OpenCV 3.3のコンパイル：C ++ 11はサポートされていません

OpenCV 3.3（2017年8月3日リリース）の新しいバージョンをコンパイルしようとしていますが、C++11のエラーが発生しています

これは私のcmakeコマンドラインです：

cmake -D CMAKE_BUILD_TYPE=RELEASE \ 
-D CMAKE_INSTALL_PREFIX=/usr/local \    
-D WITH_CUDA=ON \    
-D ENABLE_FAST_MATH=1 \    
-D CUDA_FAST_MATH=1 \    
-D WITH_CUBLAS=1 \    
-DINSTALL_C_EXAMPLES=OFF \    
-D INSTALL_PYTHON_EXAMPLES=ON \    
-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.3/modules \    
-D BUILD_SHARED_LIBS=ON \    
-D WITH_GTK=ON /    
-D BUILD_EXAMPLES=ON ..

一部のコンポーネントをオンにしてCMakeListsを編集しました（変更を加えなくても、エラーは同じままです）。

OCV_OPTION(WITH_OPENGL         "Include OpenGL support"                      ON  IF (NOT Android AND NOT WINRT) )
OCV_OPTION(WITH_OPENVX         "Include OpenVX support"                      ON)
OCV_OPTION(WITH_OPENNI         "Include OpenNI support"                      ON  IF (NOT Android AND NOT IOS AND NOT WINRT) )
OCV_OPTION(WITH_OPENNI2        "Include OpenNI2 support"                     ON  IF (NOT Android AND NOT IOS AND NOT WINRT) )
OCV_OPTION(WITH_OPENMP         "Include OpenMP support"                      ON)
OCV_OPTION(WITH_OPENCL_SVM     "Include OpenCL Shared Virtual Memory support" ON ) # experimental

そして、ここに私のCMakeError.logファイル：

GNU 7.1.0でコンパイルしていますが、別のエラーが発生します

最終的にソースからOpenCV 3.3を正常にコンパイルしましたが、なぜ以前はコンパイルできなかったのかまだわかりません。変更したのは、OPENCV_EXTRA_MODULES_PATHのモジュールのソースファイルがある参照へのフラグopencv_contrib 3.3.0だけです。

$ cmake \
-D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D WITH_CUDA=ON \
-D ENABLE_FAST_MATH=1 \
-D CUDA_FAST_MATH=1 \
-D WITH_CUBLAS=1 \
-D INSTALL_C_EXAMPLES=OFF \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D OPENCV_EXTRA_MODULES_PATH=/home/jhros/opencv-3.3.0/opencv_contrib-3.3.0/modules  \
-D BUILD_SHARED_LIBS=ON \
-D WITH_GTK=ON \    
-D BUILD_EXAMPLES=ON ..

私は無限の種類の警告（および他の多くの警告）を受け取りました。

warning: dynamic exception specifications are deprecated in C++11

また、cudaでサポートされていないGCCの新しいバージョンでエラーが発生する場合があります。

#error -- unsupported GNU version! gcc versions later than 5 are not supported!

しかし、これはcmakeをコンパイルするときにGCCの古いバージョンを使用するようにOpenCVを設定することで解決できます。

CMAKE_C_COMPILER=/usr/bin/gcc-5

Linux Mint 18.2にOpenCV 3.3.1をインストールし、この記事（ https://www.learnopencv.com/install-opencv3-on-ubuntu/ ）に従い、同じ問題が発生しました。からcmakeコマンドを変更しました

cmake -D CMAKE_BUILD_TYPE=RELEASE \
  -D CMAKE_INSTALL_PREFIX=/usr/local \
  -D INSTALL_C_EXAMPLES=ON \
  -D INSTALL_PYTHON_EXAMPLES=ON \
  -D WITH_TBB=ON \
  -D WITH_V4L=ON \
  -D WITH_QT=ON \
  -D WITH_OPENGL=ON \
  -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
  -D BUILD_EXAMPLES=ON ..

に

cmake -D CMAKE_BUILD_TYPE=RELEASE \
  -DCMAKE_INSTALL_PREFIX=/usr/local \
  -D INSTALL_C_EXAMPLES=OFF \
  -D INSTALL_PYTHON_EXAMPLES=OFF \
  -D WITH_TBB=ON \
  -D WITH_V4L=ON \
  -D WITH_QT=ON \
  -D WITH_OPENGL=ON \
  -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
  -D BUILD_EXAMPLES=OFF ..

（-D CMAKE_INSTALL_PREFIX=/usr/local \から-DCMAKE_INSTALL_PREFIX=/usr/local \に変更）、それは私にとってはうまくいきました。役に立つことを願っています。注：3.3.0は機能しません。 （私の英語はごめんなさい）

ここでの問題は、C++ 11を使用しようとしていることではなく、正確に反対です。ソースコードはそれに依存しています（C++ 11の機能であるauto res = test();に与えられたエラーによって判断します）。

GCC 5.4の場合、デフォルトのC++標準はC++ 98で、GNU拡張機能、 ドキュメント に記載されているとおりですが、C++ 11標準を明示的に設定できます（ GCC 5.4ではほぼ完全にサポートされています）-std=c++11フラグを使用すると、おそらくが問題を解決しますが、GCC 7.1への更新（Mark Setchellの推奨）はるかに優れたアイデアであり、箱から出して問題を解決します（7.1のデフォルトの標準は、C++ 14でGNU拡張機能）です。

フラグを渡す方法については、set(CMAKE_CXX_FLAGS "-std=c++11")をCMakeLists.txtの先頭に追加するか、名前がCMAKE_CXX_FLAGSで値が-std=c++11であるCMake GUIに文字列エントリを追加するだけです。

-DENABLE_CXX11 = ONを追加すると解決します
