This module contains function to analyse dynamic library
|
headers to extract system information
|
|
Currently only for MacOSX
|
|
Library file on macosx system starts with Mach-O or Fat field.
|
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 built 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.
|
- The system compile will set the deployment target no lower than
|
11.0 for arm64 builds. For "Universal 2" builds use the x86_64 deployment
|
target when the arm64 target is 11.0.
