Multithreaded compiler

[zerver]

I just found the command line switch /MPx for visual studio 2005 (x = number of CPU).
Fucking awesome compile speed on my dual quad xeon. A full "rebuild all" in 3 minutes.
I'm so sorry I did not find this option sooner...

Is there a similar option for gcc/scons ?

[imbaczek]

scons -j#

cmake depends on make, which doesn't support -j on windows. works fine on posix.

btw can you write up some instructions how to compile in vs 2008 with java skirmish ai support? links to vclibs and such welcome ^^

[zerver]

Ah, very nice. Less than 4 minutes with gcc/scons.

I'm not sure about building the java skirmish AI. Will look into it.

Oh, by the way. Java AI build does not work for me with scons either.
If u can help me fix that, maybe I can do something with MSVC.

I modified the Sconscript file slightly to eliminate the file not found error, and instead get crash:

sorry, the first error is my fault. if you fixed it, please commit it, or i will do a fix.
the error you get now is most likely becasue of the awk you use.

use

awk.zip

gawk compatible awk for windows that works standalone

(extract it to your mingwlibs/bin/ folder), just overwrite the one that is currently there.

we have to include this one with the next release of mingwlibs.

tell me if you wont upload a fix for the first problem.
