The libusb-win32 package provides support for gcc/mingw but does not provide any integration with MSyS. This is the goal of this folder. Simply download the latest libusb-win32 package from http://libusb-win32.sourceforge.net/ and uncompress it. Copy the folder where you are reading this documentation into the libusb-win32 package: libusb-win32-0.1.12 +- bin +- examples +- include +- inf +- lib => +- libusb-win32 Go to the libusb-win32 folder and run ./install.sh within MSYS. That's all! Now, you have the libusb-win32 package useable with MinGW thru libusb-config and PkgConfig. For cross-MinGW, you may want to give a prefix to install.sh: PREFIX=/prefix ./install.sh --- Romain LiƩvin, Kevin Kofler
