A const is automatically static, so your compiler needs to see the extern
declaration of moovariable in moo.cc too.
Do it just this way:
moo.h:
extern const struct moostruct moovariable[];
moo.cc:
#include "moo.h"
const struct moostruct moovariable[] = { ... }
moo2.cc:
#include "moo.h"
// without this line: extern const struct moostruct moovariable[];
This should help.
