Build & Install

The section describes how to build and install the BGL-Python bindings.

Installing Prebuilt binaries

Prebuild binaries might already be available for your
platform on the BGL-Python web site at:

  http://www.osl.iu.edu/~dgregor/bgl-python/

To install pre-built binaries, use:

  python setup.py install

By default, the BGL-Python bindings will be installed into the
appropriate Python site-packages directory (e.g.,
/usr/lib/python2.3/site-packages). However, there are several
alternative installation options that one can pass on the command
line:

  --home=DIR          This option will install the BGL-Python module
                      into the home directory DIR, with the Python
                      module stored in DIR/lib/python and supporting
                      shared libraries stored in DIR/lib. Be sure that
                      DIR/lib/python is in your PYTHONPATH and DIR/lib
                      is in your dynamic linker's path (e.g.,
                      LD_LIBRARY_PATH or DYLD_LIBRARY_PATH).

  --exec-prefix=DIR   This option will change the executable prefix used
                      to install BGL-Python as a site-wide
                      package. The BGL-Python module will be placed in
                      DIR/lib/pythonVERSION/site-packages and the
                      supporting libraries will be placed in DIR/lib.

  --pythonlibdir=DIR  This option will force the installer to place
                      the BGL-Python module in DIR.

  --libdir=DIR        This option will force the installer to place
                      the BGL-Python supporting libraries in DIR.


Prerequisites
~~~~~~~~~~~~~

  - A very modern C++ compiler. We have tested with GNU C++ versions
    3.3 and newer and Microsoft Visual C++ 7.1 and newer. 

  - Boost 1.34.0 or newer: At present, Boost 1.34.0 is only available
    via Boost CVS. See http://www.boost.org for information about
    retrieving Boost from CVS. Note: You must have a complete Boost
    distribution available (e.g., retrieved via CVS or as part of a
    Boost tarball) to compile the BGL-Python: the BGL-Python bindings
    will not compile properly with already-installed Boost trees.

  - Python 2.2 or newer. Be sure that the Python headers are
    installed!

We will assume that the Boost distribution is in a directory we refer
to a BOOST_ROOT. 


Boost.Jam
~~~~~~~~~

We use the Boost.Build system to build the Python bindings for the
BGL. The "Preparation" section at the following web page describes
how to build Boost.Jam, which is the core of the build system:

  http://www.boost.org/more/getting_started.html#Preparation

However, most users can just enter the directory 

  $BOOST_ROOT/tools/jam/src

and run either build.sh (for Unix-like systems) or build.bat (for
Windows). Copy the "bjam" executable from this step some place
convenient: we'll be using it to build the Python bindings.


Python Configuration
~~~~~~~~~~~~~~~~~~~~

The BGL-Python bindings use the excellent Boost.Python library to
reflect the C++ data structures and algorithms into Python. Although
we build the Boost.Python library automatically, you may still need
to follow the configuration advice here:

  http://www.boost.org/libs/python/doc/building.html

Most likely, you will only need to add the following to your
user-config.jam:

  using python : 2.3 ;

Replace "2.3" with the major and minor version of Python you have,
e.g., 2.2., 2.3, 2.4, or 2.5.


Build & Install
~~~~~~~~~~~~~~~

Once you have determined which Boost.Jam options you will need, change
to the top-level BGL-Python directory and run bjam:

   bjam <options> install

By default, the BGL-Python bindings will be installed into the
appropriate Python site-packages directory (e.g.,
/usr/lib/python2.3/site-packages). However, the same installation
options are available here as for the setup.py script in the pre-built
binaries:

  --home=DIR          This option will install the BGL-Python module
                      into the home directory DIR, with the Python
                      module stored in DIR/lib/python and supporting
                      shared libraries stored in DIR/lib. Be sure that
                      DIR/lib/python is in your PYTHONPATH and DIR/lib
                      is in your dynamic linker's path (e.g.,
                      LD_LIBRARY_PATH or DYLD_LIBRARY_PATH).

  --exec-prefix=DIR   This option will change the executable prefix used
                      to install BGL-Python as a site-wide
                      package. The BGL-Python module will be placed in
                      DIR/lib/pythonVERSION/site-packages and the
                      supporting libraries will be placed in DIR/lib.

  --pythonlibdir=DIR  This option will force the installer to place
                      the BGL-Python module in DIR.

  --libdir=DIR        This option will force the installer to place
                      the BGL-Python supporting libraries in DIR.

Getting Help
------------

The Python interface to the BGL contains extensive on-line help. Use
the help() command in Python or pydoc to view help for any of the
components or algorithms of the BGL. If you are still having trouble,
feel free to contact us via the Boost-Users or Boost mailing lists at:

    Improvements include:
      - Vertex/edge properties are available as attributes in vertex
        and edge objects
      - Vertex/edge objects now have stable addresses, so they can be
        used as keys in Python dicts.
      - Property maps now perform automatic conversions to the
        appropriate underlying type.
      - More BGL algorithms are available in Python
      - Added GraphML input/output
      - Pickling/unpickling of BGL graphs now works properly
 
  - November 23, 2005 - Version 0.9 of BGL-Python bindings.  The
    initial release as a separate package.
