Before reporting a bug or asking a question, please check that your query is not covered by one of the above sources first.
To report a bug, please give us as much information as possible about the circumstances surrounding the problem. Sometimes it is necessary to send your Jutoh project file (.jutoh file) for us to look at. Over time, the file can get big, so before emailing it to us, compact the project by clicking on File and then Compact Project..
On Windows, if Jutoh crashes, you will be prompted for some notes and the automated bug report will be attached to an email message. We would be grateful for as much context as you can provide.
If Jutoh crashes on Mac, please click the Report button, select and copy the information in the problem report, and email it to us with a description of what command caused it. There is no need to send the crash report to Apple as it's unlikely they'll know what to do with it.
If you didn't click on the Report button, you can find the log from a previous crash. Crash log files are stored in different locations on different versions of Mac OS X:
On Linux, we would be grateful if you could run Jutoh under gdb and send us a stack trace of the problem.
To do this, fire up a terminal window e.g. with Ctrl+Alt+T, and check where Jutoh is installed. Do this by using the which command to tell you where the Jutoh runner script is; then view it, for example with the less viewer command. This will tell you where the actual installation folder is. Typically Jutoh is installed in /usr/share/jutoh or /opt/jutoh. Change directory to that folder and invoke gdb, and type run. For example:
% which jutoh % less /usr/bin/jutoh % cd /opt/jutoh % gdb jutoh % run % bt
Now if or when Jutoh crashes, copy and paste the stack trace (or at least the first few dozen lines of it) into an email along with a description of the sequence of commands that led to the crash.
