EKIT.patch is not correct: it fails to find mvwchgat() on Linux, whereas the function is present. The test program is not linked to curses nor ncurses.
<< Solaris has both traditional System V curses and an XPG4-compatible
curses that does include mvwchgat. The traditional system V curses is
the default, for backward compatibility.
...
- rebuild readline to use XPG4 curses, and then rebuild every single
application that links against readline. Then build Python, using
the -I and -L/-R flags to get XPG4 curses for the entire Python build.
- modify the setup.py for the _curses module so that
logic is added for Solaris to look for the XPG4 curses only during
the build of the _curses module. >>
Link _curses module to a different curses library than the library used by readline may lead to crash: see issue #7384.
