Also, we don't currently provide 64-bit GRASS binaries for Windows, so you'd need to build it from source with a compiler that can produce 64-bit executables (and you'll need 64-bit versions of all of the relevant libraries). The last time I checked, MingGW-64 was still quite unstable, although I don't know if that has changed since. The build system doesn't support compiling with MSVC (and the free edition doesn't support building 64-bit binaries). -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
