Error while running setup_env.py -md models/BitNet-b1.58-2B-4T -q i2_s

Hi developers,

When I followed the tutorial (Build from source), and run python setup_env.py -md models/BitNet-b1.58-2B-4T -q i2_s, the printed error is:

INFO:root:Compiling the code using CMake.
ERROR:root:Error occurred while running command: Command '['cmake', '--build', 'build', '--config', 'Release']' returned non-zero exit status 2., check details in logs/compile.log

Then I went into logs/compile.log, the error should be:

[  2%] Linking CXX shared library libggml.dylib
[ 11%] Built target ggml
[ 12%] Linking CXX shared library libllama.dylib

Would you please help me check the problem? The error Undefined symbols for architecture arm64: "std::__1::__hash_memory(void const*, unsigned long)" seems very strange and have no idea how to deal with.

The enviroment I used:

• MacOS 26.0.1

• Cmake version 4.1.2

• Clang version 21.1.4 (Homebrew)

• Python 3.9

Start with setup_env.py and reproduce the Build from source command on the reported arm64 system. Inspect logs/compile.log and the CMake build output to identify why linking libllama.dylib fails; done means the setup command completes successfully without the undefined-symbol error.
