[Qt-interest] How do I tell with qmake whether system is 64 or 32-bit?

I don't think there's a way to detect it explicitly from within a qmake
environment.  We typically pass it in as a configuration flag, and then
reference that setting within the *.pro files (e.g., "CONFIG+=32_dll").

A simple Python script can detect/configure your environment, set flags
appropriately for the qmake execution, and then launch 'qmake' for you with
the settings.  Under Windows, there are environment variables available that
indicate 32- or 64-bit OS; Linux will report the architecture using the "uname
-m" command (e.g., "i686" for 32-bit, "x86_64" for 64-bit).  The Mac doesn't
really have a distinction.

There are ways to do it if you really need it.  :)

 We can't all be architects. Some of us excel at building from the blueprints.
