[gmx-users] problems during make : undefined reference to `__ctype_b'

[Vanessa Oklejas]

Hi All,

I'm trying to install gromacs-3.1.4 onto a linux cluster with Red Hat 
v 7.3.  After executing 'make' i get the following printed to the screen:

: undefined reference to `__ctype_b'

function `read_int':

Any ideas as to what is causing this?

Thanks,
