我试图在RHEL7 docker映像中使用CUDA11.1构建OpenCV标记4.2，但遇到了一些问题。第一个问题/警告是：

   THRUST_COMPILER_DEPRECATION(C++14, pass -std=c++14 to your compiler);

这可以通过从

cmake/opencvdetecttcuda.cmake:265

中删除

--std=c++11

来解决。好吧，简单到可以处理这个警告。尽管使用cmake选项/define更改它会更好。无论是否有上述更改，

gpu_mat.cu

的编译错误都存在

然后，主要问题是

gpu\u mat.cu

正在发生的构建错误。这是我目前的CMake产品线。我尝试了很多不同的选择，在这一点上，我只是把所有的东西和厨房水槽都扔向它

我已经搜索了这些错误，但我想我的google fu在这方面很弱。我在Ubuntu18Docker映像中构建OpenCV 4.5.1w/CUDA时没有这些错误/问题。所以我完全错过了一些东西，已经为此工作了几天。我不知道下一步该怎么办。

感谢您的支持。

我看到了一些与您非常相似的构建错误，所以您并不孤单！我听说这与最近对centos 7的更改有关，它破坏了nvcc。希望很快就能修好。

据报道，RHEL/CentOS存在问题，现已解决

谢谢！这让我找到了答案。
