So, would it be possible to auto-generate a C binary interface which
doesn't change when you change the C++ object? Could it be little
than a shim layer? And I'm sure it could be source code
compatible, so a
plugin could be compiled in without the shim layer.
I am not sure how "auto-", but yes perhaps.
If you select the classes of interest, then use the output of nm to
find all the relevant functions in that class, you should be able to
do something simple but effective which will insulate from binary
changes as the classes evolve.
But I still think the current
directory distinction is not helpful. It doesn't (for instance)
which bits of API would need such auto-generation. Tools (quite
call into the Oil layer, for instance to get resources. Part of the
issue here would be designating which bits of API are meant to remain
stable, so they could be "en-shimmed".
I didn't mean to suggest that the whole task would be easy, just that
the use of C++ itself should not be a barrier.
