I've made this mistake a few times as well, it appears that you're using
the C++ compiler but using Performer's C bindings in your code. Since
we have both C and C++ bindings in the same DSO there's some #define's
you need to set if you want to switch to the "other" [as compared to
your compiler].

/*
 * When compiling with C++, the following options are available:
 *
 * Default -> use C++ API/types
 * #define PF_C_API 1 -> augment C++ API with C API
 * #define PF_CPLUSPLUS_API 0 -> do not use C++ API/types
 */

So perhaps it's simplest to just add -DPF_CPLUSPLUS_API=0 to your
compile line.

Enjoy,
Allan
