You need libncurses.so.4
.
Easysoft build the unixODBC Driver Manager with readline
support using ncurses4
in an attempt to make it compatible with as many Linux distributions as possible. Some Linux distributions don't install compatibility libraries by default, and only include the latest library versions.
We have had this reported for Red Hat. Install ncurses4-5.0-9i386
or later from your Red Hat distribution.
Alternatively, build unixODBC yourself. Get the ncurses4
source distribution and build it yourself.
