Package variants

Cumulus is available for different environments.

Our current PDA environment is the Maemo OS to find on the Nokia Internet Tablets N800/N810/N900. Cumulus is running here together with the Qt4.x C++ class library from Qt Software former Trolltech. Furthermore Cumulus runs also under a normal Linux Desktop with Qt4/X11 installed.

Due to differences in OS, compilers, libraries and file system layout there are provided separate packages for the different Tablet hardwares. Please make sure you get the one suited for your system.

Refer to our help page for instructions on how to install these different package variants of Cumulus.

Cumulus 2.x

First released: March 2009

Cumulus 2.x.y is the current line based on Qt4.5.x C++ class library from Qt Software. It can be installed on the Nokia Internet tablets N800/N810/N900 running Maemo OS2008 Diablo, OS 2009 Fremantle or on a Linux desktop PC with X11/Qt4.x.

Packages for the Maemo OS carry the names

and are installable by using the program manager of the tablet. Go onto our download site, pickup the leatest release, download it to your tablet and install it there.

For the installation on the Linux desktop is only a makefile available, which builds and installs cumulus under the directory path /opt/cumulus.

Snapshots

If you want to hack on Cumulus, port it to a new platform or if you just want to use the bleeding edge of Cumulus, you can use our daily source snapshots. These snapshot are made automatically each night, directly from our subversion source code repository. You will have to compile Cumulus yourself. There are some clues on how to do that in the root of the source dirrectory but you'll have to provide a suitable toolchain yourself. On a Linux desktop you need only a X11 environment and the Qt4.x C++ class libraries from Qt Software, former Trolltech, to build Cumulus.

Tow different snapshot files are provided. One with name CumulusQt2-snapshot.tbz for the old Qtopia and Opie environment, currently not more maintained and the other one with name CumulusQt4-snapshot.tbz for the current Qt4/X11 environment. From the second file you can very easy build Cumulus for the Linux desktop.

From time to time we will provide also installable snapshot packages for you to test. We know the problems concerning setup an own integration environment but a daily automatic building of packages is currently not possible. Inspect our snapshot area to see what is available. Please note that these packages may be unstable.

If you make any modifications to Cumulus, please consider sending us a patch and some explanation on what you modified. We may incorporate it into the main release if it looks usefull to a wider public. Please see the getting involved page for more information.
