How do I deploy a Python PyQt5 Application to an embedded Linux?

Question

I've written a Python3 application which uses PyQt5 for the GUI, it runs fine on every desktop system. Now I would like to run this on an embedded linux (specifically: Yocto BSP) which is delivered by the hardware manufacturer. Since there's no PyQt5 but a qt5 and python3 package running on the BSP, I would like to (somehow) make a standalone executable of the application. Plus I'm not experienced with writing bitbake recipes and creating a custom BSP and have not found any existing PyQt5 recipes.

What I've tried so far (and did not succeed):

• Make a standalone executable with nuitka, cx-freeze, pyinstaller (compiled on a similiar arm platform)
• Use pyqtdeploy to convert python into c++ source code, then compile it by using the supplied build-environment. I did a static compile of the pyqt5 and sip packages and everything compiles just fine, but make reports undefined references (linker errors) which I cannot resolve (as I'm not very familiar with c++).

Now what's the best approach to let a python/pyqt5 application run on an embedded linux system with very limited packages?

Unfortunately not the answer you'd like... Personally, I'd look into adding PyQt5 to my own layer. (And later on submitting it to a suitable open layer). There's a python-pyqt recipe in meta-oe that //might// be of some help; though there are differences between Qt4 and Qt5 in OpenEmbedded / Yocto. – Urticaceous

For the newcomers, since Release branch Thud of the Yocto Project, you will find what you need under the name: python3-pyqt5. – Twandatwang

First you should get the meta of qt5: https://github.com/meta-qt5/meta-qt5 Then modify the local.con and you-image.bb to make the qt5 can be compiled into the image.
