1 year ago We always set it. This used to work until Frontier came back from maintenance. It's like the AMD Clang doesn't have <filesystem> anymore. The fgradient application is the only thing that needs it so I'm just shutting off the amr-wind tests on Frontier. I dealt with a similar issue here https://github.com/AMReX-Codes/amrex/pull/3523 .

std::filesystem is new in C++17, could there be a missing compiler-flag somewhere that sets the c++ standard?
