GCG is an optimization tool based on SCIP. This document is a description of what is needed to get compile GCG.
The latest GCG release and the official documentation can be found under http://www.or.rwth-aachen.de/gcg.
In order to compile GCG, you need
- SCIP Optimization Suite >= 3.1.0
and optionally
- bliss >= 0.72 (Direct download)
- readline-devel
- zlib-devel
- CPLEX >= 12.4.1
Install the required system libraries and tools for your Linux distribution:
Ubuntu
sudo apt-get install build-essential libreadline-dev libz-dev
OpenSuSE
sudo zypper in -t pattern devel_C_C++ && sudo zypper in readline-devel zlib-devel-static
CentOs (RHEL, Fedora)
?
In order to create a build directory, type
mkdir build
enter it via
cd build
and configure it:
cmake ..
After a successful configuration, you can compile it:
make
Installation is done with
make install
If a dependency such as SCIP is not found by cmake, you have to provide its
directory, by adding a -DSCIP_DIR=/path/to/scip/build/or/install argument
to the cmake call above.
In order to create all necessary links, type
make links
You can compile GCG with
make [options]
where the [options] are the same options as those from SCIP which is
documented on the official SCIP homepage under http://scip.zib.de. For further
options, consult the Makefile.
The GCG binary can be found under bin/gcg (relative to where it was built).
An elaborate example can be found in the official documentation
here.
The official documentation can be found either under http://www.or.rwth-aachen.de/gcg or it can be locally created using doxygen with
make doc
