<DIV>Dear gmx-users,</DIV>
<DIV>&nbsp;</DIV>
<DIV>When&nbsp;I&nbsp;parallel install gromacs-4.0.4. I encountered&nbsp;the 
problem.&nbsp;The following&nbsp;is my installation steps.</DIV>
<DIV>&nbsp;</DIV>
<DIV>Step 1: install fftw-3.1.2</DIV>
<DIV>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # cd 
fftw-3.1.2</DIV>
<DIV>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # ./configure 
--enable-float --enable-mpi -enable-threads</DIV>
<DIV>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # make</DIV>
<DIV>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # 
make&nbsp;install</DIV>
<DIV>Step 2:&nbsp;install gromacs-4.0.4</DIV>
<DIV>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # cd 
gromacs-4.0.4</DIV>
<DIV>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
#./configure&nbsp; --enable-mpi --with-fftw3 --program-suffix=_mpi 
--enable-shared&nbsp;&nbsp; --enable-sse</DIV>
<DIV>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # 
make</DIV>
<DIV>then I encountered the following&nbsp;errors:</DIV>
