from dandev37: Here's a step by step from a clean install to successfully setup MinGW and build libusb-1.0 and stlink for MS Windows. Hopefully this helps someone. 1. Install MinGW and MSYS to C:\MinGW with the graphical installer from http://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download and add these packages: mingw32-base mingw-developer-toolkit 2. Add C:\MinGW\bin to your path. Note: a user reports she had to use c:\MinGW\msys\1.0\bin 3. Create the C:\MinGW\msys\1.0\etc\fstab file to mount C:\MinGW as /mingw as per http://www.mingw.org/wiki/MSYS: #Win32_Path Mount_Point c:/mingw /mingw 4. Download these three glib, pkg-config, pkg-config-dev archives and extract contents to C:\MinGW http://win32builder.gnome.org/packages/3.6/glib_2.34.3-1_win32.zip http://win32builder.gnome.org/packages/3.6/pkg-config_0.28-1_win32.zip http://win32builder.gnome.org/packages/3.6/pkg-config-dev_0.28-1_win32.zip 5. Download latest libusb-1.0 source from git://git.libusb.org/libusb.git and build (prefix as per http://www.mingw.org/wiki/MSYS) ./autogen.sh ./configure --prefix=/mingw make make install 6. Repeat for stlink source from https://github.com/texane/stlink ./autogen.sh ./configure --prefix=/mingw make make install 7. Enjoy the fruits of the stlink developers.
