Please note that published packages may contain bugs. We are not able to test them in all details.
Internet tablet packages are installable by using the program manager of the tablet. Go onto our download site, pickup the latest release, download it to your tablet and install it there.
For Linux Ubuntu and Debian installable binary packages are provided under this link.
For the installation on other Linux desktops are Debian source packages or only a Makefile available, which builds and installs cumulus under the directory path /opt/cumulus.
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 snapshot file with the name CumulusQt4-snapshot.tbz. This snapshot is made automatically each night, directly from our subversion source code repository. You will have to compile Cumulus yourself. There is an instruction file INSTALL to find in the root of the source directory but you’ll have to provide a suitable toolchain yourself. On a Linux desktop you need only a X11 environment and the Qt4.7 C++ class libraries or higher from qt-project.org to build Cumulus.
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 useful to a wider public. Please see the getting involved page for more information.
Cumulus sources are stored in a git repository at GitHub. The ULR to the repository is:
Get a copy of our git repository into your local environment by issuing the command git clone https://github.com/kflog-project/Cumulus.git. You do not need special access rights for that.
