Is magic_enum supported on WindRiver VxWorks 7 SR 0640 LLVM/Clang 9.0.1
I have a multi-platform project that uses magic_enum.
Have successfully compiled and ran in the following configurations:
- Windows 10 VS2019 CL compiler
- Windows 10 VS2019 LLVM/Clang 9.0.1 compiler
- Redhat 8 GNU 10 compiler
Attempting to compile example.cpp using WR Workbench 4.0, VxWorks 7 SR 0640, LLVM/Clang 9.0.1 and am experiencing several compilation issues similar to the following (full compile output can be provided if needed):

Is there any information that can be shared to help me move forward.
Am I trying to do something that is not supported?
Has anyone tried Magic Enum on VxWorks 7 SR0640?
Hi, I can’t understand what the problem is, and unfortunately I’m not familiar with VxWorks. I found only this issues https://github.com/Neargye/magic_enum/issues/46

Thank you for taking the time to look. If I ever figure it out, I will let you know.
FYI
I moved to VxWorks 7 24.03 and magic-enum compiled with one issue in magic_enum::enum_index()
