Running executable on Windows fails

First of all thank you for your work, having a GitHub action to install Qt in a cross-platform way is a lifesaver. I’m currently in the process of switching CI for the qxmpp project over to GitHub actions, and Linux and OS X are building and running their test suite just fine.

On Windows I have been able to compile the test suite, but running it fails with Exit code 0xc0000135. Unless I’m mistaken this means the dynamic linker is not finding a DLL, which surprises me as your action does add Qt5_DIR/bin to PATH.

An example failing run:

Do you have any suggestion as to how to debug this?

often having the Qt bin in your path is not enough because that only solves the .dll loading of linked libraries. These two other variables solves the dynamic loading issues.

I had to set the following variables in order to make my application run (loading qt plugins and qml)

        set QT_PLUGIN_PATH=%Qt5_DIR%/plugins
        set QML2_IMPORT_PATH=%Qt5_DIR%/qml
