opencv無法與vtk_on

即時通訊使用ubuntu 14.04。我已經成功安裝了vtk8.0.0。opencv無法與vtk_on

現在我想用vtk構建opencv2.4.13.2。

而且總會有錯誤，請參閱下文。

有人有想法，該如何解決？非常感謝！

VTK 8.0和更高版本需要一個C++ 11編譯器（nullptr是一個C++ 11功能）。你安裝了一個預先構建的VTK嗎？如果是這樣，請檢查你正在使用gcc 4.8或更高版本，並確保你的C++標誌包括-std=c++11（你可以嘗試將其添加到您的OpenCV的建立CMakeCache.txt的CMAKE_CXX_FLAGS條目，看看錯誤消失。

我建造VTK所以我認爲我有C++編譯器，但它不會被默認使用，我怎樣才能將它添加到CMakeCache.txt中？像這樣？ //編譯器在所有構建類型中使用的標誌 CMAKE_CXX_FLAGS：STRING =「-std = C++ 11」 – Yongzhi

我想也許這個錯誤已經消失了，但是我現在在使用CUDA時遇到了麻煩[29％]構建NVCC（設備）對象 /usr/lib/gcc/x86_64-linux-gnu /4.8/include/stddef.h(432）：error：identifier「nullptr」is undefined。看來，CUDA8不是與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
