn't "gcc -nostdlib -L/usr/lib source.c" link properly? I even added all the .a files with -lnet -lpcap -ledit, so forth.... and it still failed. Please reply to all. If I need to direct this to our gcc brethren then please advise. -- Andrew Otwell, MSS Special Ops Recon/Surveillance/Developer desk 678.443.6271, aotwell@iss.net, http://www.iss.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
