ARM64 Compilation Error

Mammogram6672 · December 28, 2023, 11:18pm

I’m trying to make an Anki build for Orange Pi 5 with Ubuntu 22.04…
However, it displays this error.

Build failed.

Installing via pip is chaotic and crashes all the time.

I’m using N2, I installed all possible dependencies.

# Anki development

## Packaged betas

For non-developers who want to try beta versions, the easiest way is to use a
packaged version - please see:

https://betas.ankiweb.net/

## Pre-built Python wheels

Pre-built Python packages are available on PyPI. They are useful if you wish to:

- Run Anki from a local Python installation without building it yourself
- Get code completion when developing add-ons
- Make command line scripts that modify .anki2 files via Anki's Python libraries

You will need the 64 bit version of Python 3.9 or later installed. 3.9 is
recommended, as Anki has only received minimal testing on 3.10+ so far, and some
dependencies have not been fully updated yet. You can install Python from python.org

# Linux-specific notes

## Requirements

These instructions are written for Debian/Ubuntu; adjust for your distribution.
Some extra notes have been provided by a forum member, though some of the things
mentioned there no longer apply:
https://forums.ankiweb.net/t/guide-how-to-build-and-run-anki-from-source-with-xubuntu-20-04/12865

You can see a full list of buildtime and runtime requirements by looking at the
[Dockerfiles](../.buildkite/linux/docker/Dockerfile.amd64) used to build the
official releases.

Glibc is required - if you are on a distro like Alpine that uses musl, things
may not work.

Users on ARM64, see the notes at the bottom of this file before proceeding.

**Ensure some basic tools are installed**:

I’m not sure about that error, but with the following doc tweaks, ./run works successfully for me on Ubuntu 22.04 ARM. When making changes, remove out/ before building again.

What do you mean “chaotic”? Crashes are probably caused by Qt, and if that’s the case a source build will likely fare no better.

Mammogram6672 · December 30, 2023, 12:05pm

It crashes all the time until it stops working.

Thank you! Now it seems to be something much more stable.

Unfortunately, compilation on Ubuntu 22.04 still shows the same error as the first post.

So, I decided to compile it on Ubuntu 23.10 with qt6 and it is working perfectly.
It is possible to compile with qt6 using Debian 12+ or Ubuntu 23.10/24.04+

I would like to ask a question, if possible.
Using this command will I have even more stability?

RELEASE=2 ./tools/runopt

dae · January 1, 2024, 2:21am

The window that shows the first time Ubuntu 22.04 desktop is started did the same thing for me. Ubuntu Desktop on ARM is probably not ready for prime time yet, which is probably why they don’t provide a desktop iso

It has no effect on stability, it will just make things run faster.

langfield · January 2, 2024, 2:53am

@dae Does the default build process create a statically linked binary, or do you need to fiddle with QT installation on any machine you want to run your Anki executable on?

Also, when you built successfully for 22.04, were you using QT5 or QT6?

Mammogram6672 · January 2, 2024, 12:04pm

Packaged builds are not supported on ARM Linux. Qt is dynamically linked.

You can run the command shown on the last line manually to see if it prints anything useful. If not, and removing out/ and rebuilding doesn’t help, maybe the pip-sync authors will have some advice.

Mammogram6672 · January 11, 2024, 8:13pm

@dae

I’m going to brake again even with the QT6…

Is there any way to check the logs and find what’s missing?

Sorry, I don’t know what the problem is, but it’s likely an issue with QtWebEngine in that configuration. The statistics screen works correctly for me on a Debian ARM system.

I finally got this to work on Debian. Here’s some Debian-specific tips:

My approach was build from source using ./run, I was not trying to build a binary bundle.
I followed these instructions: anki/docs/linux.md at 8f77e5198b2e0a3019fa143e621a80ae62961f20 · ankitects/anki · GitHub
It was critical to export those environment variables.
Do not use conda. This was hell. I recommend deactivating your environment or removing it entirely before attempting this.
Make sure you know that the venv and python binary that the build process is using is in out/pyenv/bin, it is not the system python. However, because of the exports above, it can see the system python packages. Use these binaries to check that the imports work before re-attempting the build.
I ran into a bunch of PtQt6 import errors. Probably you want to install things with pip unless they start trying to build qt6 stuff from source with qmake. Don’t actually let pip do this, it’s also hell. If you see it trying, search for the appropriate package name in the Debian sources and install that with apt instead. E.g. python3-pyqt6.qtwebengine.

      sipbuild.pyproject.PyProjectOptionException
      [end of output]

The above error is pip complaining, "I can’t see qmake on the PATH. As mentioned above, you could install qmake6 and then symlink it, but don’t. Trying to build things from source via pip is very annoying and the Debian packagers have already done all that work for you.

sudo apt-get install python3-pyqt6.qtwebengine python3-pyqt6.qtwebchannel python3-pyqt6.qtquick pyqt6-dev-tools

Pretty sure I installed PyQt6-sip (PyQt6-sip · PyPI) via the pip binary in the venv.

@langfield
You forgot 1 package.
That’s why it’s showing an error.

Try this:

sudo apt install python3-pip python3-venv pyqt6-dev-tools python3-pyqt6*

Before running the installation you can check these parameters:

echo $PYTHONPATH
echo $PYTHON_BINARY
