QML Plugin not loading on Windows #90

Closed JustinSteventon closed 6 years ago

JustinSteventon commented 6 years ago

I'm getting the following: QQmlApplicationEngine failed to load component qrc:/main.qml:4 plugin cannot be loaded for module "io.thp.pyotherside": Cannot load library C:\Qt\5.10.0\msvc2015\qml\io\thp\pyotherside\pyothersideplugin1.dll: The specified module could not be found.

The DLL exists in that location (alongside Python37.dll which it links to).

I followed the steps in the tutorial for building, including building Python and deploying the plugin. Everything was successful with a couple of exceptions:

  1. In qpython_priv.cpp I had to add a "constexpr" before "int argc = 1;": constexpr int argc = 1; wchar_t *argv[argc];
  2. In the Building For Windows section of the developers guide, step (6) should be "Hit Deploy to install PyOtherSide in your local Qt folder"

Looks like a very interesting tool. If it could be a little easier to install that would be great.

Turns out the problem was that I had to copy Python*.dll to my exe folder. Also my build using MSVC 2015 tools was somehow broken. Using the prebuilt libraries works though.

Been trying to build pyotherside on Windows with no success. Please advise. What Qt version should I use? What VS C++ (Express) Compiler version should I use? MSVC 2015?? 64bit or 32bit??

or better, is it possible to share your version of the build?

Please always try with the latest MSVC version (2017 as of this writing), the Community Editions are free for open source projects.
