This is a last part of the output I've got:

Here is the list of dynamic libs, opened by the SBCL process:

Also, I has this in my CFFI directories:

and .qlot/dists/shirakumo/software/cl-vorbis-b41b20d0f8b2bce65d61b65b0508f054ff2c57ae/static directory contains these dynamic libs:

Seems the libvorbis library is not loaded on my M1 architecture:

)

Slots with :INSTANCE allocation:

  TYPE                           = :SYSTEM

  HANDLE                         = NIL
  PATHNAME                       = NIL

because it is built only for X86-64:

file libvorbis-mac-amd64.dylib
libvorbis-mac-amd64.dylib: Mach-O 64-bit dynamically linked shared library x86_64

I found a workaround. In the directory of cl-vorbis I did:

make CC=clang CFLAGS='-O3 -fPIC -g'

and applied this patch:

Now Kandria does not complain on missing stb_vorbis_open_filename.

CL-VORBIS should be fixed to include build for x86-64 and arm64 on Darwin.

Since I cannot compile on M1 I cannot create such a fix. Please submit a PR to cl-vorbis.

Ok.
