[Building Error] Failed to build USD - Arch Linux

[adro79]

I'm failing to build USD in my Arch Linux system. My configuration is Python 3.9.9 and PySide2 5.15.2

Here's the last few lines before the error:

Here's the full log

I had some issues like this in Windows as well, related to setting the env vars incorrectly. I don't know if it's the same problem since I'm new to Linux.

Thanks in advance.

As a local workaround while awaiting a fix, you can add a using statement to the header to hoist size_t into the global namespace. Another workaround is to #include <stdint.h> since USD uses cstdint which has the std namespacing of this type.

PS, duplicate of #1721

Closing this out, this should be addressed in the latest 22.05 release.
