[LLVMdev] fPIC

[Ryan M. Lefever]

On my 32 bit linux box, things seam to work find, but on my 64 bit linux 
box I am getting problems.

I have the following c file (lib.c):
--------------------------------
#include <stdio.h>

void libmethod(){
   printf("libmethod()\n");
}
-------------------------------

I tried to get a shared library using the following commands:

llvm-gcc -emit-llvm -Wall -fPIC -c -o lib.opt.bc lib.c -O3

llvm-ld -native -Xlinker=-shared -Xlinker=-Wl,-soname,libmylb.so -o 
libmylb.so lib.opt.bc

The llvm-ld command fails with the following message:

/usr/bin/ld: /tmp/ccWOiWYc.o: relocation R_X86_64_32S against `a local 
symbol' can not be used when making a shared object; recompile with -fPIC
/tmp/ccWOiWYc.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
llvm-ld:

Does anyone know what is going on?  Do I need to specify different options?

Thanks,
Ryan
