This is done by checking the specified executable's dynamic linking information, and invoking the loader to parse its output for a version string. If the loader is musl, the output would be something like:: musl libc (x86_64) Version 1.2.2 Dynamic Program Loader �rbNT)�stderr�universal_newlines) � contextlib� ExitStack� enter_context�open�OSErrorr: � subprocess�run�PIPErR rV )rS �stackr �ld�procs r �_get_musl_versionrc V s� � � � � � � (�5� ��#�#�D��T�$:�;�A� %�Q� '�� (� �� �>�>�2�$�z���4� P�D� �t�{�{� +�+�� � �� (� (� ��(� (�s- �B�B� B� B� B�B�B�B$�archc # � K � t t j � }|�yt |j dd� D ] }d|j � d|� d| � ��� � y�w)aT Generate musllinux tags compatible to the current platform. :param arch: Should be the part of platform tag after the ``linux_`` prefix, e.g. ``x86_64``. The ``linux_`` prefix is assumed as a prerequisite for the current platform to be musllinux-compatible. :returns: An iterator of compatible musllinux tags.
