Pyddd

Pyddd is a super-GDB debugger which could debug python scripts as the same way to debug c program line by line in the same inferior.

Download

You can also download a snapshot from the Git repository:

• as a .tar.gz <https://github.com/jondy/pyddd/archive/master.tar.gz>__ file or
• as a .zip <https://github.com/jondy/pyddd/archive/master.zip>__ file

Installation

Since Pyddd is written in the Python language, you need to install Python (the required version is at least 2.6).

Linux

• Rebuild GDB with Python and reinstall it.

.. code-block:: bash

$ tar xzf gdb-7.8.1.tar.gz $ cd gdb-7.8.1 $ ./configure --with-python=python --with-babeltrace=no
--enable-tui=no --enable-host-shared $ make && make install

• Extract Pyddd package, copy libddd.py to gdb data directory.

.. code-block:: bash

$ cp libddd.py /usr/local/share/gdb/python

• Build pyddd-ipa.

.. code-block:: bash

$ gcc -g -fPIC -I/usr/include/python2.7 -Wl,-lpthread -shared -o
python-ipa.so ipa.c $ cp python-ipa.so /usr/local/lib

Windows

• Install Cygwin.
• Rebuild GDB with Python in Cygwin and reinstall it.

.. code-block:: bash

$ tar xzf gdb-7.8.1.tar.gz $ cd gdb-7.8.1 $ ./configure --with-python=python --with-babeltrace=no
--enable-tui=no --enable-host-shared $ make && make install

• Unzip Pyddd package, copy libddd.py to gdb data directory.

.. code-block:: bash

$ cp libddd.py /usr/local/share/gdb/python

• Open Cygwin Terminal, build pyddd-ipa.

.. code-block:: bash

$ gcc -g -I/usr/include/python2.7 -Wl,-lpthread -shared -o
python-ipa.dll ipa.c $ cp python-ipa.dll /usr/local/lib

Quick Start

After installation, invoke the command prompt, go to the directory including the debugged script foo.py and run those commands (assume pyddd is extracted at /usr/local/pyddd):

.. code-block:: bash

$ gdb -x /usr/local/pyddd/init.gdb (gdb) py-exec-file python (gdb) py-file foo.py (gdb) py-start
