Hi Laurens, hi all,
Hum, could you give me a hint, please? If I write:
class BBB : public osgDB::ReaderWriter {... blah blah blah ...};
REGISTER_OSGPLUGIN(bbb, BBB)
in "bbb.cpp" (in my main exe), then the "BBB" reader/writer is constructed and
added to the registry when process loads.
However if I put that .cpp in a static lib, which is linked to my main exe,
then the "BBB" reader/writer is never built (nor added to the registry).
As far as I know, static libs are roughly a bunch of objects! Were's the
difference?
And of course, using USE_OSGPLUGIN() doesn't work.
BTW, The feature you're mentioning seems interesting. Is there any chance you
release the code, under a licence or another?
Cheers,
Sukender
