Display information about files in different file formats and find gadgets to build rop chains for different architectures (x86/x86_64, ARM/ARM64, MIPS, PowerPC, SPARC64). For disassembly ropper uses the awesome Capstone Framework.
When using the 'semantic' feature with python3 and 3.11 there are several library issues that I had on Linux.
1)
File "/usr/local/lib/python3.11/dist-packages/ropper-1.13.8-py3.11.egg/ropper/semantic.py", line 67, in analyse
irsb = pyvex.IRSB(bytes(gadget.bytes), gadget.address+thumb, gadget.arch.info, bytes_offset=thumb, num_bytes=len(gadget.bytes), opt_level=0)
^^^^^
NameError: name 'pyvex' is not defined
this one shows up even when you have installed pyvex. I solved it by moving the import pyvex out of the try except block in ropper/semantic.py
2)
solver = z3.Solver()
^^^^^^^^^
AttributeError: module 'z3' has no attribute 'Solver'
this showed even after install z3py as the README says and running python3 -m pip install z3
To solve it you need the z3-solver package: python3 -m pip install z3-solver
