Clang ++ 4.0.0 Windowsでのコンパイルエラー

Windows 10（32ビットOS、x86プロセッサ）上でソースからコンパイルされたclang 4.0.0を使用しています。私はフォーマットllvm irコードに私のcppコードをコンパイルしようとしています。Clang ++ 4.0.0 Windowsでのコンパイルエラー

#include <windows.h> 
#include <tlhelp32.h> 
#include <fstream> 
#include <mapi.h> 
#include <memory> 
#include<stdio.h> 

/* Function to calculate x raised to the power y */ 
int power(int x, unsigned int y) 
{ 
    if (y == 0) 
     return 1; 
    else if (y%2 == 0) 
     return power(x, y/2)*power(x, y/2); 
    else 
     return x*power(x, y/2)*power(x, y/2); 
} 

/* Program to test function power */ 
int main() 
{ 
    int x = 2; 
    unsigned int y = 3; 

    printf("%d", power(x, y)); 
    return 0; 
}

これは単なるサンプルコードですが、それは記載されているヘッダファイルをインクルードすべてのC++のコードで同じ動作です：ここで打ち鳴らすを使用してコンパイルに失敗したサンプルコードです。私はLLVMのIRコードにコンパイルし、次のコマンドを使用します。コンパイルで

clang++ -S -emit-llvm assiral.cpp -o assiral.ll

私は次のエラーを取得する：私は、コマンドを実行した後に何を期待

C:\Sample>clang++ -emit-llvm -S assiral.cpp -o assiral.ll

は、生成されたバイトコードファイルを持つことです（.llファイル）。私は多くの投稿を見てきました。ここにはフラグと共に '-fms-compatibility-version = 19'があります。しかし、追加されたフラグは、未知の引数としてフラグが立てられます。私はMSVS 2017で作業しています。おそらく、このフラグを間違って使用しています。しかし、私は今この苦境にいました。どんな助けや提案も大歓迎です。

最小限のコンパイル可能な例を含めてください。 – OmnipotentEntity

質問を更新していただきありがとうございます。 Windows固有のヘッダーを削除するソースを少し変更するだけで、Linuxでうまくコンパイルできます。そこで、トラブルシューティングを開始します。インクルードを並べ替えて不要なものを削除してみてください。 – OmnipotentEntity

正確にはどういう意味ですか？ヘッダーの問題のため、コンパイルの段階には達しません。 –

これは、環境変数INCLUDEのヘッダーファイルに正しいパスを追加することで修正されました。パスを修正すると、ほとんどのエラーが解決されました。これには、windows.hのような特定のヘッダーを参照するC++ファイルをコンパイルすると、ファイルが見つからないというエラーが含まれます。同じことを行う方法について

リンク：List all environment variables from command line?

あなたはまた別の問題が解決できます。LIBCMT.LIBの正しい場所を指すようにLIBPATH環境変数を設定することにより、

link fatal error lnk1104 cannot open file 'libcmt.lib'

をファイル。私は私のものを見つけました：

C:\Program Files\Microsoft Visual Studio 14.0\VC\lib

これらの些細な問題は私には分かりませんでした。これが誰かに同じ問題を救うことを願っています。
