ok, here the linker is told to link with OSGFileIO.

strange. Almost looks like the linker is doing the same thing the
windows linker does: if no symbol from a library is used the library
gets removed from the link - that can be the case here since OSGFileIO
essentially only registers a bunch of types with a factory in OSGSystem
so there is no direct use of symbols from OSGFileIO. Perhaps the windows
work-around is also effective:
Before calling osgInit add these lines:
OSG::preloadSharedObject("OSGFileIO");
OSG::preloadSharedObject("OSGImageFileIO");
(ImageFileIO essentially has the same issue).
[SNIP - ldd OSGFileIO]
ok, this looks like Collada support was compiled into the library. You
can also use:
std::list<const OSG::Char8*> suffixList;
OSG::SceneFileHandler::the()->getSuffixList(suffixList);
to get the list of file types that are recognized.
Cheers,
Carsten
