libDGL is a "retro coding" C library aimed at MS-DOS VGA Mode 13h game development. It targets 486 DX2 systems as a baseline for performance.
The project is developed with Watcom C 10.0b and Borland Turbo Assembler 4.0.
Because it's fun.
If you were looking for something for "retro" MS-DOS game development that is fully featured, really performant and bug-tested that's ready right now, have a look at Allegro 3.x or possibly 4.x depending on what hardware you're targetting.
This library is currently under early development and is lacking many things and probably chock-full of bugs.

You can use
WMAKE to build using the included
To build the library:
> wmake target_config=debug build ; debug build > wmake target_config=release build ; release build
DGL.LIB in the project directory.
To build and run the (incomplete) test suite, look under the "TEST" directory. There you will
find a separate
MAKEFILE which assumes that you are running
wmake from that directory and
DGL.LIB has already been built.
> cd test test> wmake run ; run test suite test> wmake debug ; run through WD debugger
