| 20 | \page getting_started How to Start Using LEMON |
| 21 | |
| 22 | In this page we detail how to start using LEMON, from downloading it to |
| 23 | your computer, through the steps of installation, to showing a simple |
| 24 | "Hello World" type program that already uses LEMON. We assume that you |
| 25 | have a basic knowledge of your operating system and C++ programming |
| 26 | language. The procedure is pretty straightforward, but if you have any |
| 27 | difficulties don't hesitate to |
| 28 | <a href="mailto:lemon-user@lemon.cs.elte.hu"><b>ask</b></a>. |
| 29 | |
| 30 | \section requirements_lemon Hardware and Software Requirements |
| 31 | |
| 32 | In LEMON we use C++ templates heavily, thus compilation takes a |
| 33 | considerable amount of time and memory. So some decent box would be |
| 34 | advantageous. But otherwise there are no special hardware requirements. |
| 35 | |
| 36 | You will need a recent C++ compiler. Our primary target is the GNU C++ |
| 37 | Compiler (g++), from version 3.3 upwards. We also checked the Intel C++ |
| 38 | Compiler (icc) and Microsoft Visual C++ .NET 2003, 2005. |
| 39 | If you want to develop with LEMON under Windows you could consider |
| 40 | using Cygwin. |
| 41 | |
| 42 | In this description we will suppose a Linux environment and GNU C++ Compiler. |
| 43 | |
| 44 | \subsection requirements_lp LP Solver Requirements |
| 45 | |
| 46 | The LEMON LP solver interface can use the GLPK (GNU Linear Programming |
| 47 | Kit), CPLEX (was tested with CPLEX 7.5) and SoPlex solver. If you want |
| 48 | to use it you will need at least one of these. See \ref configure_flags |
| 49 | how to enable these at compile time. |
| 50 | |
| 51 | \section download_lemon How to Download LEMON |
| 52 | |
| 53 | You can download LEMON from the LEMON web site: |
| 54 | <a href="http://lemon.cs.elte.hu/">https://lemon.cs.elte.hu/</a>. |
| 55 | There you will find released versions in form of <tt>.tar.gz</tt> files. |
| 56 | If you want a developer version (for example you want to contribute in |
| 57 | developing the library LEMON) then you might want to use our Mercurial |
| 58 | repository. This case is detailed later, so from now on we suppose that |
| 59 | you downloaded a <tt>.tar.gz</tt> file. |
| 60 | |
| 61 | \section install_lemon How to Install LEMON |
| 62 | |
| 63 | In order to install LEMON you have to do the following steps. |
| 64 | |
| 65 | Download the tarball (named <tt>lemon-x.y.z.tar.gz</tt> where \c x, \c y |
| 66 | and \c z are numbers indicating the version of the library, in our example |
| 67 | we will have <tt>lemon-1.0.tar.gz</tt>) and issue the following commands: |
| 68 | |
| 69 | \verbatim |
| 70 | tar xvzf lemon-1.0.tar.gz |
| 71 | cd lemon-1.0 |
| 72 | ./configure |
| 73 | make |
| 74 | make check # This is optional, but recommended. It runs a bunch of tests. |
| 75 | make install |
| 76 | \endverbatim |
| 77 | |
| 78 | These commands install LEMON under \c /usr/local (you will |
| 79 | need root privileges to be able to install to that |
| 80 | directory). If you want to install it to some other place, then |
| 81 | pass the \c --prefix=DIRECTORY flag to <tt>./configure</tt>, for example: |
| 82 | |
| 83 | \verbatim |
| 84 | ./configure --prefix=/home/username/lemon |
| 85 | \endverbatim |
| 86 | |
| 87 | In what follows we will assume that you were able to install to directory |
| 88 | \c /usr/local, otherwise some extra care is to be taken to use the library. |
| 89 | |
| 90 | We briefly explain these commands below. |
| 91 | |
| 92 | \verbatim |
| 93 | tar xvzf lemon-1.0.tar.gz |
| 94 | \endverbatim |
| 95 | This command untars the <tt>tar.gz</tt> file into a directory named |
| 96 | <tt>lemon-1.0</tt>. |
| 97 | |
| 98 | \verbatim |
| 99 | cd lemon-1.0 |
| 100 | \endverbatim |
| 101 | This command enters the directory. |
| 102 | |
| 103 | \verbatim |
| 104 | ./configure |
| 105 | \endverbatim |
| 106 | This command runs the configure shell script, which does some checks and |
| 107 | creates the makefiles. |
| 108 | |
| 109 | \verbatim |
| 110 | make |
| 111 | \endverbatim |
| 112 | This command compiles the non-template part of LEMON into <tt>libemon.a</tt> |
| 113 | file. It also compiles the programs in the tools and demo subdirectories |
| 114 | when enabled. |
| 115 | |
| 116 | \verbatim |
| 117 | make check |
| 118 | \endverbatim |
| 119 | This step is optional, but recommended. It runs the test programs that |
| 120 | we developed for LEMON to check whether the library works properly on |
| 121 | your platform. |
| 122 | |
| 123 | \verbatim |
| 124 | make install |
| 125 | \endverbatim |
| 126 | This command will copy the directory structure to its final destination |
| 127 | (e.g. to \c /usr/local) so that your system can access it. |
| 128 | This command should be issued as "root", unless you provided a |
| 129 | \c --prefix switch to the \c configure to install the library in |
| 130 | non-default location. |
| 131 | |
| 132 | Several other configure flags can be passed to <tt>./configure</tt>. |
| 133 | For more information see <tt>./configure --help</tt> and the INSTALL |
| 134 | file in the install directory. |
| 135 | |
| 136 | \section hg_checkout How to Checkout LEMON from our Mercurial Repository |
| 137 | |
| 138 | You can obtain the latest version of LEMON from our Mercurial repository. |
| 139 | To do this issue the following command: |
| 140 | \verbatim |
| 141 | hg clone http://lemon.cs.elte.hu/hg/lemon lemon-src |
| 142 | \endverbatim |
| 143 | |
| 144 | \section hg_compile How to Compile the Source from the Repository |
| 145 | |
| 146 | You can compile the code from the repository similarly to the packaged |
| 147 | version, but you will need to run <b><tt>autoreconf -vif</tt></b> or |
| 148 | <b><tt>./bootstrap</tt></b> in some older environment before |
| 149 | <tt>./configure</tt>. See <tt>./configure --help</tt> for options. |
| 150 | For bootstrapping you will need the following tools: |
| 151 | |
| 152 | - <a href="http://www.gnu.org/software/automake/">automake</a> (1.7 or newer) |
| 153 | - <a href="http://www.gnu.org/software/autoconf/">autoconf</a> (2.59 or newer) |
| 154 | - <a href="http://www.gnu.org/software/libtool/">libtool</a> |
| 155 | - <a href="http://pkgconfig.freedesktop.org/">pkgconfig</a> |
| 156 | |
| 157 | To generate the documentation, run <tt>make html</tt>. |
| 158 | You will need <a href="http://www.doxygen.org/">Doxygen</a> for this. |
