Bulding MoonRay CentOS7 last steps

[xXTR0YXx]

Currently trying to get everything working according to the docs, but the last steps don't seem to work for me

cmake --preset container-release gives me this error: The source "/openmoonray/CMakeLists.txt" does not match the source "/building/CMakeLists.txt" used to generate cache. Re-run cmake with a different source directory.

cmake --build --preset container-release -- -j 64 works and finshes, but have to set the 64 to 32 otherwise my machine chokes

cmake --install /build --prefix /installs/openmoonray gives me this error: -- Install configuration: ""

I can already see the finish line, but the last steps are not working for me

It looks like the /build directory still contains information from the previous step. Try deleting all the files in /build before running cmake --preset container-release

[xXTR0YXx]

yes, now it works until the last point, so the cmake --install /build --prefix /installs/openmoonray doesn't built anything into the /installs/openmoonray folder

So, everything up and running here. Only thing that gives me errors is when trying to run in XPU mode.

Warning (lib.render): GPU: Unable to load PTX file: /installs/openmoonray/scripts/../shaders/GPUPrograms.ptx ...falling back to CPU vectorized mode

@xXTR0YXx I had the same problem, solved here: #65 (comment)

[xXTR0YXx]

Actually it seems to work, just the scene didn't support it. I had other scenes that worked great without complaining and with XPU

Any idea why I can't find and run the rdl2_json_exporter? There is no such file in the /bin directory

Hi @xXTR0YXx and @BrianHanke

Have you met following problem on your CentOS7 build?
pxr.MoonrayShaderParser and pxr.MoonrayShaderDiscovery python modules are missing on my CentOS7 build and Rocky Linux 9 build as well.

source /installs/openmonray/scripts/setup/sh
export PYTHONPATH=/usr/local/lib/python

hd_render -in /openmoonray/testdata/sphere.usd -out /tmp/sphere.exr

Warning: in Tf_PyLoadScriptModule at line 122 of /build/USD-prefix/src/USD/pxr/base/tf/pyUtils.cpp -- Import failed for module 'pxr.MoonrayShaderParser'!

The docs say those warnings are harmless:
