| |
| <p><a name="index-python-scripting-1836"></a><a name="index-scripting-with-python-1837"></a> |
| You can extend <span class="sc">gdb</span> using the <a href="http://www.python.org/">Python programming language</a>. This feature is available only if |
| <span class="sc">gdb</span> was configured using <samp><span class="option">--with-python</span></samp>. |
| <span class="sc">gdb</span> can be built against either Python 2 or Python 3; which |
| one you have depends on this configure-time option. |
| |
| <p><a name="index-python-directory-1838"></a>Python scripts used by <span class="sc">gdb</span> should be installed in |
| <samp><var>data-directory</var><span class="file">/python</span></samp>, where <var>data-directory</var> is |
| the data directory as determined at <span class="sc">gdb</span> startup (see <a href="Data-Files.html#Data-Files">Data Files</a>). |
| This directory, known as the <dfn>python directory</dfn>, |
| is automatically added to the Python Search Path in order to allow |
| the Python interpreter to locate all scripts installed at this location. |
| |
| <p>Additionally, <span class="sc">gdb</span> commands and convenience functions which |
| are written in Python and are located in the |
| <samp><var>data-directory</var><span class="file">/python/gdb/command</span></samp> or |
| <samp><var>data-directory</var><span class="file">/python/gdb/function</span></samp> directories are |
| automatically imported when <span class="sc">gdb</span> starts. |
