All platforms (sources)

Version	Release date	Source code links		Release notes
Olena 2.0	September 16, 2011	olena-2.0.tar.gz	olena-2.0.tar.bz2	README-2.0	NEWS-2.0

Build requirements

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:

1  tar xjf olena-2.0.tar.bz2
2  cd olena-2.0
3  ./configure
4  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:

1  make install

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):

1  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):

1  tar xjf olena-2.0.tar.bz2
2  cd olena-2.0
3  ./configure --prefix=$HOME/local
4  make
5  make install

GNU/Linux packages

	Olena is currently being integrated into Debian. However .deb files are already available : olena-bin.deb (for Debian testing wheezy, AMD64 only) olena-bin.deb (for Debian testing wheezy, AMD64 only) olena-dev.deb (any Debian version) olena-dev.deb (any Debian version) 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: [[1]] [[2]] [[3]] 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.

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) The Git repository is located at git://git.lrde.epita.fr/olena. You can browse it online via GitWeb. For those who are not used to Git, here are the required commands to get and build a fresh source tree: 1git clone git://git.lrde.epita.fr/olena 2cd olena 3./bootstrap 4mkdir _build 5cd _build 6../configure --enable-verbose 7make The last command may take some time. To install Olena, type thereafter (as root): 1make install Known issues 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 : 1../configure CXXFLAGS="-fpermissive -Wunused-but-set-variable" or pass these flags to any build task using Milena headers, e.g. when using Make : 1make CXXFLAGS="-fpermissive -Wunused-but-set-variable" Otherwise, using a different version of g++ would also fix this issue without specifying anything to configure.
