following the help topic on AU Wrapper I have managed to compile libauwrapper.a and am trying to bundle a VST3 into an Audio Unit, as per the Again example (public.sdk/source/vst/auwrapper/again). I keep however getting FATAL EROR: OpenAComponent: result: -1,0xFFFFFFFF when running auval for validation.
I have noticed some curious behaviour. The build output folder ends up with both an again_au.bundle (?) and again_au.component. The bundle contains a plist and again_au inside Contents/MacOS and nothing else. The component contains a Contents/Resources folder containing again_au.rsrc and the VST3 plugin inside the plugin.vst3-folder.
The Info.plist file (using audiounitconfig.h to populate values) inside the source folder isn’t reflected in either .bundle or .component making me wonder whether something is missing in the example CMakeLists.txt file. I have manually added it inside the generated component which leads to auval validating the plist, but still failing to open the component. Any leads to what could be missing as Apple’s (spartan) documentation on auval and error codes shrouds things in further mystery… Is there an example again_au.component available somewhere to compare its contents ?
