opencv - opencv_createsamples 中的链接问题

Question

我正在 NVidia/Cuda:7.5-cudnn4-devel-centos7 中设置 opencv 2.4.10 docker 容器。运行 make install 几乎完成，然后我得到这个错误:

[ 99%] Built target opencv_haartraining_engine

make[2]: *** [bin/opencv_createsamples] Error 1
make[1]: *** [apps/haartraining/CMakeFiles/opencv_createsamples.dir/all] Error 2
make: *** [all] Error 2

我能够让 opencv 2.4.10 在 CentOS 6 中与 CUDA 7.0 一起工作，但这个问题出现在 CentOS 7 和 CUDA 7.5 中。

Answer 1

我仍然不确定为什么这个步骤在这里是必要的，而不是在我的 CentOS 6/CUDA 7.0 设置中；我还感到惊讶的是，直到 make install 过程中才需要进行此修复，但解决方案很简单

清理

然后

安装
