:Octave Forge packages have each a cygwin package.
:Its announce on cygwin mailing list [https://cygwin.com/ml/cygwin-announce/2017-01/msg00078.html]
: Full cygwin package list is available here [https://cygwin.com/packages/]
: At 2017-04-06, 64 forge packages were available.
*To install :
: run cygwin setup-x86.exe (for cygwin 32 bit) or setup-x86_64.exe (for cygwin 64 bit) and select them in the Math category.
: All the package dependencies will be also installed.
:Graphics is based on X and to plot you will need to start octave within xterm (or similar).
: I recommend to install "xinit", "xlaunch" and "gnuplot". These packages will pull all the functional Xserver.
: Otherwise the only graphics will be ASCII art ;-)
==Notes for 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
* To build GNU Octave from cygwin source package, you need to install "cygport" and the relevant development libraries
tar -xf octave-4.4.1-1-src.tar.xz
cygport octave.cygport almostall
:see [https://cygwinports.github.io/cygport/ cygport documentation] for further info.
Be advised that GNU Octave is primarily developed on GNU/Linux and other [https://en.wikipedia.org/wiki/POSIX POSIX] conform systems. The ports of GNU Octave to Microsoft Windows use different approaches to get most of the original Octave and adapt it to Microsoft Windows idiosyncrasies (e.g. 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. GNU Octave standalone ports for Windows are independently compiled using either the [http://mingw.org MinGW] or Microsoft Visual Studio development environments (3.6 or before).
