I have installed pkg-config and libusb through brew
Now if I do
pkg-config --cflags --libs libusb
I get below message
Package libusb was not found in the pkg-config search path. Perhaps you should add the directory containing `libusb.pc' to the PKG_CONFIG_PATH environment variable No package 'libusb' found
So I followed this post and did
export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/usr/local/Cellar/libusb/1.0.20/lib/pkgconfig"
But I still have the problem. What am I missing?
I am using MAC OSX El Capitan
Just run:
pkg-config --cflags --libs /usr/local/Cellar/libusb/1.0.20/lib/pkgconfig/libusb-1.0.pc
I have the the same problem. This work for me (Ubuntu):
sudo apt-get install libmagickwand-dev
The problem appears to be that homebrew installs libusb with the -1.0 appended to the package and file names. So:
pkg-config --cflags --libs libusb-1.0
will find it, while:
pkg-config --cflags --libs libusb
won't. Since many ./configure and other scripts are looking for it without the -1.0 appended, they fail. To me, this looks like a bug in the homebrew package. Manually creating a non-1.0 named version worked for me, but it's not a very elegant solution.
