It is a good idea for custom maps. But doesn't solve the problem. Our prebuilt packages should be compatible. People download ~1.2G for the game then they should download again each map on each different servers they play on (at worst case)...

I have compiled the maps again, this time with more parallel jobs but the best I can do with a Core Duo with 4 GB RAM is 4,5 hours so far.

Though I still get different md5sums for the *.bsp files.

Sandro:
Current map compliler is mathematically unstable, so resulting .bsp depends on gcc flags used to compile it, CPU used, number of threads and other factors. So it is hopeless to get identical bsps with it.

Somebody tried to make a Java-based compiler, which theoretically should give identical results on every platform, if strategically peppered with strictfp modifier, but this work was abandonned long ago.
Or someone in future may be willing to rewrite the compiler into the fixed point  :P

we once used -ffloat-store - but it was slower: link

It is better than impossibility to play between different server and clients.
