5 years ago It's not possible to build pyqt5 as no source distribution is provided: there's nothing to build from. The maintainers (Riverbank) only provide wheels built for Windows, Mac and 64-bit Linux.
The recommended way to install pyqt on Raspberry Pi is with apt.
Feb 2020 Update: sdist now available

5 years ago I’ve built it from source on the Pi.
Here is the riverbank software source download page: https://www.riverbankcomputing.com/software/pyqt/download5

5 years ago Do you have instructions to build from source on a Pi?

5 years ago Sure! Here is how I built and installed PyQt5 5.10.1 for Python 3.5 on a 3B+ running Stretch.
sudo apt-get install qt-5default qtdeclarative5-dev qtlocation5-dev libqt5* qttools5-dev qtmultimedia5-dev qt5help qt5multimedia qttranslations5 qt5-make qtbase5-dev <- updated the list of packages I believe are required to configure and build almost all pyqt modules

5 years ago FYI, Phil is working towards a proper source package for PyPI..
https://www.riverbankcomputing.com/pipermail/pyqt/2018-August/040704.html
I am (slowly) moving towards being able to have source packages on PyPI - but that would require you to have Qt already installed.

4 years ago Update: PyQt5 sdist is available for the last two releases on PyPI.
We just need to know what the build dependencies are, and we'll try and build the wheels.
@altendky are there any docs on this?

4 years ago @bennuttall, I haven't gotten into that yet. I would expect it would want 'Qt'. I'm not sure what else. Is there somewhere I could go to see the build errors and to try to address them? If not I can just try to do it locally on my rpi and come back with a list of what I have to install.

4 years ago I'll be able to get the logs. What's the minimum python version supported in the latest version?

4 years ago Looks like 3.5-3.8. Are the builds not public? I don't know anything yet about how contributions are handled or CI etc.

4 years ago This is on my main PC (not rpi) which has presumably had some various stuff installed. Just doing this as a first pass. I'll try to follow up on my rpi, then maybe a fresh install on it as well. And woops, I ran install rather than building a wheel... but, presumably similar requirements to address. This is taking awhile and so I'll share it as is in case you are digging in parallel. I'm going to reinstall my rpi and follow up there.

Not currently. Builds are made on real Raspberry Pis in a Pi cloud service. The build logs get output into a database, and we can retrieve them from there when we need to.

2020-01-06T00:47:53 AttributeError: module 'sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel' Looks like the same error as I had above. The build is expecting qmake to have a default Qt chosen. Apparently apt installing qt5-default is one option. If you want another I can dig on it. After that it did build for me. Admittedly on my desktop with who knows what else it needed already installed, but that's what I've got for now. I grabbed the latest raspbian to try and wasn't getting any hdmi output and I haven't resolved that yet.
I did also work a bit on updating pyqt5-tools to the new PyQt5 5.14+ build system last night so I'm getting some exposure there. If you build with sip-build yourself rather than using pip you get some more control. Though we may well not need that.

4 years ago Great, thanks.
Can you do this process to see what dependencies it has? They're not strictly the same as build-deps but would at least shed some light.

4 years ago I haven't gotten back to fixing my rpi. I've been working through getting the build going for pyqt5-tools. Is there a new error to figure out?
altendky

4 years ago Here is a preliminary procedure that while presumably quite wrong can hopefully be a useful step forward by providing some answers to the questions above and something to correct. I did not get my own Pi running but instead rented one from Mythic Beasts. While that leaves us without Raspbian Lite for the moment (rather regular Raspbian Buster), it does get us exactly the same environment as the real builds will occur in as far as I know.

I X-forwarded and ran below and saw an empty widget shown. Not much of a test but... it ran.

application = PyQt5.QtWidgets.QApplication([])
widget = PyQt5.QtWidgets.QWidget()

widget.show()

application.exec()I don't know what the build preferences are for piwheels. Probably don't want manylinux2014 since python3-pip isn't new enough to handle it (even if I would personally almost always use a virtualenv or venv). I don't know if we generally build against new (maximum features) or old (maximum compatibility) system libraries. I haven't compared this wheel against the official PyQt5 wheels to make sure they contain the expected support.
Let me know what the next step is. Thanks.

Doesn't it have QML support ?
I have a PyQt5 5.15 wheel with qml and android support. it is 15mb. I had extracted it from "Pydroid" app from playstore (some russian dude built that wheel)
Here is the wheel :- (rename it from .zip to .whl) PyQt5-5.15.0-py3-none-any.zip
