Apple Silicon : mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')

[mozzipa]

Because instruction for Apple silicon in Readme.md has been applied, CMAKE_SYSTEM_PROCESSOR from cmake . appears arm64.
But, there is warning as below for cmake .

-- Accelerate framework found
-- CMAKE_SYSTEM_PROCESSOR: arm64
-- ARM detected
-- CMAKE_SYSTEM_PROCESSOR: arm64
CMake Warning at ggml/src/CMakeLists.txt:48 (message):
  Your arch is announced as x86_64, but it seems to actually be ARM64.  Not
  fixing that can lead to bad performance.  For more info see:
  https://github.com/ggerganov/whisper.cpp/issues/66#issuecomment-#1282546789


-- ARM detected
-- Accelerate framework found
-- Configuring done (0.1s)
-- Generating done (0.0s)
-- Build files have been written to: /my/path/rwkv.cpp

Furthermore, below error occurs for python rwkv/generate_completions.py /my/path/rwkv.cpp/models/rwkv-4-raven/ggml-model-q5_1.bin

OSError: dlopen(/my/path/rwkv.cpp/librwkv.dylib, 0x0006): tried: '/my/path/rwkv.cpp/librwkv.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')), '/System/Volumes/Preboot/Cryptexes/OS/my/path/rwkv.cpp/librwkv.dylib' (no such file), '/my/path/rwkv.cpp/librwkv.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64'))

For your reference, similar error for llama-cpp-python was solved with arch -arm64 pip install llama-cpp-python --no-cache-dir
It might be similar solution mentioned in above github link from warning.

Additionally, arch -arm64 cmake . and arch -arm64 cmake --build . --config Release were not valid.

I get similar problem even without that warning.

I have Mac with non-intel CPU. Somehow the build-scripts detects ARM64 but when running assumes x86.

[joakimeriksson]

My problem was that my conda environment used an x86 python while the compiler did compile for arm64. Replacing the conda environment with an arm64 worked.
