Frequently asked questions

On this page, you will find answers to general questions concerning cedar. If you are having trouble compiling or running cedar, please take a look at the troubleshooting file that is shipped with your copy of cedar.

Is cedar free?

cedar is open source software, meaning the source code is freely available and can be copied and modified as long as the resulting product remains free under the same license. Additionally, cedar can be used without paying for it and is thus also free as in "free beer".

What operating systems does cedar support?

Currently, we mainly support Debian and Ubuntu (Linux). We also regularly compile on MacOSX, and sometimes on Windows. We plan to fully support the latter two operating systems in the near future.

Which license does cedar use?

cedar is distributed under the GNU LGPLv3.

Where do you get your money?

cedar is developed as part of the European Union Seventh Framework Programme FP7-ICT-2009-6 under grant agreement no. 270247 - NeuralDynamics.

Why did the release date of a new version already pass and there is no new version?

The release dates given in the download section are rough estimates, which may be adjusted along the process of releasing a new version. Although all core developers of cedar do not work full-time on cedar (in fact, for most of us it is more of a side project), we work hard to bring you new and improved versions of our software - sometimes sooner, sometimes later.

What happened to the cedar repositories stable, testing, and unstable?

We have decided to streamline our release process, so you do not have to wait a year in-between releases. We now only feature two repositories: release and development. You should only use the release repository.

What is the meaning of your version numbers? X.Y.Z?

The number X marks a major named release, Y indicates the number of new features since release of version X, and Z is the number of bug fixes since we added the Yth feature.

I would like to contribute to the project, how can I help?
