opencv无法与vtk_on

即时通讯使用ubuntu 14.04。我已经成功安装了vtk8.0.0。opencv无法与vtk_on

现在我想用vtk构建opencv2.4.13.2。

而且总会有错误，请参阅下文。

有人有想法，该如何解决？非常感谢！

VTK 8.0和更高版本需要一个C++ 11编译器（nullptr是一个C++ 11功能）。你安装了一个预先构建的VTK吗？如果是这样，请检查你正在使用gcc 4.8或更高版本，并确保你的C++标志包括-std=c++11（你可以尝试将其添加到您的OpenCV的建立CMakeCache.txt的CMAKE_CXX_FLAGS条目，看看错误消失。

我建造VTK所以我认为我有C++编译器，但它不会被默认使用，我怎样才能将它添加到CMakeCache.txt中？像这样？ //编译器在所有构建类型中使用的标志 CMAKE_CXX_FLAGS：STRING =“-std = C++ 11” – Yongzhi

我想也许这个错误已经消失了，但是我现在在使用CUDA时遇到了麻烦[29％]构建NVCC（设备）对象 /usr/lib/gcc/x86_64-linux-gnu /4.8/include/stddef.h(432）：error：identifier“nullptr”is undefined。看来，CUDA8不是与C++ 11兼容？即使我激活了CUDA_SEPARABLE_COMPILATION。 – Yongzhi

我不熟悉OpenCV的cuda支持。抱歉。 – Drone2537
