Is magic_enum supported on WindRiver VxWorks 7 SR 0640 LLVM/Clang 9.0.1

[fnj7]

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 #46

Thank you for taking the time to look. If I ever figure it out, I will let you know.
