QuarkslaB Dynamic Loader
The QuarkslaB Dynamic Linker (QBDL) library aims at providing a modular and portable way to dynamically load and link binaries.

Quick example
Here is a quick example using the Python API to run simple MachO binaries under Linux:
import pyqbdl
import lief
import sys
import ctypes
class TargetSystem(pyqbdl.engines.Native.TargetSystem):
def __init__(self):
super().__init__(pyqbdl.engines.Native.memory())
self.libc = ctypes.CDLL("libc.so.6")
def symlink(self, loader: pyqbdl.Loader, sym: lief.Symbol) -> int:
if not sym.name.startswith("_"):
return 0
ptr = getattr(self.libc, sym.name[1:], 0)
if ptr != 0:
ptr = ctypes.cast(ptr, ctypes.c_void_p).value
return ptr
loader = pyqbdl.loaders.MachO.from_file(sys.argv[1], pyqbdl.engines.Native.arch(), TargetSystem(),
pyqbdl.Loader.BIND.NOW)
main_type = ctypes.CFUNCTYPE(ctypes.c_int, ctypes.c_int, ctypes.c_voidp)
main_ptr = main_type(loader.entrypoint)
main_ptr(0, ctypes.c_void_p(0))For more detailed use cases, please refer to the documentation.
