XGKS is a level 2C implementation of the ANSI Graphical Kernel System (GKS) for use in a Unix environment with the X Window System. It supports the Fortran language binding and a C language binding based on the 1988 draft.

GKS is a basic graphics system for applications that produce computer generated two-dimensional pictures on line graphics or raster graphics output devices. It supports operator input and interaction by supplying basic functions for graphical input and picture segmentation and allows storage and dynamic modification of pictures. GKS is no longer under active development, but used in several existing graphical toolkits.

It is not expected that XGKS will gather any new users, but factoring it out simplifies the size and maintenance of some other packages.

sudo apt-get -y install libxgks-dev
