[Solved] Cura won't start

Message

hrnick · Post by **hrnick** » Fri Jun 12, 2020 12:43 pm

I've installed cura-4.6.1 but haven't managed to get it to start.

[ebuild   R    ] media-gfx/cura-4.6.1::gentoo  USE="usb -zeroconf" PYTHON_SINGLE_TARGET="python3_7 -python3_6 -python3_8" 0 KiB

Running cura gives me the following output:

It seems to be something with Qt but I can't really figure out that component it fails to load. What could be wrong?

Any help would be appreciated! Thanks!

I don't really know where to go from there though. :/

I tried the Ultimaker forums but they only questioned why I choose to install cura through portage rather than using their appImage since it's the only version that they control and support. I'd prefer not to end up with a system with 20+ applications that I have to manually keep track of and update.

Something has happened now, cura seems to get further in the process but still won't start.

What's the sdk it keeps referring to? There seems to be something going on there but I don't know what that could be. Any ideas?

eccerr0r · Post by **eccerr0r** » Fri Sep 25, 2020 10:23 pm

Anyone know if ultimake / cura changed any of their child dependencies, and if not are those version numbers available?

The portage ebuild for cura uses >= for dependencies which may be wrong...

digitall · Post by **digitall** » Sat Sep 26, 2020 9:14 am

I think this was broken by the addition of curaengine-4.7.0 and other dependencies, which are missing cura-4.7.0.

I added a cura-4.7.0 and fdm-materials-4.7.0 ebuild to my local portage overlay and this built fine and starts with no issues.

I will look at submitting these as a PR or bug patch to portage.... though upstream is already at 4.7.1 so will add that as well.

@eccerr0r: I think you might be right about >= ... though it does need to account for -r1 and similar patch bumps... but not end up picking up 4.7.0 for 4.6.1 etc.

digitall · Post by **digitall** » Sat Sep 26, 2020 12:47 pm

Sigh. Worked out how this got broken. The only version of dev-python/uranium which is required for cura left in tree is v4.7.0 ... unfortunately, the matching cura-4.7.0 is not present, so all versions build ... but crash at runtime *facepalm*

eccerr0r · Post by **eccerr0r** » Sat Sep 26, 2020 2:13 pm

fsck this... That's exactly what I concluded after wrestling with this last night, and stopped working on trying to get cura working... API is still changing rapidly.
Probably you should go ahead and file a bug on b.g.o about this?

I installed slic3r, at least the gui comes up, but no profile for my printer... guess i'll have to hack something one way or another.

digitall · Post by **digitall** » Sat Sep 26, 2020 2:34 pm

I have fixed cura-v4.6.1 with this and should have fixed the ebuild to not do this again... I will submit a v4.7.0 and v4.7.1 set of ebuilds based on that. SIGH. At least with Gentoo, you can diagnose and fix the issues... but I do wish maintainers would do a bit more manual checks before pulling old versions from the tree:
https://github.com/gentoo/gentoo/pull/17679

eccerr0r · Post by **eccerr0r** » Sat Sep 26, 2020 3:09 pm

Ideally the API settles down and newer versions even if they don't match will still work... alas this is still too new it seems even with version 4.x ... *facepalm* Alas, looks like now it has to version lock.

digitall · Post by **digitall** » Sat Sep 26, 2020 8:13 pm

*shrug* It looks like the various libraries are used pretty much exclusively for cura so the upstream has no incentive to have stable API... especially if they are still in major development flux.

In any case, the main issue is that the cura ebuild should reflect this and pin the dependencies to match to avoid breakage, so users can actually just get on with their day!

digitall · Post by **digitall** » Sat Sep 26, 2020 8:15 pm

Anyway, if you want to use cura-4.6.1 or 4.7.0, then the ebuild changes from my PR above in a local overlay would get you a working cura... or at least one that builds and starts up fine. I don't warrant it as fully tested and bug free!

hrnick · Post by **hrnick** » Tue Sep 29, 2020 12:09 pm

Thanks for looking into this one!

It might be that there are two unrelated problems we are discussing. I did an emerge -C cura, followed by a emerge --depclean, I followed the steps on github and resinstalled cura. I also removed all configuration files I could find in my user profile (~/.local/share/cura, ~/.cache/cura and ~/.config/cura).

First I got ModuleNotFoundErrors for zeroconf and trimesh (that I found in a portage overlay). I don't know if these errors were related to any of the other things but now I'm back to the result I had in my first post.

so did you try

$ sudo eselect python set python3.7

as suggested in the bug reports?

This is still a bug however, but is a workaround for now.

BTW, digitall, are you a dev or proxy maintainer or something? Wonder when your commits will make it to the tree...

Same thing with the cura-4.7.0 ebuild now found in GitHub.

Is there any way of debugging this? Running cura --debug does not seem to make a difference. It seems related to QT so is there anything that could be done there? Thanks!

hrnick · Post by **hrnick** » Wed Oct 28, 2020 12:54 pm

Could someone who can run cura maybe share their set of USE flags to see if there are any clues there? Thanks!

eccerr0r · Post by **eccerr0r** » Wed Oct 28, 2020 1:04 pm

It looks like digitall's patches made it, I'll need to try to build cura-4.7.0-r1 with its new correct deps and see if it works any better...

Incidentally I finally built my first 3D model for a part I need, so would be nice to get it working (though slic3r seems to work.)

---

cura-4.7.0-r1 runs finally! GUI comes up just fine! I get a few errors about zeroconf, probably because I don't have USE=zeroconf ...
Looking at the GUIs between cura and slic3r, I think I like the slic3r UI better, cura looks too smartphone-like...

hrnick · Post by **hrnick** » Wed Oct 28, 2020 4:59 pm

Again it seems as if we are discussing two different problems here, I tried building cura with those patches and still get the same error.

To my experience I get a lot better print results using cura than slic3r out of the box. Maybe it's about configuring everything correctly but just moving to cura solved a lot of the problems I had before.

eccerr0r · Post by **eccerr0r** » Wed Oct 28, 2020 5:30 pm

Did you try reinstalling 4.7.0-r1 from scratch? Make sure you unmask the right dependencies too...

These are the specific dependency versions I'm using:

media-gfx/cura-4.7.0-r1
dev-libs/libcharon-4.7.0
dev-libs/libsavitar-4.7.0
dev-python/uranium-4.7.0
media-gfx/curaengine-4.7.0
media-gfx/fdm-materials-4.7.0
dev-libs/libarcus-4.7.0
dev-libs/stb-20200205
dev-libs/clipper-6.4.2
dev-python/PyQt5-5.14.2-r1

BTW the patches are in portage already and you don't need to muck your own ebuilds anymore...

hrnick · Post by **hrnick** » Sat Oct 31, 2020 12:51 pm

Thanks for helping out eccerr0r!

I again ran an emerge -C cura and an emerge --depclean. The only thing different in your list of dependencies is the version of PyQt5, I had 5.15.1 installed rather than 5.14.2-r1. To me this has seemed more like a Qt problem to me so this would be interesting to dig deeper into. Unfortunately PyQt-5.14.2-r1 fails to emerge right now but I'll try to figure that out and get back.

Thanks again!

I managed to downgrade PyQt5 to 5.14.2-r1 by first downgrading PyQt5-sip and sip. Unfortunately cura still won't start. I also deleted ~/.local/share/cura/ ~/.config/cura/ and ~/.cache/cura/ before trying.

Code: Select all

I'm still qurious about the USE flags used for PyQt5 and cura. Could someone please share them?

Thanks!
