[LLVMdev] link issue with InitializeNativeTarget

[Zhoulai]

Hi,

Excuse me but I have struggled with a  link issue when compiling this
one-line program,  "Hello.cpp":


#include "llvm/Support/TargetSelect.h"
using namespace llvm;
int main(int argc, char **argv) {
  InitializeNativeTarget();

}

I use this command line:

 g++ -o Hello  `llvm-config --libs --cxxflags --ldflags` ../src/Hello.cpp

The error message:

Hello.cpp:(.text._ZN4llvm22InitializeNativeTargetEv[_ZN4llvm22InitializeNativeTargetEv]+0x5):
undefined reference to `LLVMInitializeX86TargetInfo'
Hello.cpp:(.text._ZN4llvm22InitializeNativeTargetEv[_ZN4llvm22InitializeNativeTargetEv]+0xa):
undefined reference to `LLVMInitializeX86Target'
Hello.cpp:(.text._ZN4llvm22InitializeNativeTargetEv[_ZN4llvm22InitializeNativeTargetEv]+0xf):
undefined reference to `LLVMInitializeX86TargetMC'
collect2: error: ld returned 1 exit status

Any hint for the problem source? I am using LLVM 3.7 on a ubuntu 14.04
(VM). Thanks.
