Building DOOM with scratchbox2

First, follow the tutorial ScratchBox2_cross_compiling_with_SDL to set up the cross compilation environment.

Next, download the sdlDOOM source code:

wget http://www.libsdl.org/projects/doom/src/sdldoom-1.10.tar.gz
cd sdldoom-1.10

Now run scratchbox2 with the webos / pre mapping file:

$ sb2 -M /srv/preware/cross-compile/staging/mapping-armv7

You will get a different prompt indicating you are in a scratchbox shell, like:

[SB2 mapping-armv7 armv7] $

Run:

./configure --with-sdl-prefix=/usr/local
make 

Build should complete successfully with no problems. Download a DOOM shareware WAD:

wget http://www.libsdl.org/projects/doom/data/doom1.wad.gz
gunzip doom1.wad.gz

Copy the DOOM program binary and wad to root's home directory on the pre:

scp doom doom1.wad  root@pre:

SSH to the device (novaterm would also work to get there, or an on-device terminal)

ssh root@pre

On the device, run DOOM:

./doom

Yay, it should now run. You may want to customize the code for better controls on the device.
