The ESUG presentation this year was very comprehensive. I suggest making the slides and sample code more prominent/easily accessible from the code. Using the presentation, I tried to communicate with the portaudio lib (OSX 10.8.5, lib installed with brew). I did: PaInitialize <primitive: #primitiveNativeCall module: #NativeBoostPlugin> ^ self nbCall: #(int _Pa_Initialize()) module: 'libportaudio.dylib' The docs list the function name without the underscore, but nm revealed it with a leading underscore. For the module, I tried: - full path to dylib link above - fill path to actual versioned dylib file i.e. ...2.dylib - symlinking both into the VM Plugins folder I was thinking maybe this was the indirect function thing like chipmunk, but even "self nbGetExtenalAddress: 'Pa_Initialize' module: 'libportaudio.dylib' returned nil. I tried with and without the underscore, with the module specified all four ways. Thanks in advance for any guidance... ----- Cheers, Sean -- View this message in context: http://forum.world.st/NativeBoost-Documentation-Suggestion-and-Question-tp47...
