sciteco/m4/ax_with_curses.m4, branch v2.5.2 Scintilla-based Text Editor and COrrector curses: fixed configuration for native netbsd-curses and ncurses (several corner cases) 2025-08-18T23:30:36+00:00 Robin Haberkorn robin.haberkorn@googlemail.com 2025-08-17T19:12:37+00:00 9ec7d0f1e6ee4f7f45b4950d483006ab53786901 * pkg-config check for `ncurses` fails if it failed previously for `ncursesw`. This is the case e.g. for ncurses from NetBSD's pkgsrc. * No longer assume that any libncurses is not enhanced (X/Open compatible). * SciTECO and Scinterm require to find a curses.h in the include paths. The ncurses check must therefore not be limited to the first best ncurses/ncurses.h and the like. * We now always check for X/Open compatibility and always require a curses.h in the standard directories or as given by pkg-config. * AX_WITH_CURSES was radically rewritten and is now called AX_WITH_NCURSES. * --with-interface=netbsd-curses gets its own detection code. It always requires a curses.h in the standard paths and a libcurses. It should now be fixed for real NetBSD installations if the ncurses port is installed as well. * Unified all of the curses-arguments to CURSES_CFLAGS and CURSES_LIBS. There is no reason we need PDCURSES_CFLAGS, XCURSES_CFLAGS etc.

  It should now be fixed for real NetBSD installations if the ncurses
  port is installed as well.

added AX_WITH_CURSES for more robust ncurses checks 2024-12-24T11:08:06+00:00 Robin Haberkorn robin.haberkorn@googlemail.com 2024-12-24T10:57:38+00:00 caed2e42c7257a386ed433a8bccba028cc9437c8 * Turns out that on SunOS/OmniOS the ncurses port does not ship with a ncursesw pkg-config file, but the ncurses file is for a version, that does contain widechar support as well. * Instead of adding yet another recursive PKG_CHECK_MODULES() call, we now use the AX_WITH_CURSES() macro, which is probably more robust. This should at least fix ./configure on OmniOS. * It also adds a number of feature C macros, that could be useful to check in the future. * At the moment, we strive to support all X/Open-compatible Curses libraries, but both enhanced and color functions are required. Therefore plain SVr4 Curses is not supported. * source: https://www.gnu.org/software/autoconf-archive/ax_with_curses.html 
* Turns out that on SunOS/OmniOS the ncurses port does not ship with
  a ncursesw pkg-config file, but the ncurses file is for a version,
  that does contain widechar support as well.
* Instead of adding yet another recursive PKG_CHECK_MODULES() call,
  we now use the AX_WITH_CURSES() macro, which is probably more robust.
  This should at least fix ./configure on OmniOS.
* It also adds a number of feature C macros, that could be useful to
  check in the future.
* At the moment, we strive to support all X/Open-compatible Curses
  libraries, but both enhanced and color functions are required.
  Therefore plain SVr4 Curses is not supported.
