as per title, when e.g. I try to auval it on a Yosemite machine, I get the following:
2019-10-29 17:37:49.062 auvaltool[25543:10647648] 17:37:49.062 ERROR: >compload> AudioComponentPluginLoader.cpp:513: ResolveFactoryFunction: CFBundle 0x7fd8a84187b0 </Library/Audio/Plug-Ins/Components/TestProject.component> (bundle, not loaded): cannot load bundle: The bundle "Test" couldn't be loaded. FATAL ERROR: OpenAComponent: result: -1,0xFFFFFFFF
the plug-in was built on macOS 10.14 using Xcode 11.1 (the latest at the moment of writing).
There are two more odd thing:
- the stand-alone app of the same project, also built with Xcode 11.1 runs without problems on Yosemite
- the same project, built with Xcode 10.3, on the same machine with the same macOS version, results in a plug-in that run without problems on Yosemite.
So, the problematic combinations seems to be plug-in output + Xcode 11.1.
All previously mentioned builds have been done with
- libc++ with C++11 support
- 10.7 as Deployment Target. Changing it to 10.9 or even 10.10 didn’t make any difference in the outcome
