Qt libraries wont install

  • so im using windows 7 64 bit on my laptop

    i downloaded:

    • qt-creator for windows
    • Qt libraries 4.8.6 for Windows

    and all is fine i'm ready to go
    installed qt-creator

    but then when i install Qt libraries it asks for my c:\minGW32 , i neither have minGW nor use a 32 bit OS , how do i solve this ?

    • You need a compiler which matches your copy of Qt. If you downloaded "Qt libraries 4.8.6 for Windows (MinGW 4.8.2, 328 MB)", then you need to use the MinGW 4.8.2 compiler.
    • "32" here refers to the bitness of your compiler and libraries, not your OS. You can run 32-bit programs on a 64-bit OS.

    Anyway, if you are just starting, I recommend that you install Qt 5.3 instead of Qt 4.8.

    The easiest way is to download "Qt 5.3.1 for Windows 32-bit (MinGW 4.8.2, OpenGL, 735 MB)" -- this package contains Qt, Qt Creator, and MinGW.

  • im really sorry for the delay

    are there major differences between qt 4 and 5 ?

    In general, Qt 5 has better performance and features. It also dropped support for older, obsolete functions.

    Qt 5 is currently being actively developed -- new features are being added and bugs are being fixed.

    Qt 4 is still being maintained and important bugs are still being fixed, but much less effort is being spent on it than Qt 5. It is no longer getting new features.
