Hi @dakcarto

So I updated with your new dependencies provided today. I get a crash on startup.

I'll add some more diagnostics later today

For reference:

https://bugreports.qt.io/browse/QTBUG-57706 https://bugreports.qt.io/browse/QTBUG-58344

Not sure if I interpret these resources correctly. But it looks to be a bug in Qt 5.8 and fixed in 5.8.1.

timlinux commented 7 years ago

I'm still building here under 5.7 and the problem is magically fixed so I am not sure what the cause was...

m-kuhn commented 7 years ago

Was that ever a problem under 5.7?

dakcarto commented 7 years ago

Startup exceptions fixed in https://github.com/qgis/QGIS/commit/d303ca8

The Qt 5.8.0 regression remains. From QTBUG-58344, I surmised that the exception was caused by a missing QIcon file reference when QgisApp's QMainWindow GUI was loading. I found two such old PNG references in qgisapp.ui. Until the regression is fixed in Qt 5.8.x, the exceptions may still be thrown in similar circumstances from other parts of the app or with third-party plugins.

I closed this since more recent packages address the issue.
