Getting the IPOPT code via subversion

Of course, the subversion client must be installed on your system if you want to obtain the code this way (the executable is called svn); it is already installed by default for many recent Linux distributions. Information about subversion and how to download it can be found at http://subversion.tigris.org/.

To obtain the IPOPT source code via subversion, change into the directory in which you want to create a subdirectory Ipopt with the IPOPT source code. Then follow the steps below:

1. Download the code from the repository
   $ svn co https://projects.coin-or.org/svn/Ipopt/stable/3.5 CoinIpopt
   Note: The $ indicates the command line prompt, do not type $, only the text following it.
2. Change into the root directory of the IPOPT distribution
   $ cd CoinIpopt

In the following, ``$IPOPTDIR'' will refer to the directory in which you are right now (output of pwd).
