c++ - VisualStudio2012でのGoogleTest

Question

ユニットテストを始めようとしています。gtestの最新ビルドをダウンロードし、に解凍A:\gtestしました。指定された手順に従って、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、エラーが山積みになります。

私は何か間違ったことをしていますか、それともこれは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ていません。gtestについて非常に良いことを聞いたばかりです。

Answer 1

VC ++ 2012は、可変個引数テンプレートをサポートしていません（今後もサポートしません）。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。このブログ投稿に記載されているように、偽の可変個引数テンプレートパラメータの数はデフォルトで5になっています。問題は、gtestが最大std::tuple<>10個のテンプレート引数を使用してインスタンス化しようとしていることです。

ブログ投稿で言及されているように、_VARIADIC_MAX最大​​10個のパラメーターをサポートするようにプロジェクト全体でマクロを定義できます。プロジェクトのプリプロセッサ定義設定を使用してこれを実行することをお勧めしますが、重要なことは、stdlibヘッダーを（直接的または間接的に）含める前に、すべてのTUがそれを定義していることを確認することです。

Answer 2

マクロを使用してVS2012タプルの実装を変更するのではなく_VARIADIC_MAX、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

0に設定GTEST_HAS_TR1_TUPLEすると、gtestがSTLヘッダーからタプルクラスを使用しようとするのを防ぎます。1に設定GTEST_USE_OWN_TR1_TUPLEすると、タプルのサポートを必要とする機能を省略するのではなく、独自のタプル実装を使用するようにgtestに指示します。私は個人的に、STL実装を微調整するよりもこのオプションを好みました。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機能するはずです。

Answer 3

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

Answer 4

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追加します。
