Line 1: Line 1:
 1. Check if the package has a debugging version available. In general, debugging packages will be named with a `-dbg` suffix
 1. If not, you can generally* build one this way:
  a. Install the development scripts: {{{
sudo apt-get install devscripts
}}}
  a. Install the build-time dependencies for the package: {{{
sudo apt-get build-dep <package>
}}}
  a. Build .debs for debugging: {{{
export DEB_BUILD_OPTIONS="nostrip noopt"
sudo apt-get source -b <package>
}}}
  a. Install the needed .debs (they will be in the current working directory if the build succeeded): {{{
sudo debi <package>*.changes
}}}
 1. Now you make a ["Backtrace"].
 1. You can also run ["Valgrind"], if the program crashes with a "Segmentation fault" or "Bus error".
 1. Optionally, you may be asked to produce an ["Strace"].

* 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.
