Unable to use faust2au with macOS x86_64 on version 2.60.3

[shakfu]

Having installed faust 2.60.4 via the provided binaries to $HOME/.opt/faust and having set FAUST_INSTALL to the same directory and PATH to $HOME/.opt/faust/bin, I tried to compile a macOS audiounit plugin via one of the simpler examples (examples/generators/osc.dsp):

faust2au osc.dsp

This generated an Xcode project but produced errors during compilation which had to be fixed with the following steps:

1. Add $(HOME)/.opt/faust/include to HEADER_SEARCH_PATH
2. Enable "C++11 [-std=c++11]" in C++ Language Dialect
3. Cast int -> unsigned int in all places giving the error "Non-constant-expression cannot be narrowed from type 'int' to 'AudioUnitParameterID' (aka 'unsigned int') in initializer list"

After the above fixes, the compilation proceeded successfully and generated FaustAU.component.

Unfortunately after placing this audiounit in ~/Library/Audio/Plugins/Components or /Library/Audio/Plugins/Components it was not recognized by any of my DAWs (Ableton Live 11.3.3 or Reaper 6.80).

I finally checked it with a plugin validaton tool, pluginval initially with strictness level 5 or finally with the lowest level 1, but it was not validated with the following error:

Started validating: $HOME/Library/Audio/Plug-Ins/Components/FaustAU.component

Num plugins found: 0
!!! Test 1 failed: No types found. This usually means the plugin binary is missing or damaged, an incompatible format or that it is an AU that isn't found by macOS so can't be created.
FAILED!!  1 test failed, out of a total of 1

Any help on how to resolve this would be much appreciated.

faust2au is no more maintained, better use faust2juce and compile an AU from there.

@sletz thanks, that's interesting. I remember it working previously. I'll try the faust2juce translator then.

@sletz

I suggest not to remove faust2au in case someone can resolve the remaining issues.
