Orocos Component Library
  ========================

Installation
============

For the minimal ocl library, do

  tar -xjvf orocos-ocl-<version>-src.tar.bz2
  cd orocos-ocl-<version>
  cmake .

If all dependencies could be found, a Makefile is generated and you
can type:

  make
  make install

If you have some of the ocl dependencies installed in non-standard
locations, you have to specify this using environment variables.  
Specify header locations using the CMAKE_INCLUDE_PATH variable.

E.g. using bash and fink in Mac OS X, the boost library headers are
installed in /sw/include, so you would specify 

export CMAKE_INCLUDE_PATH=/sw/include

before running cmake.  For libraries in non-default locations, use the
CMAKE_LIBRARY_PATH variable.

For selecting additional (hardware related) components, setting
include paths, or setting the installation prefix, do

  cd orocos-ocl-<version>
  cmake .
  ccmake .

Now a config screen appears:

  [ edit paths ]
  [ press 'c' ]
  [ check for errors, press 'e' ]
  [ select additional components ]
  [ press 'c'; check for errors, press 'e', ... ]

When all is fine, you can press 'g' in the config screen. If no 'g'
appears, the configuration is not yet correct.

Finally:

  make
  make install


Installation options
--------------------

* Orocos uses cmake (http://www.cmake.org) for its build configuration.
  CMake is a cross-platform build system. Use version 2.2 or 2.4.

* Orocos uses the 'pkg-config' program to detect installed libraries.

* This library requires that the Orocos RTT (liborocos-rtt) is installed
  (path in OROCOS_INSTALL) Some components require the Orocos KDL (path in KDL_INSTALL)
  or the Orocos BFL (path in BFL_INSTALL).

* You can set the installation prefix in the CMAKE_INSTALL_PREFIX variable
  using ccmake.

* You can additionally

  1) do out-of-source builds:

	$ mkdir build
	$ cd build
	$ cmake ..
	$ make

  2) set a different compiler:

	$ CC="distcc gcc-3.3" CXX="distcc g++-3.3" cmake ..

     or use the 'configure' wrapper script:

	$ ../configure CC="distcc gcc-3.3" CXX="distcc g++-3.3"

  3) use the GUI Configurator:

	Use 'ccmake' rather than 'cmake' for a text-based configurator.

  4) have packaging support:

	$ make install DESTDIR=/staging/dir
