Installation

system check

create a Test folder

mkdir TESTS
cd TESTS

Download the test cases and start tests, the output of tests should include SUCCESS

wget https://www2.mmm.ucar.edu/wrf/OnLineTutorial/compile_tutorial/tar_files/Fortran_C_tests.tar
tar -xf Fortran_C_tests.tar

gfortran TEST_2_fortran_only_free.f90
./a.out
gcc TEST_3_c_only.c
./a.out
gcc -c -m64 TEST_4_fortran+c_c.c
gfortran -c -m64 TEST_4_fortran+c_f.f90
gfortran -m64 TEST_4_fortran+c_f.o TEST_4_fortran+c_c.o
./a.out
./TEST_csh.csh
./TEST_perl.pl
./TEST_sh.sh

create a library folder and install the library

mkdir Build_WRF
cd Build_WRF
mkdir LIBRARIES
cd LIBRARIES

download and unzip the required libraries.

tar xzvf libpng-1.2.50.tar.gz

7. MPICH

module load mpich

Choice 1: Install the library(with the HDF5 support and without PnetCDF support)

set the environment variables

export DIR=/PATH/TO/Build_WRF/LIBRARIES
export CC=gcc
export CXX=g++
export FC=gfortran
export F77=gfortran
module load libxml2

1. install the zlib

cd zlib-1.2.11/
./configure --prefix=$DIR
make
make install

2. install the hdf5

cd hdf5-1.12.2/
./configure --prefix=$DIR --with-zlib=$DIR --enable-hl --enable-fortran
make check
make install
export HDF5=$DIR
export LD_LIBRARY_PATH=$DIR/lib:$LD_LIBRARY_PATH

3. Build NETCDF-C

cd netcdf-c-4.9.2
export CPPFLAGS=-I$DIR/include
export LDFLAGS=-L$DIR/lib
 ./configure --prefix=$DIR --disable-dap
make check
make install
export PATH=$DIR/bin:$PATH
export NETCDF=$DIR

4. build NetCDF fortran library links with NETCDF-C, after successful installation, netcdf.inc will be ${NETCDF}/include file. For sometimes, it will show C compiler stop working, Please check the environment variable in LIBS="-lnetcdf -lhdf5_hl -lhdf5 -lz", make sure netcdf and hdf5 path in the environment variables.

export LD_LIBRARY_PATH=$DIR/lib:$LD_LIBRARY_PATH
export CPPFLAGS="-I${DIR}/include -I/usr/include"
export LDFLAGS="-L${DIR}/lib -L/usr/lib"
export LIBS="-lnetcdf -lhdf5_hl -lhdf5 -lz" 
./configure --prefix=$DIR --disable-shared
make check
make install

5. Install the WRF

cd ..
wget https://github.com/wrf-model/WRF/releases/download/v4.5.1/v4.5.1.tar.gz
tar xvzf 4.5.1.tar.gz
cd WRFV4.5.1
module load adios2
export ADIOS2="/mnt/repo/software/spack/spack/opt/spack/linux-ubuntu22.04-skylake_avx512/gcc-11.3.0/adios2-2.9.0-mmkelnu4f4f4hpejrpdwofyrnguat27y
export HDF5=$DIR
export NETCDF=$DIR
./configure

Please select from among the following Linux x86_64 options: Choose 34(dmpar), Compile for nesting? choose 1. If configure is done, you can see a configure.wrf file in the folder.

./compile em_real
 #./compile em_real >& log.compile
export WRF_DIR=PATH/to/WRF4.5.1

You can see the following information shows the installation is successful.

To check check whether it was successful

ls -ls main/*.exe

If you compiled a real case, you should see:

wrf.exe (model executable)
real.exe (real data initialization)
ndown.exe (one-way nesting)
tc.exe (for tc bogusing--serial only)

Choice 2: Install the libarary(with both HDF5 support and PnetCDF support)
