In general initscr() ought to work. It fails if it has no/a wrong
idea of what your terminal is.

In the same shell as you run run your program type

set | grep -i term

Now some entry should show up, e.g.
TERM=xterm

infocmp $TERM

should fetch information about your terminal, from the same source
as curses does.

Possible problems are:
- your operating system/configurations lies to curses about the terminal
  or your terminal is not specified at all
- curses has not been properly installed and cannot find the database
