after building libpng, pcre, and expat, and changing the header path from /opt to /usr in your xcodeproj file (not using fink here), i can ALMOST get it to compile. the error i get now is "Unknown byte order type" thrown by a preprocessor directive in q_shared.h. I am doing this on a PPC G4 with the latest Xcode.

that's cos of some code that (VVD?) added to 'streamline' byte ordering

just change the define in q_shared.h to be bigendian as you are on PPC

Okay, now it gets to cmd.c and misses a file. Spotlight doesn't find the file. I noticed that the project file for Xcode hasn't been updated in six months, is this gonna be a serious obstacle?

net.c now

i remember that i couldn't do this at the time as xcode doesn't support architecture specific define flags

- In snd_mix.c:
I had to comment out both of these lines in order to get the file to compile.

//void Snd_WriteLinearBlastStereo16 (void);
#ifndef id386
static void Snd_WriteLinearBlastStereo16 (void)

//void SND_PaintChannelFrom8 (channel_t *ch, sfxcache_t *sc, int endtime);
#ifndef id386
static void SND_PaintChannelFrom8 (channel_t *ch, sfxcache_t *sc, int count)

- Deleted xml_test.c from project file

Now it's getting to the linking stage and then failing with about a million undefined symbols, the first of which is _Q_atof
