I think that the problem it's that i use g++ ( because it's a CPP code )
i have a function name int PlayerMain(void) in my code but it do not seems to find it... how can i do ?

I use the CodeWave head file between a #include "C" form but it do not change a things.... please help..

If PlayerMain() has to be a C function, then you need to put extern "C" { } around its prototype.

To solve the interwork problems, compile your other modules with -mthumb-interwork.
