[bug#44045] [PATCH 00/10] WIP Ultimaker Cura

[Malte Frank Gerdes]

Hi,

this series adds Ultimakers Cura software to Guix. It's WIP because the cura
program itself segfaults while starting and i am not getting further as to why
this happens. It would be great if someone interested could take a look :-)

The trimesh python library cannot be built, because pyinstrument-cext can't be
built. This is due to the fact that the used URLs to fetch the source archive
don't exist. I have yet to find out how they are generated.

The python packages should be at the correct place, but i'm not usre where the
cura packages should be placed. Is engineering.scm the right place? If so i will
sort them alphabetically.

for pyinstrument-cext, try replacing the string in pypi-uri to
"pyinstrument_cext", with an underscore.

Thanks for the s/-/_/ tip! This works :-)

Having that out of the way i noticed that trimesh's testsuite dependes
(for whatever reason) on a javascript library which has to be generated
via npm, which is currently not available in Guix. Therefore i disabled
the testsuite from trimesh.

Attached is a corresponding patch.

Thank you very much 🙂. I already forgot about it. It's extremely nice to
finally have a decent slicing Software in Guix!

Hello Malte,

could you explain how to set up cura properly? When using the package
some things seem to be missing like generic materials, default profiles
and so on. Thanks!
