Yet another tutorial on how to install WRF

Several tutorials on how to install WRF are available online.
Basically the common root is the Official Tutorial from mmm.ucar.
Some other noticeable websites are:

• WRF on Ubuntu server 16.04
• again WRF on Ubuntu server 16.04
• WRF on CENTOs
• WRF on Archlinux (with some nice ncl examples)
• WRF on a generic Linux machine 
• WRF Forum (section Installation) 
• etcetc... 

Among the several tutorials you find online I'd like to add another (useless?) guide (or script) I used to automate the compilation of the WRF/WPS systems, with some special notes.

It is definitely a non-exhaustive script and it might have some (hopefully non-destructive errors), so.... 
>>>use at your own risk<<<

The prerequisites are:

• the netcdf libray (version 4.x) successfully compiled and installed (here in /usr/local)
• gcc, gfortran (version 5.4.0 or higher)

 #!/bin/bash  
 # It is supposed that you have the following sources files in $SRCDIR  
 # ARWpost_V3.tar.gz        mpich-3.0.4.tar.gz  WRFV3.9.1.1.TAR.gz  
 # DTC_upp_v3.1.1.tar.gz      jasper-1.701.0.tar.gz netcdf-4.1.3.tar.gz zlib-1.2.11.tar.gz  
 # libpng-1.6.34.tar.gz      WPSV3.9.1.TAR.gz  
 # and it is supposed that you're using the same C/Fortran compiler  
 # used to build the NetCDF libray (in /usr/local)

Besides this script, I'd suggest to install also some complementary tools/software:

• ncview
• grads 2.0.2 or higher
• grib2ctl
• g2ctl
• eccodes
• wgrib
• wgrib2
• ncl 6.3 or higher
• arwpost
• ...
