    Hi all,

    I am trying to install SofaPython3 on my ubuntu 18.04. During compilation, I received error message being “PythonTest.h:27:10: fatal error: filesystem: No such file or directory #include <filesystem>”. Then the compilation terminated. I also tried to modify it as #include<experimental/filesystem> but received a huge error towards the end of compilation. Has anyone else encountered similar issue and is there a way out of it?

    Cheers

    I was doing exactly that yesterday and I think the problem may be gcc-8 (supposing you’re in Ubuntu 18.04 using the default packages) or pybind11 > 2.8 (something changed that broke SofaPython3). I would advise maybe try using gcc-9 and compiling pybind11 2.6.2.

    Hi Alexandre,

    Thanks for your reply. I just downgraded pybind11 from 2.8.0 to 2.6.2 and selected gcc-9 and g++-9 for compiling. Now the filesystem error is gone and I’ve successfully compiled it.

    Cheers
