我正在尝试使用CUDA 8.0支持编译opencv（我在没有CUDA的情况下成功编译了它）。由于我只需要cv::cuda::SURF_CUDA和cv::xfeatures2d::SURF，因此我禁用了大多数模块。
这是我的cmake配置：

但是，如果我运行make或make install，则会在100%停止进程（不安装任何内容）。这是输出：

然后突然完成它，没有安装任何东西！如果我再次运行make或make install，它会再次从头开始。请注意，没有CUDA就不会发生这种情况。
为什么会这样？
答案 0 :(得分：0)
cmake在安装构建库时遇到问题，因为我没有删除安装位置中的先前对象。一旦我手动删除它们就解决了问题（即使我认为make install可能会覆盖它们）。
