編譯OpenCV的3.3：C++ 11不支持

我試圖編譯OpenCV 3.3新版本（發佈於2017年8月3日），但我得到的C++11編譯OpenCV的3.3：C++ 11不支持

錯誤這是我cmake命令行：

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 ..

我已經通過接通一些組件編輯CMakeLists（即使不進行任何更改，誤差保持相同）：

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

在這裏，我CMakeError.log文件：

編輯

CMake的版本-3.5

GNU編譯器5.4。 1

EDIT2

我與GNU編譯7.1.0現在，但我得到不同的錯誤

Build output check failed: 
    Regex: 'command line option .* is valid for .* but not for C\+\+' 
    Output line: 'cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++'

你是否對原來的OpenCV'CMakeLists.txt'做了一些修改？ –

@DanMašek是的，我打開了OCV_OPTION中的一些組件，我將在以後使用 –

好的，你可以（不要粘貼這個相當長的文件塊）來總結這些變化，或者提供一個diff？ |如果你添加'-DENABLE_CXX11 = OFF'給你的cmake命令行怎麼辦？ –

我終於從源碼編譯OpenCV 3.3成功，但我仍然不知道爲什麼它不會編譯以前。所有我所修改爲標誌OPENCV_EXTRA_MODULES_PATH到的opencv_contrib 3.3.0模塊的源文件，像這樣的參考：

$ 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 ..

我有一種警告（和許多其他）的無限數量：

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

，你也可能會得到一個錯誤與不支持CUDA的GCC新版本：但是這

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

可以通過設置cmake使用的GCC舊版本在編譯OpenCV

CMAKE_C_COMPILER=/usr/bin/gcc-5

這個解決方案爲我工作。「OPENCV_EXTRA_MODULES_PATH」的值存在拼寫錯誤。修復它到適當的值解決了C++ 11錯誤。 – exhuma

這裏的問題是不是你要使用C++ 11，但完全opposit中，源代碼依賴於它（根據給出的auto res = test();這是一個C++ 11功能的錯誤來判斷）。

對於GCC 5.4，默認的C++標準是帶有GNU擴展的C++ 98，如documentation所述，但您可以使用-std=c++11明確設置C++ 11標準（在GCC 5.4中幾乎完全支持）旗。這將可能解決問題，但更新到GCC 7.1（如馬克Setchell建議）是更好的主意和解決問題的框（7.1的默認標準是GNU擴展的C + + 14）。

至於如何傳遞的標誌：你只需要添加set(CMAKE_CXX_FLAGS "-std=c++11")到的CMakeLists.txt的開頭或添加的CMake GUI中的字符串條目，其中名稱是CMAKE_CXX_FLAGS和值-std=c++11。

我遇到了與@Ja_cpp相同的問題。不幸的是，這個解決方案並不適合我。 –

現在我正在用GNU 7.1.0編譯，我得到了不同的錯誤！ –

我無法評論你的答案，所以我要繼續寫下我的。 '-Wmissing-prototypes'不是一個有效的C++標誌（雖然它適用於C），所以我絕對不知道它爲什麼被使用，也許CMake沒有找到正確的編譯器。至於警告;他們在編譯OpenCV時期待（至少它們是我的經驗），但是那些與C++ 11相關的_might_會使用'-DENABLE_CXX11 = ON'標誌消失。 – user2986898

我在Linux Mint的18.2 OpenCV的安裝3.3.1得到解決，接下來這篇文章（https://www.learnopencv.com/install-opencv3-on-ubuntu/）和我有同樣的問題。我從

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 ..

改變cmake的命令

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 ..

（改變從-D CMAKE_INSTALL_PREFIX=/usr/local \到-DCMAKE_INSTALL_PREFIX=/usr/local \），它爲我工作。希望有用。注意：3.3.0不起作用。（對不起我的英文）
