@MarsSeed I removed that pinned comment.

The DBUILD_OPENBLAS=OFF option means we need to install the OS version which is why it's in the requirements.

This package has been very difficult to update since LulzBot moved things around and I myself have moved on to use Cura with my LulzBot printers so I haven't spent any time lately to update these builds. I would be happy to turn this over to someone else if they are interested in updating it.

And @HarlemSquirrel, could you please kindly remove your comments that belonged to the old cura2-lulzbot but got migrated here?

It is very confusing to read that this is deprecated or it should be uninstalled when in fact this is the new package that is maintained and recommended to users.

Please remove dependency openblas, as it is turned off by your CMake config -DBUILD_OPENBLAS=OFF.

Or better yet, enable OpenBLAS, and depend on the new blas-openblas package that now provide the full suite of optimized blas/lapack.

Also please enable other options, especially the default ones. It does not make sense to define package dependencies but turning off their support in CMake build.

Good to know. Thanks!

Looks like the build scripts have moved to https://gitlab.com/lulzbot3d/cura-le/cura-le-build-environment

I've switched to using Cura myself with my Lulzbot printers so haven't built this in a few years now.

I get the following error trying to build with yay:

I get this after installing from a build in a clean chroot.

Original exception was:

It sounds like this is related to part of scipy being cythonized, its possible that it may need a downgrade or that we can tell cxfreeze about it directly. Is this working for others?

I'm not too familiar with building in chroot, I pretty much only do it manually for cura-le but I'd got it scripted so I don't mess it up the few times I try...

@bnalohim I think this needs to be built in a clean chroot. See the comments at the bottom of the PKGBUILD.

Also, this looks like an issue with your DNS: "fatal: unable to access 'https://gitlab.com/lulzbot3d/cura-le/cura-binary-data.git/': Could not resolve host: gitlab.com"

Hi! I'm getting an error with an undeclared GetArenaForAllocation...

I'm on manjaro and failed both on graphical installer and in console with pamac and yay

pamac results of the process: https://pastebin.com/3UfpF1U7

Thanks davidalb97, I've updated the dependencies and verified I can build the package.
