wgrib2.tgz vs wgrib2_nolib.tgz

                     wgrib2.tgz: built-in libraries

The easy way to compile wgrib2 is to download the wgrib2.tgz.(VERSION) 
file.  The tarball contains all libraries you need in order to compile
wgrib2 (except for the optional netcdf4 and mysql).  The makefile will compile 
all the libraries to create the wgrib2 executable.  This is the easy way of 
installing wgrib2.  

                     wgrib2_nolib.tgz: system libraries

The hard way to compile wgrib2 is to download the wgrib2_nolib.tgz.(VERSION).  
This file does not contain the libraries except for customized g2clib and iplib 
libraries.  You have to make sure the needed libraries included with wgrib2.tgz 
are installed and then you have to change the makefile so that the libraries 
are linked in.  You are on your own with this tarball.


                  built-in libraries               use system libraries

size              big executable                   small executable
library fixes     hard                             easy
                  (need to recompile wgrib2)
note:                                              usual method for system software

libraries         use as is                        must install missing libraries
makefile          use as is                        must be customized
makefile support  yes                              no
compile           easy                             not so easy


Note: I use/test wgrib2 with the built-in libraries. I only test compatability with
libraries included with the wgrib2.tgz tarball.  


Note: g2clib has bug fixes which are not in the official release.  The included
bug fixes make it into the official release at a much later date.  Please do
no link in the official g2clib.  You can blame me for bug that I made but
I don't want to be blamed for someone else's bugs.
