[Qt-interest] building both 32 and 64 bit Windows Qt app on a 32 bit machine with Visual Studio?

[Malyushytsky, Alex]

I am using qt-vsaddin-collection-2.1.2.exe which allows to use multiple versions QT3 and Qt4 on the same time.
With it you can chose which version of QT should be used for current build.

Few comments:
1. It allows to use as many QT versions as you want, including Qt3 (+)
2. There is no way to associate usage of specific version to the configuration. You have to manually set proper active QT version before you build another configurations in VC (-).
3. This add-in was distributed under commercial license, so it might be legal issues to use it if you did not have one (-).
4. It is not supported anymore ( together with Qt3 ).


Regards,
   Alex

You can also generate two *projects*, one for each bitness, and build
them within a single solution...
