Building Cura from the source - Fedora

[hyna 0]

Hi,

has anyone an experience with building the latest Cura from the source on Fedora?

I followed the commands from Ubuntu build script and everything passed without any errors. But when i try to run Cura, it gives me the following error:

 

Traceback (most recent call last): File /"cura_app.py/", line 14, in    import cura.CuraApplication File "/home/hyna/3dtisk/cura_dev/Cura/cura/CuraApplication.py", line 4, in    from UM.Qt.QtApplication import QtApplicationImportError: No module named 'UM'

 

Any suggestions?

Thank you,

Hynek

Did you set the pythonpath module? It has to include the libArcus/python folder and the Uranium folder.

No I didn't. That solved my issue! Thank you! Now I'm able to start the Cura.  

But it seems that there are some more errors to resolve

 

ERROR - Unable to find backend executable: /home/hyna/3dtisk/cura_dev/bin/CuraEngine

Well, the error is rather clear; it's looking for home/hyna/3dtisk/cura_dev/bin/CuraEngine , which it cant find. Make sure that the cura engine is at that location.

CuraEngine is a separate project, which you have to build as well:

https://github.com/Ultimaker/CuraEngine

Thanks, it works now. I had some other issues but mainly due to my mistake. I forgot to switch to 15.10 branch

But one issue still persist. I'm not able to change the Cura language. After the application restart, everything is still in English.

The reason why I do this is to setup the test environment for my colleague which do the translation to Czech language.

Do you have any advice how to fix the language problem?

Thank you,

Hynek

Check if there is an error in the log regarding to this. If it can't find a certain language, it switches back to default (English). It should log this.

Nothing interesting from my point of view.

Well, that means it simply uses english as that's the language set in preferences. You could try manually changing the .cfg file created by Cura to see if that works.

Config file (.config/cura/cura.cfg) is ok:

language = fr

which corresponds with the setting in Cura.

After a while i was able to track the issue to i18n/gettext.find() function.

And the conclusion is that all .po language files needs to be converted to .mo files.

So it is not a Cura issue, it just needs to be done manually when building from source

Its much better now to see the translated strings where they belongs.

Thanks for your help.
