Just to be clear, GNU make is not multithreaded. It simply spawns multiple processes and lets them run in parallel. GNU make has no built-in capability to use multiple machines: conceptually it may be a straightforward extension but the effort needed to communicate between multiple systems over a network, send and receive results reliably, kill jobs when someone stops the main make process with ^C, etc. is FAR out of GNU make's current wheelhouse. You can get a very cheap implementation, if you're willing to live with many prerequisite configuration requirements such as a networked filesystem, SSH access that doesn't require a password, etc. by writing your own script to forward the job via SSH and setting the GNU make SHELL variable to point to your script. Luckily, if you are building C or C++ code someone has already done all the necessary work for you. I recommend you investigate the distcc package: https://code.google.com/p/distcc/ Cheers! _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
