Overhaul FLTK plotting and printing
* gl2ps-renderer.cc: Force execution of GL commands before gl2psEndPage to
avoid missing primitives in output. Enable error output of gl2ps,
check return value of gl2psBeginPage for error.
* __init_fltk__.cc:
Avoid redraw of the OpenGL and the plot window if not needed.
Let FLTK do the resizing of the canvas, the menubar and the statusbar.
This was done by creating a resize_dummy and set this as resizable
for the plot_window group. Previously this was done inside draw().
Avoid timing issues with fltk_maxtime (removed) and other hacks with
multiple Fl::check and redraw () calls. You can use flush and glFlush
if you really need to force a immediate redraw.
Remove print_mode in draw () and print directly without waiting that
FLTK flushes its buffers. This fixes bug #42458 and #40215
Manually placement of the toolbar is only done once when hiding or
showing the menubar. (update_toolbar_position)
set(gcf, "position", [x, y, w, h]) is now handled by
figure::properties::ID_POSITION which calls update_position
* __add_default_menu__.m: Remove now unneeded hacks for the menubar.

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. Tatsuro MATSUOKA tmacchant@yahoo.co.jp Benjamin Lindner bjmldn@gmail.com Last updated: Sat Jan 22 17:29:12 PST 2011
