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 serial for your platform first to verify basic functionality. Note: Currently, the fire code will not work with choices that include <tt>sm</sm>, i.e., shared memory parallelism by OpenMP. 
Modify the configuration 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>
