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

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.

    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,

    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!!!
