Sorry, I don't understand what you mean. Could you elaborate please?

Thinks this probably is the same error as i get:

What compiler are you using? It seems the compiler defines a macro named "linux". Do you find any documentation for that macro?

andreasbuhr commented 11 months ago

I do not find any compiler which defines "linux". It seems rather strange to me to do this, for a compiler.

This happens if you are missing the C++ version. The linux macro is deprecated but included if you don't specify a C++ version: https://godbolt.org/z/M3o1MMKv1
