We only require C++14 but the compilers we test with support some C++17 features, e.g., filesystem. You are right that this change was made between 3.9.2.0 and 3.9.3.0. We should have put in an ifdef for backward compatibility here. If you change that line to boost/filesystem, does it work? That appears to be the only occurrence of that include.

Thanks for quick help.
The compiler is GCC 7.5 and there is a warning, it worked somehow with GR
3.9.2. but now isn't.
