One way to do this is to create higher level makefiles with targets from several directories. This reduces the number of bottlenecks.
This is how I structure my own code and I can maintain a steady number of jobs over several build machines this way. This will also help to bring distributed building to ON. Ian _______________________________________________ tools-discuss mailing list [email protected]
