The _curses module has two issues on OpenSolaris: - using the default curses library, mvwchgat() cannot be found and _curses module compilation fails - there is a "XPG4 curses" library. I tried to use it using various hacks in _cursesmodule.c and setup.py, but test_curses failed with a crash. - if the readline library (not the Python module) is linked to libncursesw, the compilation of the _curses module fails because cchar_t is not defined. I suppose that curses.h is the bytes library, not the ncursesw Unicode library. See issue #12567 for the ncursesw issue and issue #3786 for the mvwchgat() problem. The issue #3786 contains information about XPG4 curses and has a (non working) patch for the mvwchgat() issue. -- I opened a new issue because #12567 is more specific to Unicode, and #3786 talks about various issues (it is not specific to curses).
Jesús Cea Avión also noticed in from the issue #6755: I have compiled ncurses myself, supporting wide characters. I get this warnings in the buildbots: """ /export/home/buildbot/32bits/3.x.cea-indiana-x86/build/Modules/_cursesmodule.c:920: warning: implicit declaration of function 'wget_wch' /export/home/buildbot/32bits/3.x.cea-indiana-x86/build/Modules/_cursesmodule.c:927: warning: implicit declaration of function 'mvwget_wch' /export/home/buildbot/32bits/3.x.cea-indiana-x86/build/Modules/_cursesmodule.c:2760: warning: implicit declaration of function 'unget_wch' """ Studying the "ncurses.h", I see the definition of "wget_wch" and others. But these definitions are created only if "_XOPEN_SOURCE_EXTENDED" is defined. Something to be explored?.
Does OpenIndiana ship with the gnu version of ncurses like Solaris 11? Headers: /usr/include/ncurses Libraries: /usr/gnu/lib If it matches Solaris, then you can use my patch[1] in issue 3786 to see if that works around the issue, like it does for Solaris. 1) http://bugs.python.org/file26171/bug3786.patch
