MacOS: FreeCAD 0.17.12322 Qt5 not starting

[blacey]

But the latest version 12593 doesn't…
It's a Python library related error:
I can get it running on my MBA, so I'm gonna try to set again. Matplotlib and PySide packages are the ones provides by Kyngchaos for QGIS.

M-Rick,

I just downloaded 12595 and it worked flawlessly.

We run regression tests in a continuous integration environment across all supported platforms including macOS. You can see the latest macOS build here - https://travis-ci.org/FreeCAD/FreeCAD/jobs/302139750 that ran all the tests successfully.

Furthermore, all of the application dependencies are packaged in the FreeCAD bundle so the matplotlib and PySide packages you mentioned should not matter. FYI, we use matplotlib 2.0.2 on macOS and a development version of PySide2 that is required for Qt5.

It seems that there must be something specific to your environment that is affecting the application library loading/execution. I vaguely recall users having issues when they had MacPorts installed but I thought we resolved it and don't recall the specifics. The point being, we have seen environment issues in the past, so they can happen.

This seems very suspect:

During initialization the error Matplotlib qt-based backends require an external PyQt4, PyQt5,
or PySide package to be installed, but it was not found. occurred in /Users/aymeric/Library/Preferences/FreeCAD/Mod/Animation/InitGui.py

Try moving the Animation directory located in /Users/aymeric/Library/Preferences/FreeCAD/Mod/ somewhere outside ~/Library/Preferences/FreeCAD to see if it resolves the issue - you may have an old, non-compatible Animation module installed.

If removing the Animation module doesn't resolve the issue, then given you are seeing an issue with python, it is important to confirm that the application is using the python 2.7 interpreter and dependent site-packages/libraries that are bundled within FreeCAD.app and not the system python or a separately installed python or site-packages. You can use the following command, after you CD to the directory where you placed the FreeCAD.app, to confirm the loaded dependencies:

DYLD_PRINT_LIBRARIES=1 ./FreeCAD/Contents/MacOS/FreeCAD

Deleting (or temporary moving) everything in the config directory ~/Library/Preferences/FreeCAD is always worth a try.

Maybe something happened with your download for GitHub?

1. The best place to look for a root cause is the Travis job, however all tests passed successfully and Travis uploaded the full archive to GitHub without error - https://travis-ci.org/FreeCAD/FreeCAD/j ... 7786-L7798

Try re-downloading from GitHub to see if you have better results.

That is because that is a new build that worked. I restarted the build right after I saw chrisb's post.

There is an actual problem that has been going on for a long time. I don't fully understand it, but sometimes the bundler script fails to find libjpeg that is referenced by some library and exits which is what causes the incomplete bundle. I think the tests still pass because the libraries still have absolute path references. The times I have looked at the log when the problem has occurred, it looks like the ports cache download was terminated for some reason.

I'm not sure how far back the travis logs go, but if you can find a log of an earlier problem build mentioned in this thread, you could see what I'm talking about.

Ah, thanks Peter! That indeed explains it.

I sifted through several logs but didn't find a representative failure - perhaps the next time it happens, you or someone else can post here and I will take a look at it...

[chrisb]

Thanks for the rebuild and taking care of the problem. Usually I don't update each version but I will have a daily look in the near future and post here if I see a problem.

[M-Rick]

I got the reason why I had troubles launching nightlies of FreeCAD, as I reported previously.

On the Mac, when I was trying the latest working versions, FreeCAD was located in a folder containing accented letters in its name.

[Kunda1]

Sounds like issue #2973

Current version did it again:
