Visual Studio 2012のGoogleテスト
ユニットテストを開始しようとしています。 gtestの最新ビルドをダウンロードし、A:\gtestに抽出しました。指示に従って、gtest.slnを開きました。 Visual Studioでは、更新に同意した場合にのみslnを開くことができます。次に、ビルドしようとすると、エラーの山が表示されます：

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
私は何か間違ったことをしていますか、これはVS2012の問題ですか？私はグーグルテストに執着しておらず、VSでうまく機能する場合は別のフレームワークを使用することに反対しません。gtestについて非常に良いことを聞いたばかりです。
VC++ 2012は可変長テンプレートをサポートしていません（サポートしません）。その結果、その標準ライブラリの実装は、プリプロセッサで生成されたオーバーロードと特殊化を使用してそれらを偽造しようとします。 このブログ記事 notesのように、偽の可変長テンプレートパラメータの数はデフォルトで5に設定されています。問題は、gtestがstd::Tuple<>最大10個のテンプレート引数。
ブログの投稿で言及しているように、_VARIADIC_MAX最大10個のパラメーターをサポートするプロジェクト全体のマクロ。おそらくプロジェクトの プリプロセッサ定義 設定によってこれを行いたいと思うでしょうが、重要なことは、すべてのTUがstdlibヘッダーを含める前に必ず定義することです（直接または間接）。
_VARIADIC_MAXマクロを使用してVS2012 Tuple実装を変更するのではなく、gtestプロジェクトとgtestヘッダーを含むプロジェクトで次の2つのマクロを定義することでこの問題を解決しました。
GTEST_HAS_TR1_Tuple=0
GTEST_USE_OWN_TR1_Tuple=1
GTEST_HAS_TR1_Tupleを0に設定すると、gtestがSTLヘッダーからTupleクラスを使用しようとするのを防ぎ、GTEST_USE_OWN_TR1_Tupleを1に設定すると、gtestがTupleサポートを必要とする機能を省略せずに独自のTuple実装を使用するように指示します。私は個人的に、このオプションをSTL実装の調整よりも好みました。このソリューションは、同様の問題を抱えている他のコンパイラーでも動作するはずです。
これはバージョンr675で修正されています。 https://code.google.com/p/googletest/source/detail?r=675 を参照してください
また、最新バージョンを入手するまで、GTEST_USE_OWN_TR1_Tuple=0プリプロセッサ定義に。
