Compiling netcdf with ifort 9.1 on an Intel Mac

First, if you haven't already done so, you need to do this if you are runing Xcode 2.3, like I am. Otherwise, ifort will not make it through configure.

cd /usr/lib
sudo ln -s gcc/darwin/3.3/crt2.o .

Then, you can set up your environmental variables just like you would using ifort in Linux. For example:

export FC=ifort
export F90=ifort
export FFLAGS="-O -mp"
export CPPFLAGS="-DNDEBUG -DpgiFortran"

Then, like always, run

./configure --prefix=/usr/local
make
