[Gstat-info] gstat 2.5.1 on Linux

[Andrew Becker]

Hi - I am trying to use this package on Linux (RHEL).  I have untarred the source package and am 
able to build the library and executables.  If I go to the cmd/ directory and run

   ../bin/gstat ex01.cmd

things seem to work OK.  However, once I have to start reading the file "cmd/mask_map", e.g.

   ../bin/gstat ex03.cmd

I get errors like

  gstat: Linux version 2.5.1 (02 April 2007)

  Warning: converted null-character(s) in `mask_map' to space
  gstat: read failed on file `mask_map'

The file "cmd/mask_map" seems like a file of invalid characters (white question marks inside black 
circles; I've never seen that ASCII character before!).  Same with "part_a", "part_b", and 
"sqrtdist".  All the ".eas" files seem to be correctly formatted.

I have searched for these files on-line, and downloaded previous versions of gstat, all to no avail. 
  Is there a way to generate these files, or another location on-line where I can download them?

Thanks,
Andy
