TO INSTALL RUN: perl Makefile.PL make make test make install For this module to install and work you will need to have statvfs() on your system. A good way to tell if it is there is to look for sys/statvfs.h in your include directory. (Usually /usr/include/) If there is an error during the 'make' it is possible that you do not have statvfs() on your system. Another reason may be that the statvfs structure defined in statvfs.h does not contain one or more of the fields that are defined in Filesys.xs. During the 'make test' test.pl will use statvfs() to stat the root directory "/". If it fails it will report the error, otherwise it will report all the standard fields in the statvfs structure. In the future I plan on having support for statfs() and to to have all fields available for statvfs() depending on the OS. For instance HP-UX has two extra non standard fields in their statvfs structure. Once installed run 'perldoc Filesys::Statvfs' and 'perldoc Filesys::Df' for more information. If you have any problems or questions please email me at IGuthrie@aol.com with "Filesys Module" in the subject line.
