Basic Installation
==================

The simplest way to compile the libraries or the provided softwares  is  to  run
one of the script beginnig with "build_". Each script permits to build different
parts of the framework, with different options. 

To compile EO you will need CMake and a compiler for your system.

So far the available scripts for posix systems using g++ are the following:
    * build_gcc_linux_release      : the most usefull script, build the core libraries in release mode
    * build_gcc_linux_debug        : build the core libraries with debugging informations in the binaries
    * build_gcc_linux_tutorial     : build the core libraries and the tutorials
    * build_gcc_linux_unittest     : build the core libraries and the tests executables
    * build_gcc_linux_stl_parallel : build the core libraries enabling STL parallel algorithms (like sorting)
    * build_gcc_linux_pyeo         : build the core libraries and the python module
    * distclean : remove the "release/" and "debug/" directories where the build scripts put the binaries

For Windows systems using Visual Studio:
    * build_vs2008_release.bat
        You may need to adapt the ID to your version of Visual Studio, edit
        the "Visual Studio 9 2008" string accordingly.

The libraries are in the "release/lib/" or "debug/lib/" directories.


Compilers and Options
=====================

The build scripts are really simple, take a look at them to see how to use the
build system.

Basically, the steps are:
    0. remove any old build directory that's on the way:
        rm -rf build/
    1. create a directory in which to put build files:
        mkdir build/
    2. go in this directory:
        cd build/
    3. call cmake with the options you want, using the "-D" option and passing the 
    EO directory as an argument, for example:
        cmake -DCMAKE_BUILD_TYPE=Debug -DENABLE_CMAKE_TESTING =1  ..
    4. now type your favorite "make" command, like:
        make -j # use several processors at once when possible
    5. enjoy:
        ./debug/test/t-eofitness

Some of the available options are:
    * CMAKE_BUILD_TYPE : 
        * "Debug" : embed debugging informations in the binaries) or
        * "Release" : no debugging info and some optimizations (the default)
    * ENABLE_EO_TUTORIAL : build the tutorial ("no" by default)
    * ENABLE_CMAKE_TESTING : build the tests executables ("no" by default)
    * ENABLE_PYEO : build the python module ("no" by default)

You can pass generic options to the compiler, like:
    * _GLIBCXX_PARALLEL : use the parallel version of the STL


Installation using packages
===========================

To construct a dummy template of the EO package you will need CPack.  Be  warned
that those  do  not  guarantee  correct  dependencies  and  version  management.

Use the "package_*" scripts:
    * package_deb : for debian-like systems
    * package_rpm : for red-hat-like systems

Or go through the following steps:
    1. go in the build directory where your binaries are:
        cd build/
    2. call CPack specifying the desired package system:
        cpack -G DEB
    3. install the package:
        sudo apt-get install EO-1.1.1-Linux.deb


Basic installation
==================

To install the framework system-wide, copy the "eo/" directory somewhere in  your
path.  The "lib/" directory should be reachable for the linker  and  the  "src/"
directory must be in the compiler include path.
