You can also grab the <a href="http://www.jnchen.com/_media/projects/mozilla/moz-gdb.tar.bz2" class="media mediafile mf_bz2 wikilink2" title="projects:mozilla:moz-gdb.tar.bz2">pre-built Linux tarball</a>. Note that the pre-built binaries require libpython2.7. </p> <h3><a name="gdb" id="gdb" href="http://www.jnchen.com/blog/2011/11/updated-gdb">gdb</a></h3> <div class="level3"> <p> The updated gdb is faster when setting up remote debugging. Sometimes it can get pretty frustrating when you have to debug a lot of sessions, and you have to wait half a minute each time just to get started. This update will hopefully make it a little better. (This is not an issue if you have an intern at your disposal ;) </p> </div> <h3 class="sectionedit7"><a name="gdbutils" id="gdbutils">gdbutils</a></h3> <div class="level3"> <p> <a href="https://github.com/darchons/android-gdbutils" class="urlextern" title="https://github.com/darchons/android-gdbutils" rel="nofollow">gdbutils</a> is a set of Python scripts that works with Android gdb. The updated gdbutils includes the following modules: </p> </div> <h4><a name="feninit" id="feninit">feninit</a></h4> <div class="level4"> <p> feninit automatically sets up the debug environment. The updated version adds support for B2G (see gdbinit for details; thanks ThinkerYzu!) and various bug fixes. </p> </div> <h4><a name="tracebt" id="tracebt">tracebt</a></h4> <div class="level4"> <p> tracebt is a stack unwinder that works by tracing assembly. The updated version adds a sanity check to stop unwinding before the script gets stuck somewhere and becomes depressed. </p> </div> <h4><a name="fastload" id="fastload">fastload</a></h4> <div class="level4"> <p> fastload is a new module that automatically pulls system libraries from the device in the background. This way you don&#039;t have to wait minutes just to download system libraries when debugging on a new device. </p> </div> <h4><a name="adblog" id="adblog">adblog</a></h4> <div class="level4"> <p> adblog is a new module that redirects the output of &#039;adb logcat&#039; to the gdb terminal when Fennec is running. It also colorizes the logs according to the order they arrived, their priority, or the threads that generated them, like this: </p> <p> <a href="http://www.jnchen.com/_media/blog/2011/10/adblog.png" class="media" title="blog:2011:10:adblog.png"><img src="http://www.jnchen.com/_media/blog/2011/10/adblog.png?w=500" class="mediacenter" title="adblog example" alt="adblog example" width="500" /></a> </p> <p> You can find additional documentation for gdbutils in the <a href="https://github.com/darchons/android-gdbutils/blob/master/README.md" class="urlextern" title="https://github.com/darchons/android-gdbutils/blob/master/README.md" rel="nofollow">README</a>.
