Build error

[lindemeier]

I get the following build error:

OS Ubuntu 20.04

USD version v22.05a compiled with:

python build_scripts/build_usd.py --usdview --openvdb --materialx /usr/local/USD

RPR compiled with:

 cmake -Dpxr_DIR=/usr/local/USD -DCMAKE_INSTALL_PREFIX=/usr/local/USD .. &&\
    echo "building RadeonProRenderUSD" &&\
    cmake --build . --config Release --target install

Could this be an issue of the USD or OS version?

[lindemeier]

I see there is PR #557 that might be related here.

I'll try other versions of USD to check which is the most current supported version. I can then create a PR for the README that lists the max supported USD version.

[lindemeier]

Most recent working USD version for me is v21.08
