The adress of our bug tracker is:
There you can report bugs, submit feature requests, patches, or request to merge your branch if you developed something using git. The tracker is divided into modules, so please be specific and file your request in the appropriate subsection. In cas of doubt, leave it in the "FreeCAD" section.
If you think you might have found a bug, you are welcome to report it there. But before reporting a bug, please check the following items:
- Make sure your bug is really a bug, that is, something that should be working and that is not working. If you are not sure, don't hesitate to explain your problem on the forum and ask what to do.
- Before submitting anything, read the frequently asked questions, do a search on the forum, and make sure the same bug hasn't been reported before, by doing a search on the bug tracker.
- Describe as clearly as possible the problem, and how it can be reproduced. If we can not verify the bug, we might not be able to fix it.
- Join the following information: Your operating system, if it is 32 or 64 bits, and the version of FreeCAD you are running.
- Please file one separate report for each bug.
- If you are on a linux system and your bug causes a crash in FreeCAD, you can try running a debug backtrace: From a terminal run gdb freecad (assuming package gdb is installed), then, inside gdb, type run . FreeCAD will then run. After the crash happens, type bt , to get the full backtrace. Include that backtrace in your bug report.
If you want something to appear in FreeCAD that is not implemented yet, it is not a bug but a feature request. You can also submit it on the same tracker (file it as feature request instead of bug), but keep in mind there are no guarantees that your wish will be fulfilled.
In case you have programmed a bug fix, an extension or something else that can be of public use in FreeCAD, create a patch using the Git diff tool and submit it on the same tracker (file it as patch).
If you have created a git branch containing changes that you would like to see merged into the FreeCAD code, you can ask there to have your branch reviewed and merged if the FreeCAD developers are OK with it. You must first publish your branch to a public git repository (github,bitbucket, sourceforge...) and then give the URL of your branch in your merge request.
