I was wondering what unsermake was.... I suppose we could create an unsermake generator in cmake, and that could be used to do the parallel builds. >The actual distribution over a compile farm can be done with distcc or >with the KDE fork of it, icecream (which has a nice GUI, and an easier setup >AFAIK). However, one idea we are thinking of now, is something like this: cmake -E WaitForSemaphore semaphore_file <some cmake command (could be a link, could be moc, or anything else)> cmake -E ReleaseSemaphore semaphore_file Then you could use this to serialize any part of the build independent of the build tool being used. It would be done with some sort of target or global property that could be used to insert those commands around any command that needs to be done in a serial mode. Then the semaphore could be initialized with 1 to achieve full serialization, or a higher number to allow up to N of the group to run at once. That way cheap tasks (distributed compilation) could have full parallelism, medium-cost tasks (moc?) could have a lower level of parallelism, and expensive tasks (linking) could have full serialization. -Bill _______________________________________________ Kde-buildsystem mailing list [email protected] https://mail.kde.org/mailman/listinfo/kde-buildsystem
