C++コードでLLVM APIを使用しようとしていますが、リンカエラーが発生します。私はApple MacOSX Lionに取り組んでいます。コンパイルにg ++を使用する。これは、エラーをスローしているCreateGlobalStringPtrです。これはLLVM 3.0です。ここでLLVMライブラリをリンクしようとするとコンパイルエラーが発生する
はコードです:
#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");
}
