macholib can be used to analyze and edit Mach-O headers, the executable format used by Mac OS X. It's typically used as a dependency analysis tool, and also to rewrite dylib references in Mach-O headers to be @executable_path relative. Though this tool targets a platform specific file format, it is pure python code that is platform and endian independent.

-m macholib.MachOGraph doesn't output much #34

Open altendky opened 4 years ago

altendky commented 4 years ago

python -m macholib.MachOGraph doesn't seem to provide much output despite otool -L providing several system and relative path libraries. Is it missing something?

My (next layer out) actual goal is to take a given executable or bundle and list out absolute paths to all 'libraries' it would link to if run (recursively) . This is part of https://github.com/altendky/pyqt5-tools/pull/43 where I am trying to collect many Qt applications and package them into a wheel.

Thanks for the library and any help with this scenario.

It took a bit of tinkering, but I arrived at a process for generating Graphviz documents. Try this:

from macholib import MachO, MachOGraph
from altgraph import Dot

m = MachO.MachO("/bin/ls")
g = MachOGraph.MachOGraph()
g.run_file(m.filename)
# remove top-level graph node
g.removeNode(g.graph.node_list()[0])
dot = Dot.Dot(g.graph)
dot.save_dot("ls.dot")
dot.save_img("ls", file_type="pdf")

... and here's the resulting PDF: ls.pdf
