A Win32 inspired API/wrapper over Xlib/X11 for Linux and Unix machines.
Debian based systems require the following libraries:
sudo apt-get install libx11-dev libxft-dev
You can use standard ./configure to build the static library and tests.
./configure
make
make test
This will create a libw32x.a library and build a sample app that utilizes the library.
Alternatively, CMake files are provided but they may not necessarily be up to date.
