Summary: configure weaknesses on HP-UX

Initial Comment:
1. configure doesn't handle HP-UX release numbers
(e.g., B.11.00), resulting in MACHDEP = "hpuxB".

2. After checking for wchar.h, configure doesn't
include it when checking the size of wchar_t.

(Python 2.2b1 on HP-UX 11.00)

On the curses problems, please check out the latest CVS
again; it is supposed to be fixed on HP/UX 11.

Thanks for the list. Can you submit separate patches or bug
reports for the things you know need work? That seems easier
than holding this conversation in an unrelated closed bug
report. :-)

OPT is *not* the right place for a -I option, but there's
currently no "right" place. I've seen them added to "CC",
which makes more sense to me.

Is HP-UX 10.20 still relevant? If so, it might be nice if
the configure script defaulted to --without-threads. (Is the
problem that -lcma has pthread_create but in fact doesn't
support the rest of the PTHREAD API?)

Yes, it passes the thread tests.

Other things that I'm aware of (if not noted otherwise, I
haven't done further investigations yet):

On HP-UX 10.20 and 11:

- Building the curses module (Bug #432497): I've got a patch
for configure.in, but I'm not sure if OPT is the right place
to prepend a -I option--shall I attach it to bug #432497?

- test_locale is skipped: This is only because HP-UX uses
en_US.iso88591 instead of en_US patch for test_locale.py
attached.

- configure detects large-file support, but test_largefile
is skipped

On HP-UX 11, when building a 64-bit (LP64) executable (don't
know if anybody wants to do this):

- curses can't be built.  This *might* be because there's no
64-bit libtermcap

- test_socket and test_time fail.

On HP-UX 10.20:

- It is not clear which threads work. DCE threads seem not
to work (tested), GNU pth should work (not yet tested).
However, configure detects pthread_create in -lcma, so that
the build fails if --without-threads is not specified (this
is acceptable, I think, if it's documented).

- Even if building --without-threads, 7 tests failed:
    test_fpformat test_mimetypes test_pyclbr test_socket
test_sundry
    test_urllib test_urllib2.

(I'm currently doing all builds with HP C)

Do the tests for threads pass? (test_thread.py,
test_threading.py, test_threaded_import.py,
test_threadedtempfile.py) That would be great news!

If there are any other problems on HP-UX, it would be great
if you could help out. Do you know what those problems are?

Thist patch has no effect on threads.  However, threads do
work (i.e., are recognized by configure) on HP-UX 11 since
2.2b1 (I just wanted to submit a patch to the 2.2a4
configure.in when 2.2b1 was released).  I am willing to
support you regarding HP-UX, if necessary (there still seem
to be some open issues).

Thanks! Checked into CVS.

With this patch, do threads work on your system? (We've had
long-standing complaints that Python can't be built with
threads on HP-UX 11, but these are hard to verify for us. It
would be great if we could say with confidence that this is
fixed in 2.2b2.)
