scipy 未找到系统信息错误:未找到BLAS/LAPACK库

我在buildroot中添加scikit-learn包,但它在构建步骤中需要scipy依赖性,因此我在python-scipy.mk中添加host-python-scipy,如下所示:

HOST_PYTHON_SCIPY_DEPENDENCIES += \
        host-python-numpy \
        host-python-pythran \
        zlib \
        lapack \
        python-numpy \
        python-pybind

然后我rebuild scikit-learn,但它给出了另一个错误No BLAS/LAPACK libraries found

/xxx/buildroot/output/host/lib/python3.10/site-packages/setuptools/config/_apply_pyprojecttoml.py:196: UserWarning: `install_requires` overwritten in `pyproject.toml` (dependencies)

...

numpy.distutils.system_info.NotFoundError: No BLAS/LAPACK libraries found.
To build Scipy from sources, BLAS & LAPACK libraries need to be installed.

Buildroot有MKL库吗?我如何添加它?
我循着这个建议得到了回答,但我碰到了另一个问题:

Traceback (most recent call last):
  File "/home/xxx/buildroot/output/build/python-scikit-learn-1.1.2/setup.py", line 329, in <module>
    setup_package()
  File "/home/xxx/buildroot/output/build/python-scikit-learn-1.1.2/setup.py", line 325, in setup_package
    setup(**metadata)
  File "/home/xxx/buildroot/output/host/lib/python3.10/site-packages/numpy/distutils/core.py", line 135, in setup
    config = configuration()
...
FileNotFoundError: [Errno 2] No such file or directory: './test_program'
make:***[package/pkg-generic.mk:293: /home/xxx/buildroot/output/build/python-scikit-learn-1.1.2/.stamp_built] Error 1

pkg-generic是做什么用的?有没有办法在不避免测试执行的情况下解决这个问题?我能得到一些帮助吗?

请查看https://patchwork.ozlabs.org/project/buildroot/list/?series=314036上的补丁系列,它将scikit-learn添加到Buildroot(但尚未审查/合并)。
scikit-learn和scipy打包起来相当复杂,因此在执行此操作时遇到麻烦也就不足为奇了。
