Re: [AMBER-Developers] When is fftw3.f03 created?

On my Mac (OS X 10.7.3 Lion), GCC 4.4.6, I get no errors with the following

cd $AMBERHOME && git clean -f -x -d

./configure --with-python /usr/bin/python --with-netcdf /opt/local
-macAccelerate gnu
make -j4 install

./configure --with-python /usr/bin/python --with-netcdf /opt/local
-macAccelerate -mpi gnu
make -j4 install

On my Ubuntu machines (ifort and gcc4.6), I get no errors with the above
workflow either adjusted for my new location of NetCDF, and removing
-macAccelerate and --with-python (on a fresh, clean checkout using "git
clean -f -x -d" in $AMBERHOME). I may try GCC 4.5.3 on my Mac when I get a
chance, but I don't see these errors...
