Deployment win10

  • This project is a pure C++ code, there is no qt code in it.

    First I run my code in release mode. Then at release folder I found the .exe file. Then I search for QT 5.15.2 (MinGW 8.1.0 64-bit) and I write


    I get the following code.

    Usage: windeployqt.exe [options] [files]
    Qt Deploy Tool 5.15.2
    The simplest way to use windeployqt is to add the bin directory of your Qt
    installation (e.g. <QT_DIR\bin>) to the PATH variable and then run:
      windeployqt <path-to-app-binary>
    If ICU, ANGLE, etc. are not in the bin directory, they need to be in the PATH
    variable. If your application uses Qt Quick, run:
      windeployqt --qmldir <path-to-app-qml-files> <path-to-app-binary>
      -?, -h, --help              Displays help on commandline options.
      --help-all                  Displays help including Qt specific options.
      -v, --version               Displays version information.
      --dir <directory>           Use directory instead of binary directory.
      --libdir <path>             Copy libraries to path.
      --plugindir <path>          Copy plugins to path.
      --debug                     Assume debug binaries.
      --release                   Assume release binaries.
      --pdb                       Deploy .pdb files (MSVC).
      --force                     Force updating files.
      --dry-run                   Simulation mode. Behave normally, but do not
                                  copy/update any files.
      --no-patchqt                Do not patch the Qt5Core library.

      --no-compiler-runtime       Do not deploy compiler runtime (Desktop only).
      --webkit2                   Deployment of WebKit2 (web process).

      --angle                     Force deployment of ANGLE.

                                   relative: paths of the target files, relative
                                             to the target directory
                                   mapping:  outputs the source and the relative

      [files]                     Binaries or directory containing the binary.

    Then I go to the release file folder. Then I run the following command:

    windeployqt.exe eval.exe

    I get the following message:

    C:\Qt files\.....\release>windeployqt.exe eval.exe
    C:\Qt files\....\release\eval.exe 64 bit, release executable
    C:\Qt files\...\release\eval.exe does not seem to be a Qt executable.

    I have no idea what could be the problem. I would really appreciate if you could help me solve my problem.

  • @bence as mentioned in the question, the application you are trying to deploy is purely c++ without using qt libraries.
    hence windeployqt giving correct message

    eval.exe does not seem to be a Qt executable

    There is no qt run time libraries to link against.

  • Is there any other way to run the pure c++ code?

  • Moderators

    windeployqt is for deploying Qt applications, as its name suggests. So, it can't be used to deploy a non-Qt app.

    @bence said in Deployment win10:

    Is there any other way to run the pure c++ code?

    You don't need any special tools for that. Just copy and paste the required MinGW DLLs into the same folder as your app.

    If you try to run your app but a required DLL is missing, you will get a pop-up dialog that tells you which DLL it needs.
