Cura from source libArcus not found

Hello,

Has anyone run Cura from source on Ubuntu 17.10 (fresh install) I have hit a snag where cura_app.py can't find Arcus, I compiled libArcus following the instructions on the github

 

$ mkdir build && cd build$ cmake ..$ make# make install

 

Their is a Arcus.so file in /usr/local/lib/python3/dist-packages

 

Original exception was:Traceback (most recent call last):File "cura_app.py", line 54, in import Arcus #@UnusedImportModuleNotFoundError: No module named 'Arcus'

I run Cura from source on Linux and have to use this little shell script (I install Cura under /opt/cura).

#!/bin/sh
PATH=/opt/cura/bin:$PATH PYTHONPATH=/opt/cura/lib/python3/dist-package /opt/cura/bin/cura $*

This crap forum seems to have screwed the formatting of the code but I hope you get the idea.

Hmm maybe I have done it wrong as I did not install cura I cloned the repos following Nallath guide he posted in one of the github issues.

“Checkout Cura, Uranium, CuraEngine, LibArcus.

Build LibArcus

Build Cura engine

Ensure Uranium is in your pythonpath.

Run cura_app.py with python3

If complaining about dependencies, install those with pip.

That's pretty much how i recently installed my new laptop.”

maybe this method does not work on Ubuntu :/

There's a repo called cura-build-environment. I built and installed that and it provides all (or nearly all) of the dependencies required to build/run cura. It takes a while to build but I found this the most reliable way of building cura from source.

I kept getting stuck with the cura-build-environment I tried googling on how to resolve it but most of the stuff I found did not work.

Okay fixed that error by merging in https://github.com/Ultimaker/cura-build-environment/pull/20

But now I'm getting this and have not been able to sort it out I tried installing setuptools using pip3 and installing python3-setuptools from the repos but nothing :/
