Description of Problem: I develop a library using curses for my software. This with /usr/include/curses.h defined in RedHat 7.0. In RedHat 7.2 this include change. In RedHat 7.0 the "ldat" structure is defined for four fields. In RedHat 7.2 the "ldat" structure is defined for zero field. This is my problem. When I compiling my library this error is display: "imcomplete type". Version-Release number of selected component (if applicable): NCURSES_VERSION "5.2" How Reproducible: Try to insert a character in "stdscr" using the "curses.h" definition. Steps to Reproduce: 1. Develop a little program using "stdscr" structure 2. Insert a space in a line manipulating "stdscr" 3. gcc Actual Results: gcc fail and I don't know why. If I use NCURSES_VERSION "5.1" I don't have problem. Expected Results: Tell me if is a bug or is my bug. And tell me how I can fixed(please). I would like use NCURSES_VERSION "5.2" in my applications Additional Information: Thanks for your time.

This is because ldat is a private structure and you aren't supposed to manipulate it directly in your code. Older versions of ncurses just didn't enforce it. Really evil workaround to keep your old code working: Replace #include <curses.h> with #define ldat __ldat #include <curses.h> #undef ldat struct ldat { chtype *text; NCURSES_SIZE_T firstchar; NCURSES_SIZE_T lastchar; NCURSES_SIZE_T oldindex; }; The proper fix is not using ldat directly.
