I'm no compiler expert, but is it necessary to set all these CFLAGS here? Does
the installation fail for some reason if they're not set?
Also, how is Gromacs finding FFTW? You haven't set the CPPFLAGS or LDFLAGS.
make -j 48
make install
I had installed the gromacs version 4.5.3 earlier and encountered the
same problem with pdb2gmx. Hence installed the latest version.
This would indicate to me that the problem is not necessarily in Gromacs, but
the way you're installing it, and as Mark suggested, is probably related to some
static/shared library issue.

Any hints will be appreciated.
Please provide the exact commands that you used to install Gromacs.
What exactly were the issues that you had to circumvent? Have you
installed previous versions of Gromacs that have worked, such that
this problem is specific to 4.5.4?

Probably, no other GROMACS command works either, because of some
shared
library issue related to your new installation.
