Hi,
I want to trace SPU activity using the Cell BE Performance Debugging Tool. I followed the instructions of the CBE_Programmers_Guide which goes well for C code.
But now I have my program written in C++ code. If I try to compile the SPU code I get the following error:

...
Is there any way to trace SPUs with C++ code? Would it help if I rewrite the SPU code to C code? But how would I then link the SPU C code with PPU C++ code?
Kind regards,
Dominik
