I need to generate a 32 bits version of my application however I am compiling on a 64 bits OS. I\'m looking for a way to make QMake to generate both 32 and 64 bits versions

Answer 1

Make use of win32: in front of each command you would like be run for win32 architecture only. Or can use a scope as

win32 {
     SOURCES += paintwidget_win.cpp
 }

Also, you may refer to the architecture win32 or x64 with the ($Platform) MSDN macro for Visual Studio.
