Standalone wheel

[bjquinn]

Interested in seeing if there's an chance of getting standalone versions of the wheels. @leycec mentioned a --standalone option for setup.py in #44, don't know if that might be useful.

I forgot to write in that thread that --standalone is a dead end, unfortunately. It doesn't work. I've tried it. Like many other things in setup.py, it's been left there since the PySide(1) days. You can see for yourself what it does here: http://code.qt.io/cgit/pyside/pyside-setup.git/tree/setup.py?h=5.6#n1018

I'm guessing that the files which should be copied there are in fact not properly copied, perhaps similarly as in #44.

This (standalone wheels) is what everyone wants and it would be pure gold to have. Unfortunately, I don't have the time available for such a task.

By the way, if you're on Windows you can check this out: https://github.com/fredrikaverpil/pyside2-wheels/issues/69

Thanks! That accomplished what I was trying to do on Windows.

How is that different from standalone?

[fredrikaverpil]

What do you mean? Would you consider the Windows wheel standalone?

To me, it doesn't seem properly configured to be standalone even if it bundles a lot of the right stuff. I'm not sure it has everything bundled although it clearly has a lot more than the Linux/macOS wheels.

I don't know what might still be missing, but for me, setting the QT_QPA_PLATFORM_PLUGIN_PATH to the platforms folder under site-packages seems to work as well as setting it to C:\Qt\Qt5.6.2\5.6\msvc2015_64\plugins\platforms. And not setting it at all results in the error you referenced in #69, so it doesn't appear to be getting Qt libraries from anywhere else, and I don't have anything in any other environment variables pointing to anything for Qt. I don't know if there are features I'm not using or something, but I haven't run into anything yet.

It's possible that everything is properly bundled with the Windows wheel and that some configuration is missing to tell PySide2 where to find the DLL files. I found out about the QT_QPA_PLATFORM_PLUGIN_PATH and to me it seems like that was a workaround to achieve portability on Windows – but I only tested this with a couple of simple commands and would assume the wheel is not properly installed for portability without it (the environment variable). I have no idea what other things may be misconfigured (or not).

However, on Unix, wheels doesn't have any of the required Qt libraries bundled.
