Building Moonray for Houdini 20 (GCC11.2)

[adro79]

Hi there!

I'm spending this vacations to try build Moonray for Houdini 20. There's an error I previously reported when trying to build for Arch Linux but it was suggested to use gcc9 instead.

I would need some hint for this since I'm not used to code.

Here's the error log:

There's two more errors similar to this one. I'll upload the full log in a txt since it's a little bit large -> moonray-gcc11-errorlog.txt

Thanks in advance!!

Was able to surpass this error with ABI_VERSION=0 as the Rocky Linux 9 Guide menitons.

[adro79]

Hi, I finally got Moonray running on Houdini 20 by building it on a Rocky Linux 9 Docker Container!

At this moment, it crashes quite a lot and shader nodes appear empty when created. I'll create a guide once I get a decent build.

If you need some houdini logs let me know.

Got this log in houdini, I don't know why this happens.

Traceback (most recent call last):

[rgwilson68]

No Python module is found for pxr.MoonrayShaderParser or pxr.MoonrayShaderDiscovery because these plugins don't have Python modules : not sure why USD/Hydra always reports this as an error, since in this case Python modules are not needed, but it does. The error shouldn't impact functionality, so it probably isn't the cause of the other problems you are seeing.

Thanks for the reply, I got the materials working by reverting the HDAs from the otls folder to the initial commit version. Seems like this commit broke the HDAs or aren't compatible with my environment.

I think everything's working now, feel free to close this out.

I'll write a detailed guide soon, just like Brian did.

Hi, sorry for the delay.

The guide is available now! You can check it here: https://github.com/adro79/openmoonray/discussions/2
