gangを使用してclang/llvmでリンクに失敗する

Question

この.ccpファイルをコンパイルしようとしています。私はhttps://github.com/loarabia/Clang-tutorialからそれを得た。

#include <iostream> 

#include "llvm/Support/raw_ostream.h"

int main() 
{ 
    clang::DiagnosticOptions diagnosticOptions; 
    clang::TextDiagnosticPrinter *pTextDiagnosticPrinter = 
     new clang::TextDiagnosticPrinter(
      llvm::outs(), 
      diagnosticOptions); 
    llvm::IntrusiveRefCntPtr<clang::DiagnosticIDs> pDiagIDs; 
    //clang::DiagnosticIDs diagIDs; 

    clang::DiagnosticsEngine *pDiagnosticsEngine = 
     new clang::DiagnosticsEngine(pDiagIDs, pTextDiagnosticPrinter); 

    clang::LangOptions languageOptions; 
    clang::FileSystemOptions fileSystemOptions; 
    clang::FileManager fileManager(fileSystemOptions); 
    clang::SourceManager sourceManager(
     *pDiagnosticsEngine, 
     fileManager); 
    clang::HeaderSearch headerSearch(fileManager, *pDiagnosticsEngine); 

    clang::TargetOptions targetOptions; 
    targetOptions.Triple = llvm::sys::getDefaultTargetTriple(); 

    clang::TargetInfo *pTargetInfo = 
     clang::TargetInfo::CreateTargetInfo(
      *pDiagnosticsEngine, 
      targetOptions); 
    clang::CompilerInstance compInst; 

    clang::Preprocessor preprocessor(
     *pDiagnosticsEngine, 
     languageOptions, 
     pTargetInfo, 
     sourceManager, 
     headerSearch, 
     compInst); 

    return 0; 
} 

そして、私はこのような行をコンパイル++グラム使用：

g++ tutorial1.cpp -g -fno-rtti `llvm-config --cxxflags --ldflags --libs` -lclangBasic 
-lclangLex -lclangDriver -lclangFrontend -lclangParse -lclangAST -lclangSema

-I/Users/scher/Documents/Projects/task/C/last_clang/build/include 
-I/Users/scher/Documents/Projects/task/C/last_clang/build/tools/clang/include 

しかし、それは次のレポートで失敗します。ときに私は、それが発生したことを追加したい

コードclang::CompilerInstance compInst;を追加してください。この行がなければ、通常通りコンパイルされます。

また、私は打ち鳴らす/ LLVM 3.0を使用し、それは、このチュートリアルにそれが失敗した理由http://clang.llvm.org/get_started.html

任意の提案を使用して構築されましたか？

Answer 1

正しいライブラリを正しい順序でリストしていない可能性があります。私は正しいリストが私の頭の上にあるのかどうかわかりませんが、少なくともあなたは失われています-lclangSerialization。

Answer 2

コマンドラインでのライブラリの順序が間違っている可能性があります。プロジェクトで指定されたmakefileを使用してみてください。https://github.com/loarabia/Clang-tutorial/blob/master/makefile makefileをあなたのディレクトリにコピーし、makeを実行するだけです。
