GCC/Make Build Time Optimizations

Question

We have project which uses gcc and make files. Project also contains of one big subproject (SDK) and a lot of relatively small subprojects which use that SDK and some shared fra

Answer 1

If you have a LAN with developer machines, perhaps you should try implementing a distributed compiler solution, such as distcc.

This might not help if all of the time during the build is spent analyzing dependencies, or doing some single serial task. For the raw crunch of compiling many source files into object files, parallel building obviously helps, as suggested (on a single machine) by Nathan. Parallelizing across multiple machines can take it even further.
