Debugging Program Crashes
See the section below if you are using an Ubuntu version prior to Edgy (6.10)
1. Add the following line to /etc/apt/sources.list:
deb http://people.ubuntu.com/~pitti/ddebs edgy main universe
2. Import Martin's public key to your keyring:
wget "http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x0DE7276D5E0577F2" -O - | sudo apt-key add -
3. Then run
sudo apt-get update
to update your package list.
4. The debug symbol packages have the -dbgsym suffix attached, so to install the debug symbols for the package yelp, you run:
sudo apt-get install yelp-dbgsym
- Now you make a ["Backtrace"].
- You can also run ["Valgrind"], if the program crashes with a "Segmentation fault" or "Bus error".
- Optionally, you may be asked to produce an ["Strace"].

Debugging Crash before Edgy
Use this section if you are using an Ubuntu version prior to Edgy (6.10)
Check if the package has a debugging version available. In general, debugging packages will be named with a -dbg suffix
- If not, you can generally* build one this way:
- Something to keep in mind: if you would like to create a build you're going to need to have the relevant deb-src lines in your /etc/apt/sources.list
Install the development scripts:
sudo apt-get install devscripts
Install the build-time dependencies for the package:
sudo apt-get build-dep <package>
Build .debs for debugging:
export DEB_BUILD_OPTIONS="debug nostrip noopt" fakeroot apt-get source -b <package>
Install the needed .debs (they will be in the current working directory if the build succeeded):
sudo debi <package>*.changes
* most of the packages support the build of debugging version in this way. If that doesn't work for a package you can open a bug against it.
