Raspberry Pi 4

You're using upstream master OSG

Yes, ok.
I tried all of the suggestions

OpenSceneGraph-3.6 branch or OpenMW/osg 3.4 branch (fork of 3.4.1) or the official 3.4.1 stable release

https://github.com/OpenMW/osg/tree/3.4
https://github.com/openscenegraph/OpenS ... raph-3.4.1
https://github.com/openscenegraph/OpenS ... eGraph-3.6

But I still get the same error.

Code: Select all

This is my test guys.

Advices

1 compile open scenograph because the default one on the repo havent opengl enabled
2 use the rpi4 flags because raspbian gcc has retrocompatilibily with rpi1..or use another gcc from other distro.
3 update mesa, but dont install it on your system... use a home prefix and just preload the libgl lib, because it creates some troubles installing it on the system... it will break your system and put you on software renderer.

The atomic thing tha you see on that error its related to retrocompatibility with armv6 rpi1, not openscenograph. Hope you achieve it to compioe! Set the rpi4 flags on cmake!

We have another user who was compiling on Pi4, and they got it working.

Perhaps this thread can help? viewtopic.php?f=8&t=6134

Thanks, I'll give it another try.
I'll update if I get any results.

The RPi4 compile flags did the trick. Now it compiled successfully. I won't have time to test if it runs today though. More updates will come if I make progress.
