Octave has been mostly ported to Windows NT and Windows 95 using the
beta 17 release of the Cygnus GNU-WIN32 tools.  Not everything works,
but it is usable.  If you would like to volunteer to work on
improving this port, please contact

Here is a list of current problems (and workarounds, where available).

* There is no binary version of Octave available for Windows NT or
  Windows 95.  One will probably be released when the port is a little
  more stable.

* To compile and install Octave on a Windows NT or Windows 95 system,
  you will need to get the beta 17 release of the GNU-WIN32 tools.  They
  are available from

* There is a conflict between the files /cygnus/include/g++/String.h and
  /cygnus/H-i386-cygwin32/i386-cygwin32/include/stringh.  You should
  rename or remove /cygnus/include/g++/String.h.  (These file names
  assume that you have installed the GNU-WIN32 tools in /cygnus).

* On Windows 95 systems, there is a bug that causes redirections to
  /dev/null to fail.  You can work around the problem by substituting
  /dev/nul for /dev/null in all of the files that use it.  (This
  problem is fixed in the b17.1 release of the tools.)

* You will need to have f2c and libf2c.a or g77 installed.  You can get
  a copy of f2c from

* You will also need a termcap library.  The GNU termcap library seems
  to work.  You can get it from any GNU archive site, including

* GNU info doesn't work yet.  It compiles but doesn't run.  Perhaps the
  problem is just that a proper termcap entry needs to be defined.

* If no other pager can be found, Octave will use  Since
  that's a pretty limited pager (no going backward, etc.) you may want
  to find a working version of less.  The GNU-WIN32 tools used to
  include a copy of less, but I am told it was dropped from the
  distribution because it didn't work very well.  If you know of a
  better port of less that will work with Octave, please contact

* To make plotting work, you will need to find a version of gnuplot
  that can read commands from a pipe.  The binary versions of gnuplot
  for Windows that I found could only read from their command windows,
  and wouldn't accept commands through a pipe, so they could not be
  called from Octave.

  After deleting -DREADLINE from the Makefile, I was able to compile a
  working version of gnuplot 3.6 beta 315 using the GNU-WIN32 tools,
  but it does not support the Windows graphics terminal.  It does
  support dumb terminals and lots of other output devices, including
  PostScript, but it would be much nicer if it could open a separate
  window and draw pretty graphs there.

If you know of solutions for any of these problems, please contact
