===Install an Octave Port===
===Install an Octave Port===


MacPorts' Octave port includes the non-GPL [http://glaros.dtc.umn.edu/gkhome/views/metis METIS]. To avoid license violations do not bundle Metis with Octave and then distribute to others. In order to eliminate the Metis dependency, a local portfile may be used, and edited to remove metis.  A second motivation to use a local portfile is that the portfiles for the 3.4.x and 3.6.x series did not include all dependencies for the <code>print</code> feature.  The missing dependencies are [http://www.macports.org/ports.php?by=name&substr=epstool epstool], [http://www.macports.org/ports.php?by=name&substr=pstoedit pstoedit], and [http://www.macports.org/ports.php?by=name&substr=transfig transfig].  A third motivation for a local portfile is to provide additional flexibility in resolving problems with creating an Octave DMG using the <code>port mdmg ...</code> command.  For macports 2.1.3, having the <code>xorg-libx11</code> as a dependency for Octave has been found to cause the <code>port mdmg octave-local ...</code> command to fail.  The <code>xorg-libx11</code> dependency may be avoided by specifying <code>-x11+no_x11-docs</code> as variants and by dropping the dependence to <code>transfig</code> (which has <code>xpm</code> as a dependency and <code>xpm</code> depends upon several <code>xorg-*</code> ports.

A [[Prototype MacPorts PortFile|prototype portfile]] has been prepared, which does not depend upon METIS and does depend upon <code>epstool</code>, and <code>pstoedit</code> (there is no <code>transfig</code> dependency since it generates an <code>xorg-libx11</code> dependency). After [http://guide.macports.org/chunked/development.local-repositories.html creating a local portfile repository] an Octave portfile may be added to the local repository using the commands below.

The use of the <code>+atlas</code> variant is encouraged as bugs exist for Apple's accelerate framework in both MacOS 10.6 and 10.7.  Octave's developers have included a fix for MacOS 10.6, but the fix does not work for MacOS 10.7.  There is some commentary on this in various developers discussion forums.  For example, see [https://github.com/mxcl/homebrew/issues/6649 this Homebrew thread (Octave 3.4 fails on lion)], [https://stat.ethz.ch/pipermail/r-sig-mac/2011-September/008564.html this R-Sig-Mac thread (R 2.13.1-patched, vecLib problem on Lion)], and [http://list.coin-or.org/pipermail/ipopt/2011-October/002610.html the COIN-OR thread (Ipopt - problems on OS X 10.7 Lion)].  Use of Apple's accelerate framework should also be avoided for <code>arpack</code> and <code>qrupdate</code>.  To install the recommended variants, use the <code>port</code> commands below.

In the event errors such as the one below are encountered, the ports implicated (<code> gtk2 </code> in this case) must be clean prior to creating the dmg.

The DMG will be placed in the port's <code>work</code> directory.  If a local portfile is used, a symbolic link to the <code>work</code> directory will be placed in the directory containing the portfile.  In this instance the DMG can be found in <code>~/ports/math/octave-local/work</code>.
