Here is the error when I run python setup.py install
I am using gcc 8.2

I've got a similar error, also on CentOS.
It seems that some gcc distribution (incorrectly) put max_align_t in a wrong namespace. Should be fixable by adding a macro for CentOS that removes the std:: namespace for max_align_t. Contributions are welcome.
Having the same problem on . any fix? tnx

Just to clarify, rewriting std::max_align_t to max_align_t in scene.cpp fixes this error for me.
