This does not control it for command line xcodebuild. I am finding xcodebuild is always launching two cc1plus on my 2GB RAM laptop, each one using nearly 1GB and thrashing the VM. I have no choice but to use this machine for some work, and it can't take more memory.
(Note that the PBX_NUMBER_OF_PARALLEL_BUILD_SUBTASKS variable documented at http://developer.apple.com/tools/xcode/dec2002PBReleaseNotes.html no longer works either.)
Is there a way I can prevent xcodebuild from doing this?
(My best workaround at the moment is to wait for Xcode to thrash my machine then "kill -STOP" one of the cc1plus for while, then "kill -CONT" later on.) _______________________________________________
