1. General Users
================
A MInGW bundle is available from sourceforge.
http://octave.sourceforge.net/index.html
2. Developers
=============
The process for building Octave from source is as follows.
* Install development tools and compiler
* Install or compile dependencies of Octave
* Download Octave source
* Configure and compile source
We strongly encourage experienced users to build Octave from the
testing and development snapshots to try the latest features of Octave.
A good tutorial on building Octave for version 3.2 is available from
http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/admin/Windows/mingw32/HOWTO.txt
Additional information beyond the tutorial is summarized below.
2.1 Development tools and compiler
----------------------
Msys + MinGW development Tools
The Msys + MinGW development Tools are required to build Octave from source.
The latest version of the Msys system is 1.0.16. For MinGW, search and use
the most recent version available. Note: The Howto.txt file describing
the development tools is rather old.
The latest GCC (GNU Complier Collection) for MinGW is gcc-4.5.0. Earlier
versions are not recommended for building Octave 3.4.xx.
The latest Msys, MinGW, and GCC tools can be downloaded from
http://sourceforge.net/projects/mingw/files/
(Compiling for 64-bit binaries requires mingw-64 toolkits. This has not been
tested.)
2.2 Dependencies
----------------------
External program dependencies
* gnuplot (you can build this with the shell script mentioned in Howto.txt)
* MikTeX
* ghostscript
* pstoedit (required for printing using FLTK (OpenGL) graphics)
* fig2dev (Optional; better quality for FLTK printing in some file formats)
* sed
* less
The tools below are required for building the development sources from
the Mercurial archive, but not for simply building Octave from a snapshot
tar.gz file.
* Mercurial
* git
* automake
* autoconf
Library dependencies
Please read Howto.txt carefully on how to build them. The Howto.txt is old
so some revisions will be required when using GCC-4.5.0
2.3 Download Octave source
----------------------
The source for testing snapshots can be downloaded from the official Octave
web site. http://www.octave.org/download.html
The very latest development code is also available via anonymous access to a
read-only Mercurial archive. The method of download is described on the web
site. You will also need to install gnulib as another dependency. Please
visit http://www.gnu.org/software/gnulib/ and download sources using git.
2.4 Configure and compile source
----------------------
Building from source can be carried out using the script described in
Howto.txt.
When using GCC-4.5.0, remove flags for shared libstdc++ because a shared
build is already the default.
When running './configure', you must add '--enable-float-truncate' option.
Please see the following thread for more information:
http://thread.gmane.org/gmane.comp.gnu.octave.bugs/12361/focus=12404
To build development sources from the Mercurial repository you must run
bootstrap before running configure and make. This requires
that automake and autoconf tools be installed.
