我想在我的C++代碼中使用一些LLVM API,並且最終得到鏈接器錯誤。我正在研究Apple MacOSX Lion。使用g ++進行編譯。它是拋出錯誤的CreateGlobalStringPtr。這是LLVM 3.0。試圖鏈接LLVM庫時編譯錯誤

下面的代碼:

#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"); 
}

爲什麼要鏈接到一些隨機名爲.dylib(這肯定是從LLVM 2.9或周圍產生,因爲這是最後一個版本用LLVM-GCC)?使用llvm-config爲編譯器/鏈接器派生適當的標誌。
