Starting with version 3.0.1, Octave is once again part of the normal net distribution of Cygwin, available from http://www.cygwin.com. It is possible to build Octave from source on Windows systems with Cygwin, but with the old gcc-3.4.4-3 compiler there are some performance problems related to the way C++ exception handling is implemented. This is a known problem with a long history and it is STRONGLY encouraged to use gcc-4.3.2-1 or later. Current binary versions are built with gcc-4.5.3-3. ------- SUGGESTED CONFIGURATION --------------------------- The latest development Octave development sources (octave-3.5.91+) are built with: configure --enable-shared \ --enable-float-truncate \ CC=gcc-4 F77=gfortran-4 CXX=g++-4 CPP=cpp-4 lt_cv_deplibs_check_method=pass_all \ LDFLAGS=-Wl,-no-undefined "--enable-float-truncate" is needed for the following bug: http://thread.gmane.org/gmane.comp.gnu.octave.bugs/12361/focus=12404 Without it, one of the quadgk test will fail as "a=a" could be false due to truncation problems with complex numbers. "lt_cv_deplibs_check_method=pass_all" is needed to bypass incorrect libtool detection of system capabilities and to allow shared libs building. "LDFLAGS=-Wl,-no-undefined" is better than previous "LDFLAGS=-no-undefined" as gcc-4 is now complaining about unknown command and the "undefined" is for the linker. The additional patch used for 3.4.3-3 package can also be needed for 3.6.x (see below). ------- SUGGESTION FOR FORK ISSUE -------------------------- The build process can fails in building images for documentation due to fork issue of the octave dll just built. In such case I suggest to rebase the built dll's with: $ find build_tree -name "*.dll" > rebase_list and after closing all cygwin process, from a dash shell $ rebaseall -s 'dll|so|oct' -T /full_path/rebase_list After rebasing the "make" should be able to complete the creation of the images and the documentation. ------------------------------------------------------ Octave-3.4.3-3 package was built using: configure --libexecdir=/usr/lib \ --enable-shared \ --enable-float-truncate \ F77=gfortran-4 \ lt_cv_deplibs_check_method=pass_all \ LDFLAGS=-no-undefined plus and additional patch to solve a specific cygwin fltk print issue, see: https://savannah.gnu.org/bugs/?31641 Octave-3.2.4 was built using: configure --enable-shared \ --without-fltk \ --without-framework-opengl \ CC=gcc-4 F77=gfortran-4 CXX=g++-4 CPP=cpp-4 CFLAGS="-Dtimezone=_timezone" ------------------------------------------------------ Current Cygwin package maintainer for Octave: Marco Atzeri http://matzeri.altervista.org Marco Atzeri marco.atzeri@gmail.com Italy Last updated: Tue Jan 3 14:40:58 WEST 2012
