I have to use wide strings in my application for MorphOS (and another OSs). Unfortunately when I compile a source with wprintf function I get:

"undefined reference to `wprintf'"

I use wchar_t, std::wstring with no problems.
Can I use wprintf under MorphOS? How?

I use the last version of MorphOS SDK and GCC 4.4.5 under MorphOS 3.5 (PowerBookG4)
