[Qt-interest] How do I tell with qmake whether system is 64 or32-bit?

[Ben Swerts]

Hi Nikos,

For quite a few systems you can check the QMAKESPEC, as mentioned before.
For Windows, however, you'll need something else. We use this construct:

win32:contains(QMAKE_HOST.arch, x86_64) {
  LIBS += fmodex64
} else {
  LIBS += fmodex32
} 

Hope it helps,


	Ben
