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

[Malyushytsky, Alex]

This  become interesting.
Could you clarify how "win32:contains(QMAKE_HOST.arch, x86_64) {" can help to find which version of my application I am going to build.
If I do it from command line for MS compiler  line result depends on which compiler environment is set ( for example I normally build qt this way ).

Regards,

Alex

This with the *-64 approaches a complete solution for linux and windows.
Now we just need that mac guys to come along with their solution, although this might be handled by -64 as well.

Sounds like something I'll sum up on my blog.
