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 �rbNr T)�stderr�text) �openr � interpreter�OSError� TypeError� ValueError� subprocess�run�PIPEr& r) )r' �f�ld�procr r r �_get_musl_version! s ,r6 z Sequence[str]z Iterator[str])�archsr c c sR t tj�}|du rdS | D ]2}t|jdd�D ] }d|j� d|� d|� �V q,qdS )a� Generate musllinux tags compatible to the current platform. :param archs: Sequence of compatible architectures.
