[GRASS-dev] version difference between addon and GRASS core: automatic or only when relevant libraries change ?

[Moritz Lennert]

A colleague is using a dev version of GRASS 7.2 installed on windows.
Trying to use a C-addon (r.object.geometry), he got an error about
version mismatch between the installed GRASS revision and the revision
of the GRASS base the addon was built against.

Does this message automatically appear when the revisions are
different, or only if relevant libraries have changed between the
revisions ? I imagine that the latter would not be easy, but does the
former really have to lead to a fatal error ?
