Building Cura (dev version) with MinGW-w64 works, but Cura fails on launch.

[umagi 8]

Hi nallath,

What I did was to open a normal Windows Command prompt window, and first set the following path:

 

set PYTHONPATH=G:\dev\cura-build\build\inst\lib\python3.4\site-packages

 

Then, I started:

 

python G:\dev\cura-build\build\inst\bin\cura_app.py

 

This starts Cura (developer version), with splash screen and all, including the crash after selecting the Printer. At the same time the following output was printed in the command window:

The error should now be more debuggable, since we have a clear culprit here:

I'm just not sure yet as how to procede with this debugging now, since I know nothing about qml nor Qt.

Try selecting the "Ultimaker Original" (without the "+") - if it now starts, it's probably related to this issue (there's a workaround but no solution yet...).

I didn't have this much issues in getting it to work on Linux. Windows is always a fickle beast in getting software like this to work.

But yeah, the issue tinkergnome posted should 'fix' the problem. What i can see from the rest of the logs is that most of the stuff you need did load correctly, so i'm moderately positive that you're almost there

Hi nallath,

 

But yeah, the issue tinkergnome posted should 'fix' the problem.

 

I found posts about the issue before and tried the --disable-textures. But that doesn't work in the development version of Cura. Since I don't know how to pass that launch argument, I followed the same procedure as described in another post, i.e. modified the Windows shortcut to the Cura executable and added the  --disable-textures switch there.

Also note that I successfully built Cura using the Daid script, and that I don't have the crashes with that version. All the posts relating to this crash seem to be from people not using the development version of Cura, which I am referring to here.

Well, I don't know. I spent my time setting up a development environment for PyQt (using Eclipse and its PyDev addin) in the hope of debugging the QML problem that apparently causes the crashes. Although I succeeded in running a simple example PyQt program, I still haven't figured out how to debug the Cura GUI in there... Maybe someone has a PyDev Eclipse project to do that already?

Hello umagi:

cmake generate arcus.sln after (includes ALL_BUILD.vcxproj, Arcus.vcxproj, example.vcxproj, INSTALL, PACKAGE.vcxproj, python_module_Arcus.vcxproj, ZERO_CHECK.vcxproj).

Just build Arcus.vcxproj?

I tried several other will have a bunch of errors......

by Cura beginners..

Thank you!!!
