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:
QMAKE_CXXFLAGS += /MP
Which effectively did it for me. Many thanks.
According to MSDN, there's no such option for
You can however make the compiler build multiple files in parallel by using the
/MP option with the VC++ command line compiler and passing multiple files at the same time:
> cl /MP a.cpp b.cpp c.cpp
However note that most Makefiles don't call the compiler like this - they usual invoke the compiler separate for each individual source file, which would prevent the
/MP option from doing anything useful.
Another generic, non-Qt-related way to tell
nmake to use all the cores is to set environmental variable
set CL=/MP nmake
will use all the CPU cores.
