These are quick install instructions mainly intended for UNIX-like systems
(including Linux, OS X, AIX, Cygwin and MSys). Additional details for building
this and other COIN projects are available at

You can find instructions for building with Microsoft Visual Studio under
Windows at

***                         DOWNLOAD                               ***
**********************************************************************

Pre-built binaries are available for some versions of Cbc on some platforms.
They can be downloaded at

  http://www.coin-or.org/download/binary/Cbc

If you would like to build from source, you can obtain the source code for the
Cbc package in two ways:

1. Obtain the source directly from the COIN-OR subversion repository
   (recommended). For this you needs the program 'svn' installed on your
   machine, and output of "svn --version" must contain "handles 'https'
   scheme". On Windows, it is recommended to get the source with the SVN
   client TortoiseSVN (http://tortoisesvn.net).

   Assuming that you want to download a release version 2.7.0, as an example,
   you would execute the command

   svn co https://projects.coin-or.org/svn/Cbc/releases/2.7.0 Cbc-2.7.0

   You can similarly get source for the latest stable version or the trunk
   (development) version.

2. Download the tarball from http://www.coin-or.org/download/source/Cbc 
   and extract it. For example, for the release 2.7.0 you type

   gunzip Cbc-2.7.0.tgz
   tar xvf Cbc-2.7.0.tar

**********************************************************************
***                        CONFIGURATION                           ***
**********************************************************************

Go into the directory that you just downloaded or extracted (e.g., Cbc-2.7.0).
Then create a build directory and configure the package by typing

   mkdir build
   cd build
   ../configure

Note that you might have to specify additional options, in case you
don't want to use the default choices that configure makes (e.g.,
compilers).  Please visit

   https://projects.coin-or.org/BuildTools/

and the Cbc Trac page

   https://projects.coin-or.org/Cbc

for more information.

If everything went fine, you will see at the end of the output

   "Main configuration of Cbc successful"

**********************************************************************
***                COMPILATION AND INSTALLATION                    ***
**********************************************************************

In the directory where you ran the configure script:

1. Compile the code by typing

   make

2. To test if the code works, you can type

   make test

3. To install the code, you type

   make install

   After this, you will find the executables, libraries and header
   files in the "bin", "lib" and "include" subdirectory, respectively.

More information on the compilation and installation can be found at

   https://projects.coin-or.org/BuildTools/

**********************************************************************
***                     USING CBC                                  ***
**********************************************************************

After installing Cbc, you will have an executable named "cbc" (Unix-like
environments) or "cbc.exe" (Windows). We will call it "cbc" from here on.

The executable "cbc" takes various options. First, run the program in
interactive mode by typing just "cbc" on the command line with no arguments.
You will see the prompt

CoinSolver takes input from arguments ( - switches to stdin)
Enter ? for list of commands or help
Coin:

Type ? to get some idea of what you can do. The executable can also be run in
batch mode. To simply solve a given instance with default parameter settings, type 

cbc <file> 

By typing a sequence of interactive commands on the command line
with each command preceded by a "-", you can run set parameters and chane other options. For example, typing

cbc <file> -cuts root -solve 

will import file and solve the problem, generating cuts only at the root node.
On Linux, the cbc interactive solver can do file completion and line editing
if built from source with that option enabled.

With the installed libraries, you can also link your own code with the
installed libraries. You can find examples in the

   Cbc/examples/

To build these examples, go into the directory build/Cbc/examples and type

   make sample1

to build the executable corresponding to sample1.cpp. The two simplest samples
are:

sample.cpp  This is a simple program to read an mps file.and solve the
		integer problem.

sample2.cpp.  This is the benchmark driver for the competition.  It overrides
		the default branching methods and adds a (mildly useless)
		heuristic.  It is intended to show you how to add your
		own methods.  See CbcCompareUser.hpp for how to modify
		choice of node from tree.  See CbcBranchUser.?pp for
		how to modify which variable is chosen at a node.  For
		more complex stuff such as new types of branches see
		CbcBranchBase and CbcBranchActual in directory Cbc.
		To see how to add heuristics see CbcHeuristicUser.?pp.

		To add cut generators - define them as in Cgl and then just
		add them as in sample2.cpp

		The script "runtimes" in Samples directory will
		run some or all of test set.  The version checked in
		does some - just take off # to run.  An optional time
		in minutes can be passed.
