media-libs/openusd-23.11 fails due to boost issue with multiple pythons

[cwpenhale]

Hey friends,

I've been working on an ebuild for openmoonray, and have been building and rebuilding openusd as I've been cranking on getting that whole project working. Cleaning up portage on my system, I noticed that I upgraded to python3_13 from python3_12 for some packages, and that I now had multiple pythons on my system. When I went to re-emerge openusd again, it didn't build, as boost was finding python3_13. I added this to the cmake args on the ::cg ebuild and it went through as expected:

-DPython3_EXECUTABLE="${PYTHON}"

Hope this helps. Let me know if I can provide any additional information.

Thanks! Connor

Where is a bug?

[cwpenhale]

Maybe rebuild OCIO with the expected python as well? I see its asking about _ZTVN16OpenImageIO...

Yes, i try did it -> not working

I try to build without ocio too (as can you see in log - it contain several attempts)

[brothermechanic]

@cwpenhale do you have working usdview?

[cwpenhale]

I think I need to recompile with "tools." Let me give it a shot.

[cwpenhale]

Been going down a rabbit hole with this one. I've got usdview to compile with PySide6, but uic -g python spits out PySide2 python files for some reason. Almost ready to test :)

@brothermechanic opened a new issue to track the effort: https://github.com/brothermechanic/cg/issues/81 . Close this one and pick it up there?
