A Python (3.x compatible) interface to the GNU Binary File Descriptor (BFD) and opcodes library.

Project description


This clone of PyBFD mainly adds support for Python 3.x while keeping compatibility with Python 2.x. To prevent conflicts and possible confusion, the name of the module/package has changed to pybfd3

Because it seems that pybfd is no longer maintained, I decided to create my own independent repository.


Version 0.1.5

  • Remove legacy distutils usage (thanks to @Bidski)

Version 0.1.4

  • Update PyBFD3 to be compatible with binutils > 2.29 (thanks to @Bidski)


  • The binutils-dev package must be installed first.


Method 1: Via Python Package Index (PyPI).

$ pip install pybfd3

Method 2: Local installation.

$ git clone
$ pip install ./pybfd3


Depending on your pip version, you may need to add pip's --egg install option to successfully complete the installation.

Sample Session

$ cd pybfd3/examples
$ chmod +x
$ ./
Usage : ./ <binary>
$ ./ `which sudo`
