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/). 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 and demo subdirectories when enabled. 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-demo Build the examples in the demo subdirectory. --disable-demo Do not build the examples in the demo subdirectory (default). --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.
