Dear All

I am trying to install 4.5.5 on my mac. I have installed fftw3 with
--enable-float, and have used the CPPFLAGS and LDFLAGS options in my
.bashrc file. GROMACS still complains that "configure: error: Cannot find
fftw3f library".

Why is it not able to find the libraries?

Here are the specific details:

content of .bashrc:

export CPPFLAGS="-I/usr/local/include"
export LDFLAGS="-L/usr/local/lib"

% ls /usr/local/lib/*fft*
/usr/local/lib/libfftw3f.a /usr/local/lib/libfftw3f.la

% ls /usr/local/include/*fft*
/usr/local/include/fftw3.f /usr/local/include/fftw3.f03
/usr/local/include/fftw3.h /usr/local/include/fftw3l.f03

Any ideas what might be going wrong?

Thank you
