Project Status. We are now actively working on Olena 2.x only. Older versions are not maintained anymore.
The latest version is Olena 2.1. It is available since July 8, 2014. You will find more details on the dedicated Olena 2.1 release page.
All platforms (sources)

Building Olena for sources requires the following tools:
- A Bourne shell (/bin/sh)
- GNU Make (other versions of Make might work but have not been tested)
- A C++ 2003 compiler such as GCC version 4.2 or higher; or Clang version 3.0 or higher (other compilers might work but have not been tested)
Installing from sources
Once you have downloaded the Olena sources, extract, configure and compile the project using the following commands:
tar xjf olena-2.1.tar.bz2 cd olena-2.1 ./configure make
You can pass extra options to configure to enable optional modules of the platform, choose a different installation path (default is /usr/local) or change the compilation flags; use ./configure --help to get more details about these features.
Finally, install Olena using:
The defaut installation path (/usr/local) usually requires root permissions, so you'll probably want to run it through sudo (provided you have the permission to do so):
sudo make install
Alternatively, you can choose to install Olena in a location of your own, like a subdirectory of your home directory, such as $HOME/local, by following this recipe instead (note the addition of the --prefix option passed to configure):
tar xjf olena-2.1.tar.bz2 cd olena-2.1 ./configure --prefix=$HOME/local make make install
Olena is currently being integrated into Debian. However .deb files are already available :sudo dpkg -i olena-bin_2.0-1_amd64.deb olena-dev_2.0-1_all.deb Add Olena's repository and install the package:sudo add-apt-repository ppa:olena/ppa sudo apt-get update sudo apt-get install olena Olena is available in Mandriva Cooker mainstream:urpmi olena-devel olena-tools olena-doc
Packages are also available here: olena-tools olena-doc olena-doc
Mac OS X packages
Install Milena and the Scribo module:sudo port install olena
Or install Milena sources only :sudo port install olena -scribo
Once Olena is installed, development headers are available in /usr/include/mln and /usr/include/scribo.
Two program tools are also available : scribo-cli and scribo-viewer.
Olena 1.0 is also available in Mandriva Linux 2010.0 as RPM packages.
Some extra information about past versions of Olena can be found on the past releases page.
Getting the source from the development repository
You may check out the current version of Olena 2.0's sources from LRDE's Git repository. You will need the following additional tools:
- Git 1.5 or higher
- Autoconf 2.61 or higher
- Automake 1.10 or higher
- Libtool 1.5.22 or higher
- Doxygen 1.5.6 or higher
- ImageMagick 6.3.7 or higher
- HeVeA 1.10
- LaTeX2HTML (or at minimum, its html.sty style file)
- bibtex2html 1.95 or higher (at least the bibtex2html and bib2bib tools)
- Tesseract (2.0x, 3.01 or higher. Needed by the Scribo module only)
For those who are not used to Git, here are the required commands to get and build a fresh source tree:
git clone git://git.lrde.epita.fr/olena cd olena ./bootstrap mkdir _build cd _build ../configure --enable-verbose make
The last command may take some time.
To install Olena, type thereafter (as root):
Compilation issues may be encountered with g++ 4.6.0 and 4.6.1 (especially on Ubuntu 11.10) with Olena 2.0.
Here is an example of the possible error :
../../../../olena/milena/mln/canvas/browsing/snake_generic.hh:90:29: error: uninitialized const mln::canvas::browsing::snake_generic [-fpermissive] ../../../../olena/milena/mln/canvas/browsing/snake_generic.hh:76:14: note: const struct mln::canvas::browsing::snake_generic_t has no user-provided default constructor
Many non-relevant warnings may also arise.
A simple solution is to add CXXFLAGS to configure script with the following argument :
../configure CXXFLAGS="-fpermissive -Wunused-but-set-variable"
or pass these flags to any build task using Milena headers, e.g. when using Make :
make CXXFLAGS="-fpermissive -Wunused-but-set-variable"
Otherwise, using a different version of g++ would also fix this issue without specifying anything to configure.
