| | Core dumps can be quite handy when debugging, but generally these are turned off to avoid wasting disk space. To turn them back on, edit ''/etc/security/limits.conf'' and add these lines: |
| | |
| | <file> |
| | * hard core unlimited |
| | * soft core unlimited |
| | </file> |
| | |
| | Reboot your machine and core dumps should be enabled. Confirm with the ''ulimit'' command: |
| | |
| | $ ulimit -c |
| | unlimited |

| If you have a machine with multiple cores (who doesn't these days?) you probably want to add this to the end of your .bashrc file to tell make that it can run multiple jobs simultaneously: | If you have a machine with multiple cores (who doesn't these days?) you probably want to add this to the end of your .bashrc file to tell make that it can run multiple jobs simultaneously: |

| This will make sure any Qt warnings stop the run so you will notice them and fix them. This is really helpful when working with signals and slots since the compiler has no idea whether the names of signals and slots actually exist. Downside: there is a slight chance that this will cause Qt apps (built in debug mode) to crash when run from the command line. | This will make sure any Qt warnings stop the run so you will notice them and fix them.

Removing QT_FATAL_WARNINGS for now. Retest at the next Ubuntu LTS release.]// |

| By default, Eclipse limits debug console output to 80,000 bytes. Rosegarden generates a lot of debug output. It's a good idea to turn this limit off. Go to Window > Preferences > Run/Debug > Console. Uncheck "Limit console output". | By default, Eclipse limits debug console output to 80,000 bytes. Rosegarden generates a lot of debug output.
