Getting lots of these (link to Travis log):

CMake Warning at cmake/Macros/FindQt5Extra.cmake:7 (find_package):
  By not providing "FindQt5Multimedia.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "Qt5Multimedia", but CMake did not find one.
  Could not find a package configuration file provided by "Qt5Multimedia"

  Add the installation prefix of "Qt5Multimedia" to CMAKE_PREFIX_PATH or set
  "Qt5Multimedia_DIR" to a directory containing one of the above files.  If
  "Qt5Multimedia" provides a separate development package or SDK, be sure it

@willjp stumbled upon this issue in the Qt.py project: https://github.com/mottosso/Qt.py/issues/149

Is this still an open issue, Fred? If so, I'd be happy to lend another hand here. By which I mean, I'd have to lend another hand here. Our downstream project requires PySide2 bindings for various optional Qt dependencies that appear to have been skipped (namely Qt5Help, Qt5Multimedia, and Qt5Svg).

I'm intimately familiar shudder with the PySide2 CMakeLists.txt logic responsible for dependency detection. I note that the Ubuntu PPAs you've leveraged to install the full-stack version of Qt 5.6.2 appear to provide the necessary dependencies, which is nice. Presumably, either:

Is this something I should plumb deeper into? 🚽

I recently restructured the README.md to make it easier to digest. I extracted the modules lists from each build for Ubuntu here: https://github.com/fredrikaverpil/pyside2-wheels/blob/master/UBUNTU.md

I think this issue can be closed, but please do have a look.

I just read the intro readme, but wow, that's one hell of a cool project!

Are you using PPAs or are you building Qt from source there? It's a bit short term to use the PPAs, I've found. Stephan's PPA for Trusty has recently had the QtUiTools module removed as Qt Creator doesn't build anymore on Trusty: https://github.com/fredrikaverpil/pyside2-wheels/issues/74#issuecomment-323589778

I'm co-authoring another project in which I build Qt5.6 and PySide2 (5.6 branch) from source. You may be interested in doing the same to make sure you don't get issues from PPAs, such as that one. See here: https://github.com/fredrikaverpil/pyside2-wheels/issues/80

In this project, I use PPAs, just to provide a sane way of getting up and running with PySide2. It's not an ideal solution, as you know - but the quickest one I've found.

Aww, shucks! It'll be even cooler when it actually works. </longform_sigh>

Thanks to your Sisyphean efforts, we're considerably closer than we were a week ago. It feels like a year.

Are you using PPAs or are you building Qt from source there?

PPAs, for the moment. Incumbent laziness is our primary strength and weakness. You can view our ad-hoc brute-force Python 3.5 + Ubuntu 16.04 shell script installer, if you have a stiff stomach. As the familiar term "shell script" implies, it's pretty... not pretty.

We eventually intend to maintain a proper PPA or post-PPA snap. The current installers are only to get us over the short-term hump. Because grad student whinging knows no borders.

It's a bit short term to use the PPAs, I've found. Stephan's PPA for Trusty has recently had the QtUiTools module removed as Qt Creator doesn't build anymore on Trusty:

That's... really good to know. I'm thankful that he's at least attempted to preserve Qt for obsolete Ubuntu LTS releases. But still. Not good.

I'm co-authoring another project in which I build Qt5.6 and PySide2 (5.6 branch) from source.

Right. I briefly noted that. Would you be interested, perhaps, in extrapolating your existing work for us into a full-fledged PySide2 PPA or snap? Thomas Pietrowski's competing PySide2 PPA is functionally broken in numerous ways – and he's unresponsive on GitHub. ...that never helps.

I assume the only sane answer is: "Interested, but unwilling unless you direct deposit into my totally legit Nigerian bank account." That's my answer, too!

Absolutely. But that's also defining a healthy human being. 😉

I actually imagine it not being too difficult to do that on Ubuntu/Debian the only thing changing is the yum install (into apt-get install) for the prerequisites. And those apt-get install packages are (quite unexpectedly) provided by the Qt docs.

I'd be happy to help you out any way I can. But I can't take on more projects...

It's at this point I alway struggle not to mention considering PyQt5 (sorry). It's pip-installable and just works. If you use conda, you can just conda create -n myenv python=3.5 pyqt=5.6 and you're done.

It's such a shame that we are now discussing a new PPA when we should probably re-write setup.py ourselves instead to solve all of our problems by publishing portable (but unofficial) wheels on PyPi. But building everything from source is actually simpler. ðŸ˜
