I don&#39;t know why a standard location like /usr/lib isn&#39;t be detected as containing the libraries, but you can set LDFLAGS and CPPFLAGS accordingly so that the libraries and headers are found.  See the installation instructions for details.<br>

        Dear users, I have installed FFTW3 successfully, and confirmed<br>
        its location using locate:<br>

        However, when I try installing Gromacs 4.5.3 the -/configure<br>
        step yields:<br>
<br>
        configure: error: Cannot find fftw3f library<br>
<br>
<br>
        What am I doing incorrectly?<br>
<br>
<br>
    Without seeing the command you gave to configure, it&#39;s impossible to<br>
    say.<br>
