- tested on OpenVMS 8.4 Alpha 

1) PREPARATION 
---------------

### We need a compiler first for AXP OpenVMS  
### We will be using a secondary slave IDE disk DQB1 in our example 
### so adjust accordingly 
 
$ set def DQB1:[000000] 
$ create/directory [.DATA]
$ create/directory [.DATA.COMPILER] 

$ set def DQB1:[000000.DATA] 

### Upload CURL.EXE,  MMK.EXE and UNZIP.EXE via SFTP or FTP to your OpenVMS system  

https://astr0baby.online/AXP/OpenVMS/TOOLS/curl.exe
https://astr0baby.online/AXP/OpenVMS/TOOLS/unzip.exe
https://astr0baby.online/AXP/OpenVMS/TOOLS/mmk.exe

### Place it in DQB1:[000000.DATA] 

$ curl :== $DQB1:[000000.DATA]curl.exe 
$ unzip :== $DQB1:[000000.DATA]unzip.exe 
$ mmk :== $DQB1:[000000.DATA]mmk.exe  

2) COMPILERS 
-------------

### Download the Compiler ZIPs to your VMS system 
$ set def DQB1:[000000.DATA.COMPILER] 
$ curl http://astr0baby.online/AXP/OpenVMS/TOOLS/C_Compiler_73.zip -o C_Compiler_73.zip 
$ curl http://astr0baby.online/AXP/OpenVMS/TOOLS/CXX_Compiler_73.zip -o CXX_Compiler_73.zip 
$ unzip CXX_Compiler_73.zip 
$ unzip C_Compiler_73.zip 
$ @sys$update:vmsinstal  cc073 DQB1:[000000.DATA.COMPILER] options N 
$ @sys$update:vmsinstal cxx073 DQB1:[000000.DATA.COMPILER] options N

### delete the extracted archives 
$ del *.a;1 
$ del *.b;1
$ del *.txt;1 

### Register the C and CXX licenses
### Hint :) use the pakgen dude 

$ @SYS$UPDATE:VMSLICENSE


3) BUILDING SDL 
----------------

### 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 
$ @build.com 
$ DEFINE LIBSDL DQB1:[000000.GAMES.SRC.SDL.SRC] 
$ DEFINE SDL DQB1:[000000.GAMES.SRC.SDL.INCLUDE] 


$ set def dqb1:[000000.GAMES.SRC.SDL_MIXER]
$ @configure.com 
$ @build.com 
$ DEFINE LIBSDL_MIXER DQB1:[000000.GAMES.SRC.SDL_MIXER] 

$ set def dqb1:[000000.GAMES.SRC.SDL_NET]
$ @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 

DEFINE LIBSDL DQB1:[000000.GAMES.SRC.SDL.SRC] 
DEFINE SDL DQB1:[000000.GAMES.SRC.SDL.INCLUDE] 
DEFINE LIBSDL_MIXER DQB1:[000000.GAMES.SRC.SDL_MIXER]
DEFINE LIBSDL_NET DQB1:[000000.GAMES.SRC.SDL_NET] 

4) BUILD DOOM/HEXEN 

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

$ set def DQB1:[000000.GAMES.SRC.PRBOOM] 
$ @configure.com
$ @build.com 
$ create/directory DQB1:[000000.GAMES.DOOM] 
$ copy DQB1:[000000.GAMES.SRC.PRBOOM.SRC]DOOM.EXE DQB1:[000000.GAMES.DOOM]
