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.
