Speaking for the mingw-build, there are in principal two options: 1) native mingw64 build 2) cross-building on a win32 system To try 1) I guess you would require to have all of your building environment as native win64 version. Don't know if this is avilable. ad 2): I have no experience in doing cross-building, so I don't know what one would exactly require in which (32 or 64 bit) version. Side note: ATLAS currently is built using cygwin and cygwin-gcc. So for 64bit ATLAS you will also need at least a 64bit-target cygwin gcc. Don't know about how well cross-compiling ATLAS works. > I had a quick look at the scripts in: > > octave-forge/svn/octave/trunk/octave-forge/admin/Windows/ > > for mingw32 and msvc to see if they could be adapted to use > > http://sourceforge.net/projects/mingw-w64/ > > or MSVC 2008 (express) for 64-bit WIndows. What is needed to do this? Well, it depends on *how* the mingw64 build is to be accomplished :) I had a look at the mingw-w64 project homepage. The have gcc-4.4.0 snapshots, so not a stable gcc release yet, and no useful package release (mingwrt, win64api, binutils) yet. So this is highly experimental at the moment. benjamin ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Octave-dev mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/octave-dev
