PROBLEM:
I get the error "Cannot open console device" on Linux as soon as I try to run DataFlex 3.1d.
This usually happens when trying to run DataFlex 3.1d with a newer version of Linux than it was tested with, for example, using Red Hat 5.1 or 6.0.

DataFlex 3.1d was tested on these versions of Linux:
Red Hat version 5.0, kernel 2.032
Caldera version 1.2, kernel 2.033

SOLUTION 1:
The TERMINFO environment variable needs to be set to where Linux's terminfo files are.
Do NOT point them to the directory where DataFlex's terminfo files are, but to the directory where Linux's terminfo files are.


SOLUTION 2:
The location for the terminfo files was changed from /usr/lib/terminfo (ncurses 1.9.9e) to /usr/share/terminfo (ncurses 1.9.9g).
Make the symlink /usr/lib/terminfo point to /usr/share/terminfo, by doing 'ln -s /usr/lib/terminfo /usr/share/terminfo'.


SOLUTION 3:
This problem is sometimes caused by dfsetup's failure to determine the screen size. You can solve this problem by setting the LINES and COLS environment variables.

NOTE: You can add this code to the bottom of your setup script:

//CODE:
LINES=25
COLS=80
export LINES COLS
//CODE_END
