Summary: configure not able to find ncurses/curses in Solaris 

Initial Comment:
I am trying to build Python 2.3.3 on Solaris 9 x86.
Everything goes fine except that I have some issues
with curses module ...

It looks like configure is failing to detect curses
found /usr/lib or any ncurses installed under system.

Other fixes:

1) I had to fix configure script in order to get it
running by changing

SunOS/5.6 in SunOS/5.*

eg.
"
case $ac_sys_system/$ac_sys_release in
  # On OpenBSD, select(2) is not available if
_XOPEN_SOURCE is defined,
  # even though select is a POSIX function. Reported by
J. Ribbens.
  # Reconfirmed for OpenBSD 3.3 by Zachary Hamm, for
3.4 by Jason Ish.
  OpenBSD/2.* | OpenBSD/3.[01234])
    define_xopen_source=no;;
  # On Solaris 2.6, sys/wait.h is inconsistent in the usage
  # of union __?sigval. Reported by Stuart Bishop.
  SunOS/5.*)
"

Im building python using 2.95 the GNU compiler.
The configure command was something like:

./configure --prefix=/usr/local --with-threads
--enable-shared

My LD_LIBRARY_PATH is defined as:

/usr/lib:/opt/sfw/lib:/usr/sfw/lib

I have tried passing to the command line
LDFLAGS="-L/usr/lib :/usr/sfw/lib -lcurses -ltermcap "
./configure .... without success
---

I have found that after compilation there are some
warnings about curses module ...

*** WARNING: renaming "_curses" since importing it
failed: ld.so.1: ./python: fatal: relocation error:
file build/lib.solaris-2.9-i86pc-2.3/_curses.so: symbol
newscr: referenced symbol not found
building '_curses_panel' extension

*** WARNING: renaming "_curses_panel" since importing
it failed: No module named _curses

... which, I think, will end by having no curses module
available.

>From help() found out these:

help> modules

Please wait a moment while I gather a list of all
available modules...
...
_curses_failed      getpass             py_compile
_curses_panel_failed 

So python 2.3.3 does not biuild 100% clean under
Solaris x86 
I havent tried this on sparc but most likely same
problem is in there too.

Please evaluate.

https://sourceforge.net/tracker/index.php?func=detail&aid=1012280&group_id=5470&atid=305470

I saw this bug on both 2.3.3 and 2.3.4 on Solaris 8 on SPARC

I think the problem is between GNU gcc compiler and autoconf ...
when Im using Sun's compiler and libcurses ... I see no
problem. 
python builds fine without any problem.

The problem is visible when Im using gcc and autconf does
not pick up the correct libcurses. At the moment Im
swithcing to Sun's compiler ...

More details found:

Looks like configure is not able to work with Solaris's
libcurses at all.
I have tried in one system which does not have libncurses at
all.

configure is failing to work with Solaris's libcurses.

Regarding this problem looks like 'configure' does not pickup
Solaris's curses library.
I had to manually pass to configure command libncurses library

LDFLAGS="-L/opt/sfw/lib -R/opt/sfw/lib -lncurses"
CPPFLAGS="-I/optsfw/include" ./configure --prefix=/usr/local
--with-threads --enable-shared

Does this mean that python needs libncurses and can not work
with Solaris curses library !?
