Buiding both 32 and 64 bit windows on 64 bit windows machine



  • This seems to be asked a lot, but I haven't found a good answer, it seems.

    I'm running the Windows 7 x64 Build Environment console.

    If I use:
    configure -debug-and-release -platform win32-msvc2010

    does it build 32 bits or 64 bits by default?

    If I want to build 32 or 64 bits explicitly do I put something on the command line for -arch? seems my only choice is "windows" but that's not really an architecture....

    I tried -arch x86_64 but got a link error in the qatomic......code.

    Thanks

    Rick
