Hello Mailinglist! i'm using cygwin together with perl 5.14 and the Curses::UI perl module. It uses the ncursesw library bundled with cygwin.
Installing the Curses::UI worked well using cpan, but using the ncurses functions like getyx() from the demo-script bundled with the curses module crahes perl with the error-message: Curses function 'getyx' is not defined in your Curses library at demo line 59. Looking into /usr/include/ncursesw/cursesw.h shows that this macro is defined. Even building the Curses module for perl by hand, reveals that there is something wrong with the ncurses library: ~/Curses-1.28 $ export CURSES_LDFLAGS="-L/usr/lib/ncurses -lncurses" ~/Curses-1.28 $ export CURSES_CFLAGS="-I/usr/include/ncurses" ~/Curses-1.28 $ perl Makefile.PL GEN function: not applicable PANELS functions: not enabled MENUS functions: not enabled FORMS functions: not enabled Writing Makefile for Curses Writing MYMETA.yml ~/Curses-1.28 $ perl test.syms -v PANELS MENUS FORMS Checking capabilities of the Ncurses libraries. Set CURSES_VERBOSE environment variable to see the details of the tests.

I tested this on two different OS (Win7 and XP) with the latest version of cygwins libncursesw. Is the macro missing in the library itself? What could i do to make it working?
