To compile and use the SDL with Open Watcom you will need the following: |

- Open Watcom compiler. I used version 1.5. The environment variables |

|
- Open Watcom compiler. I used version 1.8. The environment variables |

PATH, WATCOM and INCLUDE need to be set appropriately - please consult |
|
|
the OpenWatcom documentation and instructions given during the |
|
|
installation of the compiler. |
|
|
My setup looks like this in owvars.bat: |
|
|
set WATCOM=C:\watcom |
|

set WATCOM=C:\dev\ow18 |

set INCLUDE=%WATCOM%\h;%WATCOM%\h\nt |
