This can be distinguish by first 32 bites and it is called magic number. Proper value of magic number is with suffix _MAGIC. Suffix _CIGAM means reversed bytes order. Both fields can occur in two types: 32 and 64 bytes. FAT field inform that this library contains few version of library (typically for different types version). It contains information where Mach-O headers starts. Each section started with Mach-O header contains one library (So if file starts with this field it contains only one version). After filed Mach-O there are section fields. Each of them starts with two fields: cmd - magic number for this command cmdsize - total size occupied by this section information. In this case only sections LC_VERSION_MIN_MACOSX (for macosx 10.13 and earlier) and LC_BUILD_VERSION (for macosx 10.14 and newer) are interesting, because them contains information about minimal system version. Important remarks: - For fat files this implementation looks for maximum number version. It not check if it is 32 or 64 and do not compare it with currently builded package. So it is possible to false report higher version that needed. - All structures signatures are taken form macosx header files. - I think that binary format will be more stable than `otool` output. and if apple introduce some changes both implementation will need to be updated. i����NI���� I��� I���� I��� I�� I��� I�� I��� i$ i2 t magict cputypet cpusubtypet filetypet ncmdst sizeofcmdst flagst reservedt nfat_archt offsett sizet alignt cmdt cmdsizet segnamei t vmaddrt vmsizet fileofft filesizet maxprott initprott nsectst versiont sdkt platformt minost ntoolsc C s0 | d >d @| d >d @B| d ?d @B| d ?d @BS( Ni I � i i � i � i� ( ( t x( ( s8 /usr/lib/python2.7/site-packages/wheel/macosx_libfile.pyt swap32� s #c C s� | d k r | j � } n | j | � t j j | j t j t j � � � j } | t t t t g k r� t j d k r� t j } n t j } t | � } n t j } | j | � | | f S( Nt little( t Nonet tellt seekt ctypest c_uint32t from_buffer_copyt readt sizeoft valuet FAT_CIGAMt FAT_CIGAM_64t MH_CIGAMt MH_CIGAM_64t syst byteordert BigEndianStructuret LittleEndianStructureR t Structure( t lib_fileR t magic_numbert BaseClass( ( s8 /usr/lib/python2.7/site-packages/wheel/macosx_libfile.pyt get_base_class_and_magic_number� s ! c C s | j | j t j | � � � S( N( R# R$ R!
