Fixing typo in SRC_URI. Also, there are some warnings about tuples being created in a depricated fashion in ncurses/curses.py (IIRC) which I don't know how to clean up. hth. # Copyright 1999-2002 Gentoo Technologies, Inc. # Distributed under the terms of the GNU General Public License, v2 or later # Author Gontran Zepeda <gontran@gontran.net> S=${WORKDIR}/${P} DESCRIPTION="A new ncurses binding for Python."

I get an undefined reference to trace from within the library with python 2.2. I'm trying to run the examples found in /usr/share/pyncurses-0.3/
It appears that trace is a debugging routine from ncurses -- possibly available from libncurses_g.a (which doesn't seem to exist on my system with ncurses-5.2-r3). Hoping don't need to modify curses ebuild for this to work -- but on the upside it's a curses debugging, not a core pyncurses, problem I hope. Curses doesn't seem to generate the debugging library -- looking into it.
OK. So if I modify the ncurses ebuild like so: src_compile() { #if [ -z "$DEBUG" ] #then # myconf="${myconf} --without-debug" #fi rm -rf test removing the --without-debug option for ./configure, libncurses_g.a is created. WHERE is DEBUG set anyway? This is fairly serious for pyncurses ebuild, since the trace call is explicitly an 'extern' type in _curses.c ... Maybe have an alternate ncurses-debugging ebuild which only builds and copies the libncurses_g.a lib to /usr/lib and is required by pyncurses? OK. Sorry, I've been writing this while fixing. IF I build and install the debugging curses library AND IF I use this modified pyncurses-gentoo patch (attached). The demo works! w00t! Question is how to get debugging lib for ncurses. help please. :) Here's the additional piece of diff: --- setup.py.orig Mon Apr 29 00:52:14 2002 +++ setup.py Mon Apr 29 00:52:29 2002 @@ -40,7 +40,7 @@ ext_modules = [('ncurses._curses', { 'sources': ['ncurses/_curses_wrap.c'], - 'libraries': ['ncurses'] + 'libraries': ['ncurses', 'ncurses_g'] }), ('ncurses._panel', { 'sources': ['ncurses/_panel_wrap.c'],
this fix requires both debug and release versions of ncurses installed. pyncurses hasn't been updated for two years. Maybe it's time to add optional debug support to the library.
Right there. Closing.
