alpar@5: Installation Instructions
alpar@5: =========================
alpar@5: 
alpar@5:    Since you are reading this I assume you already obtained one of the release
alpar@5: tarballs and successfully extracted it. The latest version of LEMON is
alpar@5: available at our webpage (http://lemon.cs.elte.hu/).
alpar@5: 
alpar@5:    In order to install LEMON from the extracted source tarball you have to
alpar@5: issue the following commands:
alpar@5: 
alpar@5:   1. `cd lemon-x.y.z'
alpar@5: 
alpar@5:      This changes to the directory which was created when you extracted the
alpar@5:      sources. The x.y.z part is a version number.
alpar@5: 
alpar@5:   2. `./configure'
alpar@5: 
alpar@5:      This runs the configure shell script, which does some checks and
alpar@5:      configuration (creates makefiles etc).
alpar@5: 
alpar@5:   3. `make'
alpar@5: 
alpar@5:      This command compiles the non-template part of LEMON into libemon.a file.
alpar@5:      It also compiles the benchmark and demo programs when enabled.
alpar@5: 
alpar@5:   4. `make check'
alpar@5: 
alpar@5:      This step is optional, but recommended. It runs the test programs that we
alpar@5:      developed for LEMON to check whether the library works properly on your
alpar@5:      platform.
alpar@5: 
alpar@5:   5. `make install'
alpar@5: 
alpar@5:      This command installs LEMON under /usr/local (you will need root
alpar@5:      privileges to be able to do that). If you want to install it to some
alpar@5:      other location, then pass the --prefix=DIRECTORY flag to configure in
alpar@5:      step 1. For example: `./configure --prefix=/home/username/lemon'
alpar@5: 
alpar@5: 
alpar@5: Configure Flags
alpar@5: ===============
alpar@5: 
alpar@5:    You can pass the following flags to configure in step 1
alpar@5: (see ./configure --help for more):
alpar@5: 
alpar@5: CXX=comp
alpar@5: 
alpar@5:   Change the C++ compiler to 'comp'.
alpar@5: 
alpar@5: CXXFLAGS='flags'
alpar@5: 
alpar@5:   Pass the 'flags' to the compiler. For example
alpar@5:   CXXFLAGS='-O3 -march=pentium-m'
alpar@5:   turns  on generation of aggressively optimized
alpar@5:   Pentium-M specific code.
alpar@5: 
alpar@5: --enable-demo
alpar@5: 
alpar@5:    Build the demo programs too.
alpar@5: 
alpar@5: --disable-demo
alpar@5: 
alpar@5:    Do not build the demo programs (default).
alpar@5: 
alpar@5: --enable-benchmark
alpar@5: 
alpar@5:    Build the benchmark programs too.
alpar@5: 
alpar@5: --disable-benchmark
alpar@5: 
alpar@5:    Do not build the benchmark programs (default).
alpar@5: 
alpar@5: --with-glpk[=PREFIX]
alpar@5: 
alpar@5:    Enable GLPK support (default). You should specify the prefix too if
alpar@5:    you installed GLPK to some non-standard location (e.g. your home
alpar@5:    directory). If it is not found, GLPK support will be disabled.
alpar@5: 
alpar@5: --with-glpk-includedir=DIR
alpar@5: 
alpar@5:    The directory where the GLPK header files are located. This is only
alpar@5:    useful when the GLPK headers and libraries are not under the same
alpar@5:    prefix (which is unlikely).
alpar@5: 
alpar@5: --with-glpk-libdir=DIR
alpar@5: 
alpar@5:    The directory where the GLPK libraries are located. This is only
alpar@5:    useful when the GLPK headers and libraries are not under the same
alpar@5:    prefix (which is unlikely).
alpar@5: 
alpar@5: --without-glpk
alpar@5: 
alpar@5:    Disable GLPK support.
alpar@5: 
alpar@5: --with-cplex[=PREFIX]
alpar@5: 
alpar@5:    Enable CPLEX support (default). You should specify the prefix too
alpar@5:    if you installed CPLEX to some non-standard location
alpar@5:    (e.g. /opt/ilog/cplex75). If it is not found, CPLEX support will be
alpar@5:    disabled.
alpar@5: 
alpar@5: --with-cplex-includedir=DIR
alpar@5: 
alpar@5:    The directory where the CPLEX header files are located. This is
alpar@5:    only useful when the CPLEX headers and libraries are not under the
alpar@5:    same prefix (e.g.  /usr/local/cplex/cplex75/include).
alpar@5: 
alpar@5: --with-cplex-libdir=DIR
alpar@5: 
alpar@5:    The directory where the CPLEX libraries are located. This is only
alpar@5:    useful when the CPLEX headers and libraries are not under the same
alpar@5:    prefix (e.g.
alpar@5:    /usr/local/cplex/cplex75/lib/i86_linux2_glibc2.2_gcc3.0/static_pic_mt).
alpar@5: 
alpar@5: --without-cplex
alpar@5: 
alpar@5:    Disable CPLEX support.
