[solved] Need help running my .exe and deploying app--MinGW 4.8 32 bit



  • Hello, First my goal we to get my app running on another Windows 7 PC, but then I discovered that the .exe will not even run on the PC where I do the development, so I need help with both of these issues. Here is what I have:

    Windows 7 Enterprise
    Qt Creator 3.0.1
    "Based on Qt 5.2.1 (MSVC 2010, 32 bit)"

    From my kit:
    Compiler: MinGW 4.8 32 bit
    Qt version: Qt 5.2.1 MinGW 32bit

    I am using Qt Creator, not Visual Studio. When I try to start the .exe, I get "The program can't start because Qt5Core.dll is missing from your computer..." I have searched and found many answers, but don't know which applies to me. Please help. For now I will start copying the dll's it complains about into my .exe folder.
    Thanks
    Ron

    Hi,

    Have a look this "wiki entry":http://qt-project.org/wiki/Deploy_an_Application_on_Windows for deployment.



  • Thanks SGaist, I hadn't found that page. I got it working just by copying the DLL's that it complained about from the Qt installation into my release folder, was only 9 of them. I suppose with the Digia-licensed version, you can build an exe with no dependencies, is that how it works?

    Thanks again.

    It depends on what you mean by dependencies (only Qt ?), but you can build a static version of Qt and also your application as static.



  • You mean only with the fully-licensed version, right? Not with LGPL.

    I just mean dependencies on the Qt libraries. I'm not using any other DLL's or anything. By static binding, does this mean a stand-alone EXE?

    I am not a lawyer so for licensing issues you should either contact one or talk with Digia directly.

    Yes, you'll only have a dependency on VS runtime but it's normal and it's better to keep it so.
