You'll notice in my code that I still use pure c style coding without the use of strings. Even with pure c code, it still fails if run through the c++ compiler because of the function name magnling. I've tried with c++ code styles and it works as long as the ANE functions are not mangled, which is done by using extern "C". Also the function FREGetObjectAsUInt32( FREObject object, uint32_t *value ); is commented out in the NativeExtensions.h file with a warning about causing issues on certain versions of Flash/AIR. It didn't really specify if it was previous or prior to the version it had listed but in the little use that I have made if it I haven't has an issue yet.
Hopefully I will get done with a 1-1 port of the BBMSP functions as an ANE and post it here this weekend. After that I will try to actually make an ANE where most of the background work is done and you just call a function and forget the rest.
