<div>Hi,<br> <br>To compile a single-precision version of the libraries and install FFTW version 3.2.<br> <br>I followed the steps inhttp://<a href="http://www.gromacs.org/Downloads/Installation_Instructions#Prerequisites">www.gromacs.org/Downloads/Installation_Instructions#Prerequisites</a> .</div>

<div>my computer characteristics:<br>Root at …fftw-3.2.2]# uname -a<br>Linux localhost.localdomain 2.6.31.5-127.fc12.i686.PAE #1 SMP Sat Nov 7 21:25:57 EST 2009 i686 i686 i386 GNU/Linux<br> <br>I used the following command:<br>

<br>I used "make distclean" and try to configure again with.<br> <br> <br>Root at …fftw-3.2.2]#./configure --enable-threads --enable-float --enable-sse --disable-shared<br> <br> <br>Root at …fftw-3.2.2]#./configure --enable-threads --enable-float --enable-sse --enable-shared<br>

<br>I get the same errors during FFTW version 3.2.2 compilation (the "make" step) as above.<br> <br>What commands are useful for compiling FFTW version 3.2.2 on my computer?</div>
