stgl is a terminal emulator for X which sucks more than the original st, but it's got neat fire effects!.
See config.h for font configuration, and the header of rendering.cpp for feel factor configuration.
In order to build stgl you need the Xlib header files and a libGL implementation. You'll also need GLM.
In order to run stlgl you will need a reasonably modern graphics card with OpenGL 4.5 support.
Edit config.mk to match your local setup (st is installed into the /usr/local namespace by default).
Afterwards enter the following command to build and install st (if necessary as root):
make clean install
If you did not install st with make clean install, you must compile the st terminfo entry with the following command:
tic -sx st.info
See the man page for additional details.
