Problems installing QML on M1 machine

New to Julia

I’ve been trying to install QML on my M1 MacBook Pro. However, it always fails at the precompiling step. I get the following error:

I tried building jlqml myself, which seems to have gone fine. I added it to Overrides.toml as documented and I added jlqml_jll as a package afterwards. Still, when trying the command “using QML” I get the error mentioned above.

Any help would be greatly appreciated!

@barche I guess we need to build qt5declarative for this architecture:
https://github.com/JuliaPackaging/Yggdrasil/blob/aaec98291b41c2ed3a9a4bfdd8bfacbf62d8ee0a/J/jlqml/build_tarballs.jl#L56-L58
?

Yes, and probably the other Qt5 jlls as well, not sure why they were disabled.

4

Anything I can do myself to get it working in the short term?

5

I assume you’re the using M1 Julia build, i.e. for ARM, and that’s the problem, so to answer for the “short term”, I would try the x86-64 Julia build. Rosetta 2 is supposed to handle x86-64, including that regular fully supported Julia, or at least I would give it a try (curious if it works for you).

6

Damn, don’t know why I didn’t think of that. Thanks, that does indeed work! It is sadly a good bit slower for my purposes, however, so that’s a shame.

Now I don’t know how I can make VsCode start the x86 repl though… (apart from connecting to the one I installed as an external repl).

7

I think you can just set the Julia path in the vscode settings to the x86 one. Note that @giordano and I started the work to add the M1 platform to the JLL, should be done soon.

Yes, you’re right, I didn’t look closely enough. I only looked at the environment path, which doesn’t work. I now indeed set the executable path, which does work, thanks for that.

Also thanks for working this out on such short notice!

9

It should work on M1 now, I haven’t tested this because I don’t have an M1 machine. The speed is entirely thanks to @giordano 's superhuman efforts in keeping on top of Yggdrasil.

Had to do a clean install of Julia, but it seems to work now! Thanks guys!

Actually, it’s not working completely like it should. If I start my script with “Using QML” at the top (without any QML specific code), my REPL seems to crash, and throws

Moreover, VScode gives me the following message

If I start my code with using QML commented out it runs fine. Then once it has run, I can just add using QML again and it runs fine…

Julia 1.7 on the M1 suffers from segmentation faults like that:
https://github.com/JuliaLang/julia/issues/41440
This has been fixed in the upcoming v1.8.

Thanks,

I just tried the 1.8 beta, but I’m getting this error when using QML

Are you aware of this?

Likely a bug in the package.

This is a bug in CxxWrap that is fixed in main, can you try with add CxxWrap#main?

That works actually, thanks so much! I did try updating CxxWrap, and I assumed it would be pulled from the main branch, but I guess that’s not the case? I’m kind of new to Github etc. so sorry for my ignorance, but why does add CxxWrap#main install something else then just running add CxxWrap?

17

With CxxWrap#main you get the latest commit in the git repository, otherwise you get the latest version that was released.

I see, that makes sense. Thanks!
