h1. Building NetCDF with intel's openMPI

To build netCDF with openMPI based on intel compiler, first you have to folow this steps [[Building OpenMPI with intel compiler]], then:

<pre><code class="bash">

export CC=mpicc

export F77=mpif77

export F90=mpif90

export FC=mpif90

#export LIBS="-lirc"

export CFLAGS="-fPIC -DgFortran" 

export CXXFLAGS="-fPIC -fno-second-underscore -DgFortran" 

export FFLAGS="-fPIC -fno-second-underscore -DgFortran" 

export F90FLAGS="-fPIC -fno-second-underscore -DgFortran"

export LDFLAGS="-fPIC"

./configure --prefix=/opt/netcdf --disable-shared --disable-dap --enable-f90 

make -j 64  # or the number of cores you have

</code></pre>

Then to install it, you must do it as super user:

<pre><code class="bash">

sudo make install

</code></pre>

Once installed you need to tell the linker the library path, to do so:

<pre><code class="bash">

su root  #sudo -s on ubuntu

echo "/opt/netcdf/lib" > /etc/ld.so.conf.d/impinetcdf.conf

ldconfig  #Tell the linker to update cache

exit  #leave root session

</code></pre>
