maya-usd ufe issue

[christophezito]

Describe the issue
The compilation seems to be fine except maybe for this warning (See attached build_log.txt):

nm: /path/to/maya/2022.5-2448/platform-linux/maya/lib/libFoundation.so: no symbols

Maybe nm -D would be a better fit (not sure).

When using maya-usd within maya, we can load a stage (The KitchenSet for example) and it's visible in the viewport, but when selecting a Prim, maya crashes with the following log:

The crash seems to happen when calling mayaUsdLib.Util.prettifyName(schemaTypeName).
I think this might more looks like a build or environment issue as this seems to be a huge bug and it has not been reported yet.

We did not have any problem with maya-usd-0.23, it seems it appears starting with maya-usd-0.24 and the fact ufe
is now usdUfe.

Build log
build_log.txt

Specs:

• CentOS Linux release 7.6.1810 (Core)
• GCC-6.3.1 (devtoolset-6)
• Maya 2022.5
• Maya USD 0.25.0
• Pixar USD 21.11

Any advice would be welcome....
Thanks

Would you be able to test this with the MayaUsd 0.25 that we built and provided in the Releases section here on Github? This would help to narrow down if its a problem in our code or a problem with your local MayaUsd build.

Hello,

Yes of course, this version provided on Github works well, this is why I suppose it might be a build issue on our side.

I thought the nm warning might be the reason of the issue, as it is used to set the ABI version during the build, but I tried to force and set the ABI version, the result is still the same.

[seando-adsk]

Maya 2022 was a dual-python version. I see from your build logs you are building MayaUsd for python 2. The default python version that Maya will run with is 3. So when running Maya are you running it in Python 2 mode for your MayaUsd plugin?

The plugin we provide on Github is also dual-python so it works whether you run Maya in py2 or 3.
