WiiStella port - linker error

[pedlem]

Ok. I have been working for a day on a port of the Stella emulator and, after some minor problems and small code modificatios on it's C++ source code, I've actually managed to compile everything. Now I am stuck with a linker error as seen bellow:

As you see there are lots of undefined references. After some googling I discovered that some of them, at least the '__sIPL' stuff, should on this latter june build of libogc be available, but it is not. Would someone help me? Since I don't know and have no clue on what these functions should do and there are no docs which I could find specifying it, I have no way to proceed with my project, nor even by implementing them myself.

Hope someone can shere some bright thoughts on this problem.
