v0.31.1 (mlx-c 0.6.0's tested pairing) doesn't build on Xcode 27 beta's
Metal 4.1 compiler at all -- the steel/gemm kernels (BlockMMA, NAXSubTile)
fail with "must explicitly initialize the member" and address-space
qualifier errors. Bisected to ef5fc0fab27c63e6976e96b07c234c9e2601d8a7,
the minimum main-branch commit ("Fix implicit `thread` address space
qualifier becoming explicit in metal 4.1", 2026-08-04, mlx#3963) that
builds clean -- 168 commits ahead of v0.32.0, which does not include the
fix. No tagged release contains it yet.
Bumping the pin means mlx's fft:: functions now take an FFTNorm
parameter fft.cpp's auto-generated wrappers don't know about -- hand-
patched all 12 to pass FFTNorm::Backward, preserving pre-bump behavior.
Not upstreamable as-is (proper fix is regenerating this file against the
new API), but correct for this internal build.
See ~/.spel/models/mlx-local-runner.spel for the full bisection evidence
and a separate, unrelated GPU-matmul precision caveat this pin does NOT
fix (mitigated at the call sites that need it, not here).

MLX C
MLX C is a C API for MLX.
MLX is an array framework for machine learning on Apple silicon. MLX C expands MLX to the C language, making research and experimentation easier on Apple silicon.
MLX C can be used standalone or as a bridge to bind other languages to MLX. For example, the MLX Swift package uses MLX C to provide a Swift API to MLX.
For more information see the docs.
Install
CMake is required to build MLX C. You can install it with Homebrew:
brew install cmake
To build, run the following commands:
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j
From the build/ directory, you can run an example
that uses MLX C with ./example.
