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