Crash on startup (clean installation)

[alex-w]

Expected Behaviour

Create a default environment on startup of Stellarium and run planetarium

Actual Behaviour

Crash on startup after getting location from IP address

Steps to reproduce

1. Make a clean installation of Stellarium (or rename existing directory with settings)
2. Run Stellarium

System

• Stellarium version: master (23.3.346)
• Operating system: macOS 11.7.10 / Ubuntu Linux 22.04.3

I don't reproduce the crash on Ubuntu 20.04 after renaming ~/.stellarium.

[alex-w]

Probably the crash reproducible for Qt6-based packages only (I got crash on both machines with Qt6)

[10110111]

I'm using Qt6 here.

under gdb:

Got location "Barnaul, Altai Krai, Russia (53.3597, 83.758; Asia/Barnaul)" for IP "176.212.122.222"
Unable to find module called "LandscapeMgr"

[alex-w]

See StelLocationMgr.cpp:1176 - why LandscapeMgr called before loading?

[alex-w]

Possible solution (see StelLocationMgr::changeLocationFromNetworkLookup()):

LandscapeMgr *lMgr=GETSTELMODULE(LandscapeMgr);
QString landscapeAutoName;
if (lMgr && lMgr->getFlagLandscapeAutoSelection())
{
    QColor color=getColorForCoordinates(loc.getLongitude(), loc.getLatitude());
    landscapeAutoName=QString("ZeroColor(%1)").arg(Vec3f(color).toStr());
}

But this solution will break logic for coloring the "fake landscape"

See StelLocationMgr.cpp:1176 - why LandscapeMgr called before loading?

Try backtrace command to see where this call comes from.

Yes, I have run into the same problem today testing build on a super-old Core2Duo. Struggled with that with broken GPU, and now suffering from lost Geforce drivers on fresh Ubuntu 22 update. Nouveau has broken graphics on a 9600GT. Sorry, it has to do with my latest fixes around auto-landscape from GPS/network.

Hello @alex-w!

OK, developers can reproduce the issue. Thanks for the report!

[gzotti]

@alex-w Something has broken a few weeks ago with the macOS CI build (errors during tool installation and "brew"ing some dependencies). And there is a deprecation warning for the Linux build as well. Can you look into these things please?

Damn... The results is weird - the unit tests looks like he depends from flags of compilers

And there is a deprecation warning for the Linux build as well. Can you look into these things please?

Where is a deprecation warnings?

[gzotti]

[alex-w]

Done.

So, linux (qt5/qt6) and macOS (qt5/qt6) in the box now
