Add aarch64 binaries to releases?

[adamrankin]

Hello,

Is it possible to include a binary build for aarch64 into the releases?

[jcfr]

That should indeed be possible. We would be happy to review contributions.

Here are the steps:

• Create a static build of Qt and document how to create and update such a build. For each platform we currently support, we download a static build of Qt. See details at https://github.com/jcfr/qt-static-build
• Update continuous integration to build for aarch64. May be we can re-use some of the work done to support building cmake python wheel for aarch64 (see https://github.com/scikit-build/cmake-python-distributions/blob/master/.travis.yml)

The static build of Qt is 4.8.6. Did you want to continue using that version?

If you already have a Qt build for aarch64 and it 4.8.6, that is a good starting point.

What do you think of creating a release called applauncher-4.8.6-aarch64 in https://github.com/jcfr/qt-static-build/releases and update the README ?

If that sounds good, I will create the release and grant access so that we you can update the release description, upload file and describe how it was generated.

I'm still trying to wrap my head around all the automated build system stuff. Would this not be the same as the linux docker image, just with a different base image?

Edit: what I mean by automated build system understanding: can we add another entry to the circleCI system to also build aarch64, just have a different Qt-static docker image?

Ok, @jcfr I've made a docker image with Qt 5.12.10 built. Should I zip up the Qt build folder inside and upload it to a release?

Edit (links):
Docker makefile and dockerfile here:
https://github.com/adamrankin/qt-static-build

Docker image here:
https://hub.docker.com/layers/adamrankin/qt-static/5.12.10-ubuntu-20.04/images/sha256-adf327868df7a2e009d507376ce16333b3c8430a177b5b32b75efcf6c975ac94?context=explore

This is great.

I suggest the following next steps:

• check that you can run the test from the build tree of the AppLauncher
• check that the binary created can be run on the target platform (you can do make package to first create an archive)

Good call. libpng linking issues! Will update when I have a working package.

Should I redo my docker image to be based on a dockcross image? With my current docker image it would require an arm64 host to build the image

Edit: nevermind. I need to learn more.
