ADOL-C

This new version of ADOL-C features new library functions for

- sparse Jacobians and sparse Hessians
- external differentiated functions
- optimal checkpointing
- adapted differentiation of fixed point iterations
- parallel differentiation of OpenMP-parallel loops
- Lie derivatives of scalar, vector and covector fields

and many bug fixes.

Furthermore the source code was adapted to allow a compilation with
WINDOWS compilers. See file "INSTALL" for generic installation
instructions and special instructions for the installation on a WINDOWS
platform.

The complete documentation can be found in the subdirectory "doc".


Local installation using CMake
==============================

1. Create a build directory somewhere, and move into that directory

2. Call CMake:

cmake -DCMAKE_INSTALL_PREFIX=/path/you/want/to/install/in path/to/adolc/sources

3. Build and install:

make
make install


Local installation using the AutoTools
======================================

1. Type autoreconf -fi

2. Run configure with possibly using one of these options:

--prefix=PREFIX install library and header files in PREFIX
(default: ${HOME}/adolc_base)

--enable-sparse build sparse drivers [default=no]

--with-openmp-flag=FLAG use FLAG to enable OpenMP at compile time
[default=none]

--enable-docexa build documented examples [default=no]
--enable-addexa build additional examples [default=no]
--enable-parexa build parallel example [default=no], if yes
-with-openmp-flag=FLAG required

--with-cflags=FLAGS use CFLAGS=FLAGS (default: -g -O2)
--with-cxxflags=FLAGS use CXXFLAGS=FLAGS (default: -g -02 -std=c++11)

--with-boost=BOOST_PATH path to the compiled boost library, otherwise
the system one is chosen by default (if exists)

3. Type make

4. Type make install

By default, `make install' will install all the files in ${PREFIX}/lib and
${PREFIX}/include. You can specify another installation directory by using
the --prefix-option in the configure call.

This procedure provides all makefiles required in the appropriate directories.
Execute 'configure --help' for more details on other available option.



Nonlocal installation
=====================

As mentioned in INSTALL one can configure the adolc package to be installed
in a different directory than "${HOME}/adolc_base" by using the "--prefix=PATH"
configure option. This is typically used for global installations. Common PATHs
are "/usr" and "/usr/local/", and others are known to be used. Fine control
over the installation directories can be gained by supplying additional
configure options. See "./configure --help" for details.

Completing the installation by executing "make install" requires write
permissions for all target directories. Make sure to have them or the result
may be surprising otherwise.

A global installation can be helpfull if many users need the library. By adding
the library's path to "/etc/ld.so.conf" the usage of LD_LIBRARY_PATH and the
"-L" link switch becomes unnecessary. In many cases, for instance for
PATH=/usr/local, the use of the -I directive for compiling sources becomes
unnecessary too.



Examples
========

Examples must be configured to build by using the configure switches
--enable-docexa or --enable-addexa.
They will never be installed by make install but can be found in the
appropriate example subdirectory.


Windows Compilation with MINGW
==============================

Please refer to INSTALL

Windows Compilation with Visual Studio
======================================

Please refer to the file windows/Readme_VC++.txt for building the library and
ADOL-C/examples/Readme_VC++.txt for the documented examples.



Unit tests
==========

ADOL-C provides more than 400 unit tests to verify its basic functionality.
For more information how to run the tests, please check the README file in ADOL-C/boost-test directory.

Enjoy this new version!
