Next, Solaris 8+ *does* have mvwgetnwstr, the problem is that it's in the X/Open version of the curses library, not the (old, stinky, backwards-compatible) default version of libcurses. Solaris 10's man pages do a much better job of explaining the differences, on 10 one can look at man -s 3xcurses libcurses vs. man libcurses If you want to compile and link against the X/Open version of the curses library, you need to have -I/usr/xpg4/include in CPPFLAGS and CFLAGS, and either -L/usr/xpg4/lib or -L/usr/xpg4/lib/64 (depending on whether you're compiling for ILP32 or LP64). /usr/xpg4/lib and /usr/xpg4/lib/64 are also not in the default loader search path, so you either need to modify the loader search path (man crle) or your also need a -R/usr/xpg4/lib or -R/usr/xpg4/lib/64 in LDFLAGS too. Because of the way the _cursesmodule is currently written, though, it assumes that if __sun is defined as a preprocessor symbol, STRICT_SYSV_CURSES should be defined, which actually causes problems if you try build with with newer X/Open curses. It should be possible to support building against either curses implementation on Solaris, but for now your patch at least makes _cursesmodule compile with the default version. ---------------------------------------------------------------------- Comment By: A.M. Kuchling (akuchling) Date: 2005-11-22 08:45 Message: Logged In: YES user_id=11375 One use of mvwgetnwstr in the module is replaced by a manual emulation of the function, if STRICT_SYSV_CURSES is true, but another use isn't replaced; I suspect this is the problem. I've attached a patch that ensures that mvwgetnstr() is only used when STRICT_SYSV_CURSES is undefined. Please let me know if this fixes the compilation problem. ---------------------------------------------------------------------- Comment By: Nelson Arzola (narzola) Date: 2005-10-29 03:01 Message: Logged In: YES user_id=39023 I would like to add that this problem also exists under Solaris 2.10. For some reason, mvwgetnstr is not defined under Solaris 10. When I use nm to get the symbols out of /usr/lib/libcurses.so.1, I do not find it. When I replace the two references in /dsk/data0/build/Python-2.4.2/Modules/_cursesmodule.c from mvwgetnstr to mvwgetnwstr, I was able to compile the module and pass the appropriate tests. Since I don't use curses, I really don't have a good way to test this. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1324799&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
