Purpose
CppAD is an include file library and you therefore need the source code to use it. This section discusses how to download the different versions of CppAD.

Distribution Directory
We refer to the CppAD source directory created by the download instructions below as the distribution directory. To be specific, the distribution directory contains the file cppad/cppad.hpp.

Version
A CppAD version number has the following fields: yyyy is four decimal digits denoting a year, mm is two decimal digits denoting a month, and dd is two decimal digits denoting a day. For example version = 20160101 corresponds to January 1, 2016.

Release
Special versions corresponding to the beginning of each year have mm and dd equal to zero. These version numbers are combined with release numbers denoted by rel . Higher release numbers correspond to more bug fixes. For example version.rel = 20160000.0 corresponds to the first release of the version for 2016, 20160000.1 corresponds to the first bug fix for 2016.

License
We use lic to denote the licence corresponding to an archived version of CppAD. The GNU General Public License is denoted by lic = gpl and the Eclipse Public License is denoted by lic = epl .

Compressed Archives
The Coin compressed archives have the documentation built into them. If you downloading an old version using another method; see building documentation .

Coin
The compressed archive names on the Coin download page have one of the following formats:



     cppad-version.rel.lic.tgz

     cppad-version.lic.tgz

In Unix, you can extract these compressed archives using tar. For example,



     tar -xzf cppad-version.rel.lic.tgz

No matter what the format of the name, the corresponding distribution directory is cppad-version . To see that the extraction has been done correctly, check for the following file:



     cppad-version/cppad/cppad.hpp

Github
The compressed archive names on the Github download page have the format



     cppad-version.rel.tgz

These archives correspond to the Eclipse Public License.

Source Code Control
These methods only provide the Eclipse Public License version of CppAD.

Git
CppAD source code development is current done using git You can a git clone of the current version using the command



    git clone https://github.com/coin-or/CppAD.git cppad.git

This procedure requires that the git is installed on your system.

Subversion
A subversion copy of the source code is kept on the Coin web site. You can obtain this subversion copy using the command



     svn checkout https://projects.coin-or.org/svn/CppAD/trunk cppad.svn/trunk

This procedure requires that the subversion program is installed on your system.

Monthly Versions
Monthly versions of the compressed tar files are available on the Coin download page . These are kept until the end of the current year, when the next release is created. The monthly versions have the form



     cppad-yyyy0101.lic.tgz

Windows File Extraction and Testing
If you know how to extract the distribution directory from the tar file, just do so. Otherwise, below is one way you can do it. (Note that if 7z.exe, cmake.exe, and nmake.exe are you your execution path, you will not need to specify their paths below.)

Download and install the open source program http://www.7-zip.org .
Download and install the Visual Studio Express; for example Visual Studio 2013
In a command window, execute the following commands: set PATH=path_to_7_zip;%PATH% set PATH=path_to_cmake;%PATH% set VCDIR=path_to_vcdir;%PATH% call "%VCDIR%\vcvarsall.bat" x86 For example, on one machine these paths had the following values: path_to_7_zip=C:\Program Files\7-zip path_to_cmake=C:\Program Files (x86)\CMake\bin path_to_vcdir=C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC
Use the following commands to extract the distribution from the compressed archive: 7z x cppad-version.lic.tgz 7z x cppad-version.lic.tar
To see if this has been done correctly, check for the following file: cppad-version\cppad\cppad.hpp
The commands below are optional. They run the CppAD tests using the default cmake settings (except for the generator option) mkdir build cd build cmake -G "NMake Makefiles" .. nmake check

Install Instructions
The install instructions on this web site correspond to the current version of CppAD. If you are using an old version of CppAD these instructions may work. If you have trouble (or just to be careful), you should follow the instructions in the doc subdirectory of the distribution directory. If there is no such documentation, you can build it; see building documentation .

Building Documentation
If you are using one of these download methods, you can build the documentation to get the corresponding install instructions. The documentation for CppAD is built from the source code files using OMhelp . You will need to install the omhelp command so that

 
     which omhelp

shows it is in your path. Once you have done this, in the distribution directory execute the following command:



     bin/run_omhelp.sh htm

You will then be able to follow the install instructions in the doc subdirectory of the distribution directory.
