ROSCO not building with clang/flang

Desired use case

Would like to build ROSCO in the same environment as other software in the exawind stack. This is an issue on AMD gpu based machines that rely on Clang/ROCm.

Description

Flang 18.0.0 gives the following error:

     30    F90-S-0091-Constant expression of wrong data type (/lustre/orion/cfd162/proj-shared/ndevelder/exawind-manager-11142024/environments/exawind-11122024/rosco/rosco/controller/src/ROSCO_Types.f90: 445)

Code versions

Main branch of ROSCO

Note

I know that this isn't necessarily something the ROSCO project can support, or something that other developers have time to work on, but even if there is slow progress, would love to have this documented and someday fixed. I'll keep hacking at it too and will post if I find anything.
