Installation Instructions

 =========================

 Since you are reading this I assume you already obtained one of the release

 tarballs and successfully extracted it. The latest version of LEMON is

 available at our web page (http://lemon.cs.elte.hu/).

 LEMON provides two different build environments, one is based on "autotool",

 while the other is based on "cmake". This file contains instructions only for

 the former one, which is the recommended build environment on Linux, Mac OSX

 and other unices or if you use Cygwin on Windows. For cmake installation

 instructions visit http://lemon.cs.elte.hu.

 In order to install LEMON from the extracted source tarball you have to

 issue the following commands:

    1. `cd lemon-x.y.z'

       This command changes to the directory which was created when you

       extracted the sources. The x.y.z part is a version number.

    2. `./configure'

       This command runs the configure shell script, which does some checks and

       creates the makefiles.

    3. `make'

       This command compiles the non-template part of LEMON into libemon.a

       file. It also compiles the programs in the tools subdirectory by

       default.

    4. `make check'

       This step is optional, but recommended. It runs the test programs that

       we developed for LEMON to check whether the library works properly on

       your platform.

    5. `make install'

       This command installs LEMON under /usr/local (you will need root

       privileges to be able to do that). If you want to install it to some

       other location, then pass the --prefix=DIRECTORY flag to configure in

       step 2. For example: `./configure --prefix=/home/username/lemon'.

    6. `make install-html'

       This command installs the documentation under share/doc/lemon/docs. The

       generated documentation is included in the tarball. If you want to

       generate it yourself, then run `make html'. Note that for this you need

       to have the following programs installed: Doxygen, Graphviz, Ghostscript,

       Latex.

 Configure Options and Variables

 ===============================

 In step 2 you can customize the actions of configure by setting variables

 and passing options to it. This can be done like this:

 `./configure [OPTION]... [VARIABLE=VALUE]...'

 Below you will find some useful variables and options (see `./configure --help'

 for more):

 CXX='comp'

   Change the C++ compiler to 'comp'.

 CXXFLAGS='flags'

   Pass the 'flags' to the compiler. For example CXXFLAGS='-O3 -march=pentium-m'

   turns on generation of aggressively optimized Pentium-M specific code.

 --prefix=PREFIX

   Set the installation prefix to PREFIX. By default it is /usr/local.

 --enable-tools

    Build the programs in the tools subdirectory (default).

 --disable-tools

    Do not build the programs in the tools subdirectory.

 --with-glpk[=PREFIX]

    Enable GLPK support (default). You should specify the prefix too if

    you installed GLPK to some non-standard location (e.g. your home

    directory). If it is not found, GLPK support will be disabled.

 --with-glpk-includedir=DIR

    The directory where the GLPK header files are located. This is only

    useful when the GLPK headers and libraries are not under the same

    prefix (which is unlikely).

 --with-glpk-libdir=DIR

    The directory where the GLPK libraries are located. This is only

    useful when the GLPK headers and libraries are not under the same

    prefix (which is unlikely).

 --without-glpk

    Disable GLPK support.

 --with-cplex[=PREFIX]

    Enable CPLEX support (default). You should specify the prefix too

    if you installed CPLEX to some non-standard location

    (e.g. /opt/ilog/cplex75). If it is not found, CPLEX support will be

    disabled.

 --with-cplex-includedir=DIR

    The directory where the CPLEX header files are located. This is

    only useful when the CPLEX headers and libraries are not under the

    same prefix (e.g.  /usr/local/cplex/cplex75/include).

 --with-cplex-libdir=DIR

    The directory where the CPLEX libraries are located. This is only

    useful when the CPLEX headers and libraries are not under the same

    prefix (e.g.

    /usr/local/cplex/cplex75/lib/i86_linux2_glibc2.2_gcc3.0/static_pic_mt).

 --without-cplex

    Disable CPLEX support.

 --with-soplex[=PREFIX]

    Enable SoPlex support (default). You should specify the prefix too if

    you installed SoPlex to some non-standard location (e.g. your home

    directory). If it is not found, SoPlex support will be disabled.

 --with-soplex-includedir=DIR

    The directory where the SoPlex header files are located. This is only

    useful when the SoPlex headers and libraries are not under the same

    prefix (which is unlikely).

 --with-soplex-libdir=DIR

    The directory where the SoPlex libraries are located. This is only

    useful when the SoPlex headers and libraries are not under the same

    prefix (which is unlikely).

 --without-soplex

    Disable SoPlex support.

 --with-coin[=PREFIX]

    Enable support for COIN-OR solvers (CLP and CBC). You should

    specify the prefix too. (by default, COIN-OR tools install

    themselves to the source code directory). This command enables the

    solvers that are actually found.

 --with-coin-includedir=DIR

    The directory where the COIN-OR header files are located. This is

    only useful when the COIN-OR headers and libraries are not under

    the same prefix (which is unlikely).

 --with-coin-libdir=DIR

    The directory where the COIN-OR libraries are located. This is only

    useful when the COIN-OR headers and libraries are not under the

    same prefix (which is unlikely).

 --without-coin

    Disable COIN-OR support.

 Makefile Variables

 ==================

 Some Makefile variables are reserved by the GNU Coding Standards for

 the use of the "user" - the person building the package. For instance,

 CXX and CXXFLAGS are such variables, and have the same meaning as

 explained in the previous section. These variables can be set on the

 command line when invoking `make' like this:

 `make [VARIABLE=VALUE]...'

 WARNINGCXXFLAGS is a non-standard Makefile variable introduced by us

 to hold several compiler flags related to warnings. Its default value

 can be overridden when invoking `make'. For example to disable all

 warning flags use `make WARNINGCXXFLAGS='.

 In order to turn off a single flag from the default set of warning

 flags, you can use the CXXFLAGS variable, since this is passed after

 WARNINGCXXFLAGS. For example to turn off `-Wold-style-cast' (which is

 used by default when g++ is detected) you can use

 `make CXXFLAGS="-g -O2 -Wno-old-style-cast"'.
