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�IOErrorr: � subprocess�run�PIPErU rY )rV �stackr �ld�procs r �_get_musl_versionrf V s � � � � � � (�5� ��#�#�D��T�$:�$:�;�;�A�A��� � � �� (� (� (� (� (� (� (� (� ���� $�Q� '� '�� (� (� (� (� (� (� (� (� (� (� (���� (� (� (� (� � ��t� �>�2�$�z��4� P� P� P�D� �t�{� +� +�+s1 �A1�#:�A1� A�A1�A�A1�1A5�8A5�archc # � K � t t j � � }|�dS t |j dd� � D ]}d|j � d|� d| � �V � �dS )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``.
