I have installed some libraries with Homebrew but if I use pkg-config it does not find them because there are missing .pc files.
For example, if you do:
brew install opencv
and, after it is installed:
pkg-config --libs opencv
I get this error:
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
This error is caused because Homebrew does not create any opencv.pc
.
Is there a way to configure Homebrew to create the .pc files so that all packages installed with brew can be found by pkg-config?
Best Answer
Check with
brew ls opencv
that there is noopencv.pc
installed. I tried it and I have one. If you don't get one, then there is a bug in the package.Otherwise, check that you are using the correct Homebrew
pkg-config
. Check withwhich pkg-config
andls -l $(which pkg-config)
where it is coming from.
