install Gromacs 5.0.7 with latest cmake-3.4.2 and fftw-3.3.4. I use below
Cmake command to install.

"cmake .. -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON"

I am newbies gromacs user. I am trying to execute the Bevan Lab tutorial
(Lysozyme in water). my first command is

"gmx pdb2gmx -f 1AKI.pdb -o 1AKI_processed.gro -water spce"

It execute properly. But when i execute number 15 force
field(OPLS-AA/L) at the end there is a massage "illegal instruction
(core dumped)". And in my directory only topology file create. No
gromacs output file Created "1AKI_processed.gro".

Any help greatly appreciated.
