Using /MP[processMax] option
More information about /MP[processMax] option here. Just add this flag to your spec file (%QIDIR%/mkspecs/win32-msvc*/qmake.conf).
processMax argument:
- (Optional) The maximum number of processes that the compiler can create.
- The processMax argument must range from 1 through 65536. Otherwise, the compiler issues warning message D9014, ignores the processMax argument, and assumes the maximum number of processes is 1.
- If you omit the processMax argument, the compiler retrieves the number of effective processors on your computer from the operating system, and creates a process for each processor.
Example: /MP2 (for dual core), /MP4 (for quad core)…
Using jom
In linux we do speed up with make -j4 or something like this. There is similar tool developed called jom, it can be downloaded from git here.
See also "jom's wiki page":jom
Precompiled packages can be found here.
The original announcement of jom can be found here:
