I was able to get this working without much issue on Linux:
Code:
git clone https://github.com/VoidForce/QSprawl.git
cd ./QSprawl/Quake
make
./ironwail -basedir /path/to/sprawl_v1_1
(NB: spawl will not work with modified paks, so if you customized them, be sure to drop the vanilla id1 in the spawl_v1_1)
playing id1 levels with the spawl kit is a hoot, although the weapons enemies and movement are all clearly a bit mismatched, it's a lot of fun to mess around, and custom maps designed around these assets are sure to be a great time. Looking forward to what gets made!
