Compiler complains about it:

src/frameName.h:94:5: warning: non-static data member initializers only available with -std=c++11 or -std=gnu++11 [enabled by default]

I suppose that's why you added -std=c++11.

Can we make this static or move out of the class? It can also be defined in the .cpp file.

Making it static makes sure - we don't want to initialize this field for every instance of FrameName.

I added -std=c++11 because initializing vector of pairs resulted in compilation error. I'll check if it will work for static

We can keep it array of pairs, but static :)

Or even array of structs is fine too.

Changed it to static and moved from header to source file. Also it seems that if it is static it can be initialized without [12] without any errors
