It depends on what version of GNU make you're using, and the platform you're using it on. If you're using something near to the latest version, then it will run 10 jobs: all the submakes will communicate and ensure that no more than 10 jobs between them all. This will only work on POSIX-like systems; there's a set of POSIX features that the configure script checks for to decide whether make can do this or not. Earlier versions of GNU make will run up to 10 jobs in the top-level make, but will invoke all submakes with, essentially, -j1. -- ------------------------------------------------------------------------------- Paul D.
