ci: refactor cpu wheel build workflow by Bing-su · Pull Request #2164 · abetlen/llama-cpp-python

Bing-su · 2026-03-26T13:09:06Z

Builds widely reusable wheels.

In fact, since llama-cpp-python uses ctypes, there is no need to specify a Python ABI. Therefore, tags like py3-none-manylinux_2_34_x86_64.whl can be used.

Please check the build success log at this link:

macos-15-intel failed to build, so it was excluded.

INFO:auditwheel.wheel_abi:setting libc to glibc llama_cpp_python-0.3.19-py3-none-linux_x86_64.whl is consistent with the following platform tag: "linux_x86_64". The wheel references external versioned symbols in these system-provided shared libraries: libgcc_s.so.1 with versions {'GCC_3.0', 'GCC_3.4'}, libm.so.6 with versions {'GLIBC_2.27', 'GLIBC_2.2.5'}, libstdc++.so.6 with versions {'GLIBCXX_3.4.17', 'CXXABI_1.3.8', 'CXXABI_1.3.5', 'GLIBCXX_3.4.19', 'CXXABI_1.3', 'GLIBCXX_3.4.18', 'GLIBCXX_3.4.25', 'CXXABI_1.3.11', 'GLIBCXX_3.4.22', 'GLIBCXX_3.4.9', 'GLIBCXX_3.4.14', 'GLIBCXX_3.4.21', 'GLIBCXX_3.4.15', 'CXXABI_1.3.2', 'CXXABI_1.3.9', 'GLIBCXX_3.4', 'GLIBCXX_3.4.20', 'GLIBCXX_3.4.11', 'CXXABI_1.3.3'}, libc.so.6 with versions {'GLIBC_2.17', 'GLIBC_2.16', 'GLIBC_2.14', 'GLIBC_2.3', 'GLIBC_2.6', 'GLIBC_2.4', 'GLIBC_2.7', 'GLIBC_2.2.5'}, libpthread.so.0 with versions {'GLIBC_2.3.4', 'GLIBC_2.2.5'}, libgomp.so.1 with versions {'GOMP_1.0', 'GOMP_4.0', 'OMP_1.0'}, libdl.so.2 with versions {'GLIBC_2.2.5'} This constrains the platform tag to "manylinux_2_31_x86_64". In order to achieve a more compatible tag, you would need to recompile a new wheel from source on a system with earlier versions of these libraries, such as a recent manylinux image. INFO:auditwheel.main_repair:Repairing llama_cpp_python-0.3.19-py3-none-linux_x86_64.whl usage: auditwheel [-h] [-V] [-v] command ... auditwheel: error: cannot repair "/tmp/cibuildwheel/built_wheel/llama_cpp_python-0.3.19-py3-none-linux_x86_64.whl" to "manylinux_2_28_x86_64" ABI because of the presence of too-recent versioned symbols. You'll need to compile the wheel on an older toolchain.
