1/2008                         INSTALLING on Linux

On a bog-standard linux box, type "make" in the grib2 directory.  If all 
goes well, you will get the wgrib2 program in wgrib2/wgrib2.  Most
of the problems are caused by missing packages.  The missing packages
could include gcc, make, the developement png library and the development
z library.  Note, you need the development png and z libraries because
they include the headers.

I you don't have the png and z libraries, you can try 

   make -f makefile_all_libs

and it may work.  It is hard to test this configuration as I don't
have a system with both png and z libraries missing.


                        INSTALLING on windows XP

On the cygwin development system, you need to install many packages.
Please install the jasper library because the included jasper source
code has some problems compiling.  Once the makefile points to the
pre-compiled jasper headers/library, the code can be compiled.
See makefile_sys_jasper.


                        INSTALLING on FreeBSD

Try make -f makefile_all_libs.

                          Comments Netcdf

The netcdf library is included with this distribution.  The library is 
compiled in enable-C-only mode only so it may not be that useful for 
generic code.  So you can change the makefiles to point to a pre-existing 
netcdf library if desired. 


                               Problems

1) compiling jasper
2) compiling netcdf
3) missing libraries (png, z)

These are problems best addressed by someone who knows the system.
For example if you have Linux distribution, XYZ, you would be wise
to consult a computer savy person familiar with XYZ.
