Title: Maps and different CPUs
Post by: Doctor J on March 08, 2008, 07:20:09 am

Are the maps compatible across OS/architecture?  I'm attempting to get UFO:AI 2.3 installed on three different computers in my household:

1) OSX/  Intel           [dual core]
2) OSX/  PowerPC G5 [64 bit]
3) Linux/ PowerPC G4 [32 bit]

Well, wouldn't you know it: i somehow chose to start the install on the slowest machine.  Compiling the executable was done in a reasonable amount of time, but the making of the maps has been running for two days now.   :'(

So will there be endianess issues or whatever if i just do this on the faster machine from now on?

you can load them on every other arch, yes

but the problem is, to also be able to play multiplayer you should use a intel 32bit cpu to compile the maps - otherwise the checksums will differ (due to different floating point precisions)

I have an Intel C2D, but I run WinXP 32bit. Does that count as "using a 32bit CPU"?

I have a problem with checksums. I made some tiles for random map assembly with XP64 (Athlon 64 Dual). I cant test the assembly because Im getting "ERROR: CM_InlineModel: bad number". Next I switched to my 32 bit XP, recompiled all the tiles and tried to play the assembly still getting the same error exept some times I get error for something like "Index Overflow". This is with 2.2 release.

22 bytes? i suppose your upload is broken

please attach them to the forum instead of using those - "wait-1-year-to-download-the-stuff"-hosters ;)
