New submission from R. Jones:
I am trying to compile Python-2.7.10. This is being done as a user, not root
and I don't have access to /usr/local other than to avoid all the broken stuff
in it.
My local is /appl/local
I am installing Python in /appl/local/python-2.7.10
I have ncursest as part of my /appl/local, but python keeps wanting to link
with /usr/ccs/lib/libcurses.so. UGH.
"ncursest" was built instead of "ncurses" because I used "--with-pthread" and
"--enable-reentrant"
I rebuilt ncurses without those two flags but with --with-termlib which built
libtinfo.so. When compiling the _curses module, I get this error:
*** WARNING: renaming "_curses" since importing it failed: ld.so.1: python:
fatal: relocation error: file
build/lib.solaris-2.10-sun4u.32bit-2.7/_curses.so: symbol _unctrl: referenced
symbol not found
In this case I can see unctrl is in tinfo...but no matter what I do, I cannot
get it to add -ltinfo to the link line.
$ nm -s libtinfo.so | grep unctrl
0001d4f8 T unctrl
00039170 r unctrl_blob.5682
00039070 r unctrl_c1.5681
0001d30c T unctrl_sp
00039572 r unctrl_table.5680
So my next attempt was to make a private copy of ncurses for Python without
--with-termlib, but had to add --enable-termcap and install it in
/appl/local/python-2.7.10/lib
$ ls -al /appl/local/python-2.7.10/lib

Unfortunately I see this in /usr/ccs/lib/libcurses.so
$ nm /usr/ccs/lib/libcurses.so | grep unctrl

I don't see any reference to unctrl except this:
./Modules/_cursesmodule.c: knp = unctrl(rtn);
./Modules/_cursesmodule.c: return PyString_FromString(unctrl(ch));
./Modules/_cursesmodule.c: {"unctrl",
(PyCFunction)PyCurses_UnCtrl, METH_VARARGS},
none of which is referencing _unctrl
so it seems that python can never work with ncurses6...even though it seems
there is support for it in the code.
Any help?
