No, const variables have internal linkage, so they will not be seen outside

You mean declaring it in the header as "extern const int i" is the same as
.h: const int i;
.cpp static int i;
No, I mean that if you want a global const variable with external linkage,
the correct C++ way of doing it is
.h extern const int i;
.cpp extern const int i =<value>;
This is misleading, a better fix is to let the cpp file to know about
the header. So #include "version.h" is probably missing in version.cpp.
