OpenBlok does not compile in RPiOS lite Bookworm 64-bit

[ParadoxGBB]

I think it may be due to v12 of the compiler. Thanks so much if anyone can help get this working!

It's not clear from the pasted error message, but gcc suggests the actual fix:

Adding a

#include <iterator>

in src/system/InputConfigFile.cpp should fix the build.

Fixed, thanks!
