Hi,
I've been trying to get SDLQuake working on my Raspberry Pi computer but have run into an annoying issue. I've successfully got the program to compile and run however when trying to create a new game I receive a segmentation fault.
I've done some digging and it appears to be caused when trying to load progs.dat. From what I've found on google progs.dat is the compiled game logic in QuakeC. Obviously a very important file, but fails to load when trying to start a new single player or multiplayer game.
This is the code base I'm using: http://www.libsdl.org/projects/quake/
and my edited makefile: SDLQuake R-Pi Makefile - Pastebin.com
I did a little stack trace with gdb which gave me this:
Which lead me to the sys_sdl.c file and this function:
I don't understand why it's failing when it seems to be loading other files perfectly fine.
Any assistance on getting this working would be awesome
. I can read C and sort of understand what's going on but I don't know the inner workings of the Quake engine (I'm trying to learn as much as I can 
). The Raspberry Pi for those that don't know is a small cheap ARM based computer based on ARMv6 with hardware floating point support. I'm trying to get this to run on Raspian Linux.
Thanks.
