[gmx-users] installation errors

[mah maz]

Dear all,
I am trying to install a new version of gromacs(rather than rpm) on my
system. I apply these commands:(in root while im superuser)
tar -xzvf fftw-3.3.4.tar.gz
cd fftw-3.3.4
./configure --enable-float --enable-threads
make
make install

and for gromacs:

tar -xzvf gromacs-4.5.5.tar.gz
cd gromacs-4.5.5
./configure
make
after this command the following errors occur:
can not be used when making a shared object
recompile with -fPIC
/usr/local/lib64/libfftw3.a:couldnt read symbols:bad value
collect2: error: ld returned 1 exit status
make[3]:***[libmd.la] error1
make[3]: leaving directory '/gromacs-4.5.5/src/mdlib
make[2]: [all-recursive] error1
make[2]: leaving directory '/gromacs-4.5.5/src
make[1]: error2
make[1]: leaving directory '/gromacs-4.5.5/src
make***[all-recursive] error1
what should i do? is it because of the incompatibility of the
fftw version and gromacs version?
thanks!
