do you get any relevant messages if you try it with the env var OSG_LOG_LEVEL
set to DEBUG (preferably with a debug build) ?

the define is in OSGConfigured.h, which is generated in your build dir (in one
of the subdirs belonging to libOSGBase) and installed together with the other
headers.

can you check what file suffixes are known to the system using:
std::list<const Char8*> sufList;
ImageFileHandler::the()->getSuffixList(sufList);
Cheers,
