### Setup MESA on OpenVMS 8.4 AlphaServer DS10 ### 

- Tested  PCI VGA card =>  Radeon 7500 

(ATI 102G012400 Radeon 7500 64MB DDR PCI DVI/VGA/RCA Video Graphics Card) 

- We are using a second slave IDE disk on dqb1 here so adjust accordingly 
- MPlayer works on DWMOTIF with Radeon 7500 card !

###
# Original MESA and LIBXMU packages are from http://nchrem.tnw.tudelft.nl/openvms/software2.html  

$ set def DQB1:[000000] 
$ create/directory [.MESA]

### Next we need to compile SDL with opengl support 
### Create WORKING SOURCE directory on your OpenVMS 

$ set def DQB1:[000000] 
$ create/directory [.GAMES] 
$ create/directory [.GAMES.SRC] 
$ set def DQB1:[000000.GAMES.SRC] 

$ curl http://astr0baby.online/AXP/OpenVMS/SRC/sdl.zip -o sdl.zip 
$ curl http://astr0baby.online/AXP/OpenVMS/SRC/sdl_net.zip -o sdl_net.zip 
$ curl http://astr0baby.online/AXP/OpenVMS/SRC/sdl_mixer.zip -o sdl_mixer.zip 

$ unzip sdl.zip 
$ unzip sdl_mixer.zip
$ unzip sdl_net.zip 

$ set def dqb1:[000000.GAMES.SRC.SDL] 
$ @configure.com opengl 
$ @build.com 
$ DEFINE LIBSDL DQB1:[000000.GAMES.SRC.SDL.SRC] 
$ DEFINE SDL DQB1:[000000.GAMES.SRC.SDL.INCLUDE]

$ @configure.com 
$ @build.com 
$ DEFINE LIBSDL_NET DQB1:[000000.GAMES.SRC.SDL_NET] 

### Please note that for any future builds using SDL includes and libs make sure 
### to set the environment variables

### BUILD DOOM with OpenGL support 

$ set def DQB1:[000000.GAMES.SRC] 
$ curl http://astr0baby.online/AXP/OpenVMS/SRC/prboom.zip -o prboom.zip 
$ unzip prboom.zip
