在pkg-config中找不到opencv。

Question

使用cmake和cuda创建opencv，文件保存在

/usr/local/lib/python3.8/dist-packages/cv2/python-3.8/cv2.so

现在我正在尝试安装darknet，但是我得到了这个错误

在opencv搜索路径中找不到包pkg-config。

也许应该将包含opencv.pc的目录添加到PKG_CONFIG_PATH环境变量中。

No package 'opencv' found

Answer 1

因为，您是从源手动安装的。它应该在一个目录中或通过环境变量声明.pc文件。

man pkg-config

pkg-config retrieves information about packages from  special  metadata
       files.  These  files  are named after the package, and has a .pc exten‐
       sion.   On  most  systems,  pkg-config  looks  in   /usr/lib/pkgconfig,
       /usr/share/pkgconfig,     /usr/local/lib/pkgconfig     and     /usr/lo‐
       cal/share/pkgconfig for these files.  It will additionally look in  the
       colon-separated  (on  Windows, semicolon-separated) list of directories
       specified by the PKG_CONFIG_PATH environment variable.

只需确保已经安装了opencv，而不仅仅是将它的共享库复制到python。我希望默认安装将.pc文件放在/usr/local/lib/pkgconfig/中
