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 webpage (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 changes to the directory which was created when you extracted the sources. The x.y.z part is a version number. 2. `./configure' This runs the configure shell script, which does some checks and configuration (creates makefiles etc). 3. `make' This command compiles the non-template part of LEMON into libemon.a file. It also compiles the benchmark and demo programs 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 1. For example: `./configure --prefix=/home/username/lemon' Configure Flags =============== You can pass the following flags to configure in step 1 (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. --enable-demo Build the demo programs too. --disable-demo Do not build the demo programs (default). --enable-benchmark Build the benchmark programs too. --disable-benchmark Do not build the benchmark programs (default). --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.
