Compiling 2.1 - problem with 'STRING_NONE'

Hi, currently I'm trying to compile again 2.1, but there is one annoying error, that didn't occur before:

note.h:108: Error: ‘STRING_NONE’ was not declared in this scope
       int string                { STRING_NONE };
note.h:108: Error: cannot convert ‘<brace-enclosed initializer list>’ to ‘int’ in initialization
       int string                { STRING_NONE };
                                                       
Can someone help?

Hmm, static constants instead of enums and braced initializers are C++11 features.
Might it be possible that somehow you don't compile with C++11 enabled?

Really don't know what happened, as it hadn't been a problem before ...
And now again it compiles (at least the 2.1)

Probably it was a git mismatch ... - I now have to try to compile also my updated version (I applied changes from miwarre for the 2.1 branch ...)

Probably this is an issue in the branch "testAdd_LuteChanges", where I have applied all the changes from the first big PR of miwarre to enable bass strings for lute tablature ...
Unfortunately the files, that are mentioned in the error message, haven't been changed at all, so I have no idea ...

Here is the message of qt:
