Build failed on Ubuntu : cannot import name 'sysconfig' from 'distutils' about materialx HOT 4 CLOSED

When multiple Python environments are available in the system path, we've often found it necessary to provide more information to the CMake configuration process. In our cloud-based Ubuntu tests, for example, we'll commonly add "-DMATERIALX_PYTHON_VERSION=2" or "-DMATERIALX_PYTHON_VERSION=3" to the CMake command line, just to make sure our intent is clear:

https://github.com/materialx/MaterialX/blob/master/.github/workflows/build.yml#L23

Perhaps that's worth a try in your build environment as well?

Hi,

Thank you for your answer. There is the same error message :

MaterialX/build $ cmake -DMATERIALX_BUILD_PYTHON=ON -DMATERIALX_BUILD_VIEWER=ON -DMATERIALX_PYTHON_VERSION=3 ..

Maybe this is specific to my Python installation and Ubuntu upgrade to 20.04...

Yes, that's starting to look more likely -- that there's an issue with the Python environment itself. Perhaps a reinstall will do the trick?

I'll close out this issue for now, @johhnry, and feel free to bring up any additional build questions on the MaterialX forum (https://groups.google.com/g/materialx).
