Compiling GRASS natively on MS-Windows/MinGW: see Instructions.

Notes

• While generally it is not a problem, GRASS GIS does not cope well (yet) with spaces in directory and file names in all cases. Take this into account when installing GRASS on MS-Windows if you are experiencing problems.
• When selecting the root install directory, make sure that the 'Default Text File Type' is set to Unix.
• You must install/compile GRASS on a NTFS partition (FAT will not work!).
