INSTALLATION
============
This document gives a basic overview of the installation procedure. For full
installation instructions, please see:
http://openbabel.org/docs/dev/Installation/install.html
Requirements
============
-- CMake 2.4.8 or later
-- Eigen 2.0.3 or later (optional)
-- libxml2 (optional)
-- zlib (optional)
-- wxWidgets 2.8 (optional, needed to build GUI)
Basic Installation
==================
These instructions give a very basic overview of how to configure, compile and
install Open Babel on most systems. If you are using unique install locations
and/or libraries are not automatically detected please consult the 'Advanced'
section.
The following instructions assume that the Open Babel source distribution is in
the directory ~/openbabel-2.3.0.
1. Create a 'build' directory:
mkdir build
cd build
2. Configure the build system. You can specify additional build
options at this time (see below):
cmake ~/openbabel-2.3.0
3. Compile:
make -j2
4. Test (optional):
make test
5. Install:
sudo make install
Advanced
========
The build system (CMake) provides mechanisms for specifying
non-standard installation locations and enabling/disabling of optional
components.
-DCMAKE_INSTALL_PREFIX : specify the installation prefix
(default /usr/local)
-DLIB_INSTALL_DIR : specify the install location for libraries
(default ${CMAKE_INSTALL_PREFIX}/lib)
-DEIGEN2_INCLUDE_DIR : specify the Eigen include directory
-DRUN_SWIG : specify whether to regenerate language bindings
-DPYTHON_BINDINGS : specify whether to build Python bindings
-DMINIMAL_BUILD : specify whether to do minimal build with just two
formats (SMI, SDF) useful for developers
-DBUILD_GUI : specify wether to build Open Babel GUI (wxWidgets required)
For more information please consult the CMake documentation and the
Open Babel website:
http://openbabel.org/docs/dev/Installation/install.html
Environment Variables
==================
Open Babel uses a few environment variables to find things at
runtime. If Open Babel is installed to the location specified at
compile time, none of these variables need to be set.
BABEL_LIBDIR - the location of Open Babel format plugins
BABEL_DATADIR - the location of the data files
