How can I get VS 2010 to run more than one C++ compile process at a time? I mean building object modules in parallel; I\'m not interested in building more than one project a

Answer 1

Here is what I did

1) Go to Tools->Options than under "Project And Solutions"->"Build And Run" for me it had the number of cores. Although at first i thought this was all i needed to do but it isnt

2) Right click your project and select properties. Under "configuration properties"->"C/C++"->"Command Line" enter /MP4 where 4 is the number of cores you have. You'll get a warning about flags not being compatible so we have another step

3) Go to Under "configuration properties"->"C/C++"->"Code Generation" there is "Enable minimum rebuild". Change that to no.

Rebuild and you should see multiple CL processes in your task manager.
