ggml emits its loadable backends (per-microarch CPU variants, metal, blas) with a .so suffix even on darwin, while the core libraries (ggml-base/ggml/llama/ llama-common/mtmd) use .dylib. Split the distribution by suffix: .so DL backends go in the package root for ggml's executable-directory scan, .dylib core libs go in lib/ for DYLD_LIBRARY_PATH. The previous .dylib name-pattern matched none of the variants. Verified on an M4: ggml loads the apple_m4 CPU variant (SME=1) and Metal, model loads and generates correct tokens.

# Distribute the shared ggml/llama libraries from the CPU_ALL_VARIANTS build. Unlike the
|
|
# old fully-static fallback build, these have @rpath install names, so the otool loop below
|
|
# (which only copies deps that exist on disk) will not pick them up. The split is by suffix:
|
|
# - ggml emits its loadable backends (per-microarch CPU variants, metal, blas) with a .so
|
|
# suffix EVEN ON DARWIN. These go in the package ROOT next to the binary, because darwin
|
|
# run.sh execs the binary directly (no bundled ld.so) so ggml's executable-directory
|
|
# scan looks there.
|
|
# - the core libraries (libggml-base/libggml/libllama/libllama-common/libmtmd) use the
|
|
# platform .dylib suffix and are NEEDED deps; they go in lib/, resolved at load time via
|
|
# the DYLD_LIBRARY_PATH=lib that run.sh exports. -a preserves the version symlinks.
