[Met_help] error building MET with cygwin/gcc

Mike,

Since you've built MET as 64-bit, I don't think you'll be able to run PB2NC because BUFRLIB won't work well.

If you had built MET as 32-bit, you could run PB2NC but you'd likely need to "reblock" the sample PREPBUFR data in the MET tarball using the "cwordsh" FORTRAN blocking utility.  That step is mentioned 
in the MET tutorial here: http://www.dtcenter.org/met/users/support/online_tutorial/pb2nc/index.php

Or from the top-level METv1.1 directory in a C-Shell, this foreach loop would reblock the data:

foreach file (`ls data/sample_obs/prepbufr/* | cut -d' ' -f9`)
/path/to/cwordsh unblk ${file} ~/tmp.unblk
/path/to/cwordsh block ~/tmp.unblk ${file}
end
rm ~/tmp.unblk

Where /path/to/cwordsh is the path to your version of the cwordsh tool.

We're considering alternatives to using BUFRLIB since it's been causing the majority of the issues people are encountering in using MET.

Hope that helps.

John
