Need help with Qt x64 for Windows



  • I was shocked to learn that there are no Qt binaries for x64 Windows. My understanding is that I have to build them myself.

    I've looked at the instructions on "this post":http://developer.qt.nokia.com/wiki/How_to_build_64bit_Qt_for_windows which leads to "this instruction page.":http://www.holoborodko.com/pavel/2011/02/01/how-to-compile-qt-4-7-with-visual-studio-2010/

    I got through a large portion of the build (for 4.8.0), but it fails when openglax.exe fails to run: "The procedure entry point ?qt_painterPathFromVectorPath@@YA?AVQPainterPath@@AEBVQVectorPath@@@Z could not be located in the dynamic link library QtGui4.dll."

    I don't even know where to start on diagnosing this. I'd followed some (presumably out of date?) comments at the bottom of the instructions page, and installed Windows Server 2003 R2 Platform SDK.

    This is on Windows 7 x64 with Visual Studio Pro 2010.

    Any guidance would be greatly appreciated!



  • Nevermind... requesting help made everything work.

    Actually, I'd just installed the Windows 7 SDK, I think that's what may have done it.



  • I recommend installing the QtSDK (even if you are not using Qt Creator). You can then use the QtSDK Maintenance Tool to install Qt versions selectively. It does offer 64-bit Windows packages AFAIK. Just make sure to select the correct VS version.
