C++ – How to utilise all the cores for nmake


I just got a new quad core computer and noticed that nmake is only using 1 process.

I used to use make which had the switch -j4 for launching 4 processes. What is the nmake equivalent?

Based on the information below I have been able to add a command to my qmake project file:


Which effectively did it for me. Many thanks.

Another generic, non-Qt-related way to tell nmake to use all the cores is to set environmental variable CL to /MP:

set CL=/MP

will use all the CPU cores.
