How to build WRF4

==

Getting the source code

From our fork

git clone git@github.com:openwfm/WRF.git

or from the official repository

git clone git@github.com:wrf-model/WRF.git

Use the master branch for the current release (default), or

git checkout develop

to include all developments accepted to date.

Coming soon: branch with updated fire model.

All platforms

Set up the environment as needed, then

cd WRF
./configure
<pre>
Use <tt>./configure -d</tt> for faster build and to enable debugging. Choose <tt>serial</tt> for your platform first to verify basic functionality. Note: Currently, the fire code will not work with choices that include shared memory parallelism by OpenMP, i.e., <tt>smpar</tt> or <tt>sm+dm</tt> 
This creates the file <tt>configure.wrf</tt>. Edit <tt>configure.wrf</tt> as needed, then
./compile em_fire >& compile.log

Check for errors and warnings

grep Err compile.log
grep War compile.log

and test the code built with serial:

cd test
cd em_fire
./ideal.exe
./wrf.exe
</exe>

==University of Utah CHPC==
===Set up the environment===
<pre>
module load intel/18 impi/18 netcdf-f
setenv WRFIO_NCD_LARGE_FILE_SUPPORT 1
setenv NETCDF /uufs/chpc.utah.edu/sys/installdir/netcdf/i18
setenv JASPERLIB /uufs/chpc.utah.edu/sys/installdir/jasper/1.900.1-atmos07102015/lib 
setenv JASPERINC /uufs/chpc.utah.edu/sys/installdir/jasper/1.900.1-atmos07102015/include 

In ./configure, select 13 - INTEL (ifort/icc) and serial.

Modify the configuration

Edit configure.wrf: Add to INCLUDE_MODULES

 -I$(HDF5_INCDIR)

and add to DEP_LIB_PATH

  -L$(HDF5_LIBDIR)
