A library for building COFF object files.
Tutorial
Start with the ObjectModule class:
module = ObjectModule()
Now, let’s create a ‘.text’ section:
section = Section(b'.text', SectionFlags.MEM_EXECUTE)
Add a bit of code:
section.data = b'\x29\xC0\xC3' # return 0 section.size_of_raw_data = len(section.data)
Good enough, let’s add it to our module:
module.sections.append(section)
To make use of that bit of code, we are going to need an exported symbol:
main = SymbolRecord(b'main', section_number=1, storage_class=StorageClass.EXTERNAL)
Set the value to the offset in the section:
main.value = 0
And add it to our module:
module.symbols.append(main)
That’s enough, let’s write our module to a file:
with open('test.obj', 'wb') as obj_file:
obj_file.write(module.get_buffer())
