Hi, Recently, the MinGW packages for 32-bit and 64-bit have entered Cygwin. This will facilitate the life of Windows users and developers of Dynare in two ways: - the compilation of Dynare under Windows can now be entirely done under Cygwin, without the need to download an external compiler; the Windows section on the wiki page has been correspondingly updated: http://www.dynare.org/DynareWiki/BuildingDynareFromSource - the "use_dll" option also benefits from this change, and in particular it is possible to use GCC under 64-bit MATLAB with this option. An updated "mexopts.bat" file, using the new MinGW packages, is available on the following page: http://www.dynare.org/DynareWiki/ConfigureMatlabWindowsForMexCompilation Best, -- Sébastien Villemot CEPREMAP — http://www.cepremap.ens.fr Dynare project — http://www.dynare.org Phone: +33 1 40 77 49 90 PGP Key: 0xA6C029B9D06B2913D71C105EBE37E801FB6EFF8B (http://pgp.mit.edu/)
