Cannot Build hermes-python with hermes master-3.1 branch under Linux

[JohnBussoletti]

Under Linux (Ubuntu 20.04) the hermes-python repository's Makefile claims that it cannont find a number of include files (e.g. compat.h and many others) even though they are in the hermes repository build tree. I noticed that they are in various directories under the hermes repository. For example, compat.h is in my /ots/sw/hermes/hermes_common/include/uti directory, but it appears that the Makefile for hermes-python expects it to be in the /ots/sw/hermes/hermes_common/include directory.

What branch/release of hermes is expected to allow a successful build of hermes-python?

Okay, I found some Doxygen files that show use of the Master-2.0 branch of Hermes2D seems to have the missing include files. So I switched to the Master-2.0 branch and lo and behold the missing include files show up. Unfortunately, it appears the current g++ compiler has become a bit to strict to compile the Master-2.0 branch without an error. I'm seeing messages:error: cannot bind rvalue reference of type ‘double&&’ to lvalue of type ‘XMLMesh::var::value_type’ {aka ‘double’}

and looking out on StackFlow, it looks like I may need to insert a "std:move(var)' structure in the code to get the compiler to correctly compile hermes.

I will keep fiddling, but it looks like hermes-python is not really supported anymore and hermes2d's older branches may not be compatible with current compilers.
