make on multiprocessor machines

2006-09-07 Thread Andreas Höschler
Hi all, we tried the -j option of make for the first time to speed up builds of GNUstep projects on multiprocess machines. We are trying this on a T2000 with 6/24 cores. I get the following error: -bash-3.00$ make -j 24 Making build-headers for framework SRFoundation... Creating

At the moment it's not really possible to make 'make -j' work because gnustep-make supports the before-all after-all before-xxx after-xxx (and similar) targets. They are implemented by using the order of prerequisites for rules, but in a parallel build you can't rely on that. :-( There might

There might be ways out by using new make features, but at the moment you shouldn't expect 'make -j' to work. I think to speed up compilation, supporting PCH would be an easier task. I need to get my hands on a GCC version = 3.4.x ;-) So we should concentrate on machines with good single

I've been moving some of the stuff from the main website to the Wiki (since I got access this afternoon) and I want to make sure this is the direction I'm supposed to be working. Most of it I'm just copying and pasting to the wiki and making modifications which I think are acceptable (like
