During these three years, the prototype was used +to experiment with genericity and to try to meet our objectives. +In February 2007, Olena 0.11 was released to conform modern C++ compilers. +At that time, the code was not enough readable though and the compilation time +was too long. + +Since June 2007 up to now, The library of the Olena platform is called Milena +and the library has been rewritten. The programming paradigm has been +simplified: the code is more readable and the compilation time is acceptable. +The level of genericity still meets our objectives though. + +Milena is now getting ready for being considered as stable and distributable. +The core of the library is getting frozen and we aim at enriching the library, +its documentation and the related tools. + + +%************************** +\doxysection{tuto1contacts}{Contacts} + +If you want to reach us directly, you can contact one of the following people: + +\begin{itemize} + \item Thierry Geraud - Project Manager - thierry.geraud(a)lrde.epita.fr +\end{itemize} + + + + + + +%\begin{htmlonly} %==================================== -\doxychapter{tuto1}{Step 1: Load and save images} +\doxychapter{tuto2}{Installation} + +%pre-requis/compatibility +This section describes the installation process of Milena. +Do not forget that Milena is a library, not a program. Therefore, no program +will be installed. + +Milena's examples and tests are compiled on the following platforms: +\begin{itemize} + \item Apple Tiger Darwin 8, PowerPC, GCC 4.0.1 + \item Apple Leopard Darwin 10.5, X86-64, GCC 4.0.1, 4.2 + \item Linux, i486, GCC 3.3, 4.1, 4.2, 4.3 + \item Linux, x86-64, GCC 4.1 +\end{itemize} + +We guaranty that Milena compiles on these platforms, e.g. Linux and Unix +platforms. It may compiles on other platforms though but we have not tested. +If you did, and you succeeded, please let us know in order to update this +section. + +Milena is known NOT to work with GCC-2.95. + + +Milena is actively developed under Unix systems. As a result, the build system +is based on the Autotools. +Autotools make sure that every dependencies are resolved before compiling +or installing a program. + +Milena is different from usual libraries in a way that nothing needs to be +compiled to use it. The library itself is composed of headers which must be +included when you need them. +Then, your application will be compiled with the parts of the library used in +that program. That's all. + +So, why do we have a build system? It is useful for installing the library on +your system, generating the doc and compiling the test suite and the examples. + + + +%************************** +\doxysection{tuto2bootstrap}{Bootstrap (SVN Sources)} + +If you got the sources from a package/tarball, you can skip this section. Go +to section \ref{tuto2configure}. + +If you downloaded the sources from the SVN repository, you must launch a +script before configuring the build directory. + +Run the following: +\begin{verbatim} +$ cd /my/path/to/olena-1.0 +$ ./bootstrap +\end{verbatim} + +Running 'bootstrap' can take a while. Some files are generated during this +process. +When it's done, you are ready to configure the build directory. + + + +%************************** +\doxysection{tuto2configure}{Configure} + +First, make sure you are at the root directory of the milena source: + +\begin{verbatim} +$ cd /my/path/to/olena-1.0 +\end{verbatim} + +First, create and enter a build directory: +\begin{verbatim} +$ mkdir build +$ cd build +\end{verbatim} + +We are now about to configure the build directory. This process will create +the necessary files to compile documentation, examples and tools and prepare the +installation. + +\textbf{Important Note}: the Install path prefix must be chosen at this step. +By default, Milena will be installed in /usr/local but you may like to install +it elsewhere. To do so, pass the option \textit{--prefix=/installation/path/prefix} +to the configure script (see below). Replace '/installation/path/prefix' with the +wanted installation path prefix. + +now, you can run: +\begin{verbatim} +$ ../configure +\end{verbatim} +OR +\begin{verbatim} +$ ../configure --prefix=/installation/path/prefix +\end{verbatim} + +The configure script will perform various tests. If there is no dependency +issues, the last lines shown before the prompt are: + +\begin{verbatim} +config.status: creating config.h +config.status: executing depfiles commands +$ +\end{verbatim} + +The build directory is now configured, the library can be installed. + + + +%************************** +\doxysection{tuto2install}{Install} + +First, be sure to be in the build directory.
