Dear Justin, Thanks very much for your reply! Yeah, I did not add the option of --enable-shared for compilation of gromacs 4.5.4, but it still failed after I added this option for the compilation. For the compilations I posted in the last e-mail, I do add the option of --enable-shared in compilation of fftw 3.3, but not for compilation of gromacs 4.5.4. Problem remains unsolved.
I choose this old version is to keep the simulations consistent with previous simulations. Thanks for the suggestion!
