[LLVMdev] CreateGlobalStringPtr giving linker errors

[Arpan Sen]

Hi,

I am trying to use some LLVM API in my C++ code, and I end up getting
linker errors. I am working on Apple MacOSX Lion. Using g++ for the
compile. It is the CreateGlobalStringPtr which is throwing the error. This
is LLVM 3.0.

Here's the codeI am trying to use some LLVM API in my C++ code, and I end
up getting linker errors. I am working on Apple MacOSX Lion. Using g++ for
the compile. It is the CreateGlobalStringPtr which is throwing the error.
This is LLVM 3.0.

Here's the code:

#define __STDC_LIMIT_MACROS
#define __STDC_CONSTANT_MACROS

#include "llvm/Support/DataTypes.h"
#include "llvm/Support/IRBuilder.h"
#include "llvm/LLVMContext.h"
#include "llvm/Module.h"
#include "llvm/Constants.h"
#include "llvm/Function.h"
#include "llvm/BasicBlock.h"
int main()
{
  llvm::LLVMContext & context = llvm::getGlobalContext();
  llvm::Module *module = new llvm::Module("top", context);
  llvm::IRBuilder<> builder(context);
  llvm::Value *helloWorld = builder.CreateGlobalStringPtr("hello world!\n");
}


And here's the error:
