GNU Octave is primarily developed on GNU/Linux and other POSIX conformal systems. The ports of GNU Octave to Windows use different approaches to get most of the original Octave and adapt it to Microsoft Windows idiosyncrasies (eg: dynamic libraries, file paths, permissions, environment variables, GUI system, etc). Bear this in mind and don't panic if you get unexpected results. There are a lot of suggestions on the mailing lists for tuning your Octave installation.

About version numbers (March 2011):

  • The 3.4.x are current releases.
  • The 3.2.x are previous releases.

Notes

  • Although there are some remaining known issues, some bugs reported to the octave-3.2.3 have been corrected. In addition, useful octave-forge packages are added (Java, Jhandles, ....). Please see RELEASE_NOTES.txt for details:
  • Default Octave install folder changed to e.g. C:\Octave\3.2.4_gcc-4.4.0\.
    If you have installed octave in a folder where the path name has whitespace, for example, C:\Program Files\, 'pkg install (package name)' command will fail: See http://sourceforge.net/mailarchive/message.php?msg_name=4A1AF9EF.1000005@hotmail.com for details

Additional important topics found after the release: 

     pkg rebuild -noauto oct2mat
at the octave prompt and then restart octave. The operation results in the oct2mat package not to be auto-loaded in startup. When you want to use oct2mat, execute
     pkg load oct2mat
  • The plot octave-forge package still have ginput code although the ginput function is now merge into octave itself. Therefore conflict occur if the plot package is installed. To avoid this problem, rename 'ginput.m' in the folder ..\Octave\3.2.4_gcc-4.4.0\share\octave\packages\plot-1.0.7, for example ginput.ob.m. In some computers which has one core CPU, response of ginput is very slow. In the case, modify '__gnuplot_ginput__.m' according to the following thread. http://old.nabble.com/ginput-on-Octave-3.2.4-mingw32-to28093888.html
  • From gnuplot-4.4.0, the default terminal of gnuplot for windows is the wxt terminal. Some users may set the GNUTERM environmental variable for the windows terminal being default. The gnuplot for windows allows to set GNUTERM to 'win' (abbreviated form) but octave does not recognize the abbreviated form for terminal name. If one would like set GNUTERM to windows terminal, one should specify it as 'windows' (full form) but not 'win' (abbreviated form). In detail see the following thread: http://old.nabble.com/flicking-problem-again-Octave-3.2.4-mingw32-td28038688.html

Octave on Cygwin

Octave 3.4.2 on cygwin

  • octave 3.4.2-3
  • octave-forge packages octave-forge-20110730-1
  • Please select them in Math category in the cygwin setup (using setup.exe).
    On Cygwin 1.7.9-1 the communication between octave and gnuplot is broken due to a cygwin bug. Please use a cygwin snapshot or 1.7.8-1 until cygwin-1.7.10-1 is released. Cygwin 1.7.8-1 is reported to currently work, but snapshots have notable performance improvements, so they are recommended. While the communication with gnuplot does not work, a different graphic toolkit may be available: at the Octave prompt, type available_graphics_toolkit, and then try setting a different toolkit, for instance graphics_toolkit('fltk') before testing with the sombrero command.

Notes

   bunzip2 cygwin1-20111020.dll.bz2
   cp cygwin1-20111020.dll cygwin1.dll
   cp /bin/cygwin1.dll /bin/cygwin1.dll_backup
    • exit all cygwin processes and from windows explorer
    • copy the cygwin1.dll snapshot to
   c:\cygwin\bin 
   (or in the equivalent directory of your cygwin installation).
  • Graphics is based on X, so to plot you need to start octave within xterm (or similar).
  • A new fltk graphics_toolkit is available, and the crash on "print" issue was solved on 3.4.2-3 using the patch proposed here: https://savannah.gnu.org/bugs/index.php?31641
  • If a dlls collision arise, the correct invocation of the rebase utility within dash shell is:
   rebaseall -s "dll|so|oct"
as octave dll's use unexpected ".oct" suffix for its own extension.
  • For general build notes, see etc/README.Cygwin.
  • When building from development source (default branch)
   "make check"
passes almost all the tests.
Only, and not substantial, failures are:
   /pub/hg/octave/src/data.cc : 8 failures due to different handling of complex Inf on sort
   /pub/hg/octave/src/syscalls.cc: 1 failure on fork. This disappears when octave is installed
   /pub/hg/octave/scripts/sparse/svds.m: 1 failure due to test sensitivity on starting point. See 
   https://mailman.cae.wisc.edu/pipermail/octave-maintainers/2011-September/024715.html
  • To build from cygwin source package, you need to install "cygport" and the relevant development libraries
   $ tar -xvjf octave-3.4.2-3-src.tar.bz2 
   gl2ps-print.patch 
   octave-3.4.2-3.cygport 
   octave-3.4.2-3.cygwin.patch 
   octave-3.4.2-3.src.patch 
   octave-3.4.2.tar.bz2

   $ cygport octave-3.4.2-3.cygport almostall
see cygport documentation for further info.
