问题
How can I add a newly installed library's .pc file to pkg-config's path. In my experience this happens automatically, but not with recently installed opencv3 via homebrew.
Most of my libraries' .pc files are in /usr/local/lib/pkgconfig (including opencv), but not opencv3
The library opencv3 exists in /usr/local/cellar, and does have a opencv.pc in /usr/local/cellar/opencv3/3.1.0_4/lib/pkgconfig.
Now I need pkg-config to find it, but I think it makes more sense to add this .pc to an existing path rather than add a whole new path.
Is there a recommended process to add it? Thank you very kindly.
回答1:
I have noted the same. You can just specify a full path to a .pc file instead of using a PKG_CONFIG_PATH.
So, I tend to use this in bash and double up the dollars in Makefile since it avoids having to change anything when I upgrade:
pkg-config ... $(find /usr/local/cellar/opencv3 -name "opencv*.pc")
My method assumes that I don't keep multiple versions of hombrew package version lying around - which I do not anyway - YMMV!
