I cannot reproduce this with HP-UX 11.31 and master + 3.7.

I opt to close this one.

[Jim Schneider]

Jim Schneider jim.schnei...@dataflux.com added the comment:

Martin - sys/_mbstate_t.h provides a definition for mbstate_t only (at least 
on HP/UX 11i V2.0).  I can verify that the problem still exists for Python 
3.2.1.  I am working on a workaround for this issue, and I will attach a patch 
once I get it to build.

[Jim Schneider]

Jim Schneider jim.schnei...@dataflux.com added the comment:

I got it to build on HP-UX 11.  However, there are a lot of compiler warnings 
about type mismatches, the _ctypes, _multiprocessing and termios modules failed 
to build, and make test died after not finding a usable binascii module.

To get it to build, I did the following:
1)  Applied the patch I attached to issue 12561
2)  Created a directory sys, and copied /usr/include/sys/stdsyms.h into it.
3)  Did chmod 644 on sys/stdsyms.h and applied the patch stdsyms.patch that 
I've attached to this issue to it.
4)  Ran configure with the argument CPPFLAGS=-I.

At this point, make ran to completion, and produced a python binary.  However, 
make test dies within seconds of starting up.

[Martin v . Löwis]

Jim, the question remains why it fails to compile then. If the type is defined, 
why does it give an error message but has not been defined as a type???

[Jim Schneider]

Jim Schneider jim.schnei...@dataflux.com added the comment:

Martin - sys/_mbstate.h is only included if _INCLUDE__STDC_A1_SOURCE is 
defined.  The only way this gets defined in the vendor-provided include files 
is if _XOPEN_SOURCE is defined and is equal to 500, or __STDC_VERSION__ is 
defined and is greater than or equal to 199901.

I've attached a patch to broaden the _XOPEN_SOURCE case (as the test should 
clearly have been =, not ==).  Defining __STDC_VERSION__ to 199901 or greater 
will also do the job, but it feels more like a hack than just fixing what's 
broken in the vendor include files.

 If you are no longer working on this, I think we should close as 
 languishing/postponed.

I am not working on this yet (its low prio), but will try building 3.2 on HP-UX 
once 3.2 final is released.

I've attached the files you requested.

 As a wild guess, try defining _XOPEN_SOURCE to 500, 
 i.e. -D_XOPEN_SOURCE=500.

Yes, this works .. the file compiles. I tried modifying the value of 
_XOPEN_SOURCE to 500 in pyconfig.h (currently set to 600). While fixes 
the mbstate_t error .. it results in in-numerous other errors.

That's an HPUX bug then, please report it to HP. They should assume
that any feature present in XPG 5 is also present in any later version.

 While fixes 
 the mbstate_t error .. it results in in-numerous other errors.

Well, we absolutely need mbstate_t, so we need to resolve all these
other errors.

Please be prepared for this becoming a many-months project. I don't
know what you need the HP-UX port for - maybe it would be best to hire
somebody who knows HP-UX, C, and Python.

Sridhar Ratnakumar sridh...@activestate.com added the comment:

Hello Martin,

My apologies for responding so late.


[Martin] Also, please confirm a few things: a. configure has detected 
that your system has mbrtowc (...)

# Yes, as can be seen in the attached config.log

[Martin] (...) b. configure's analysis is correct, i.e. your system has 
mbrtowc indeed.

# Yes, `mbrtowc` is present as the following C programs compiles and 
runs successfully:

  #include wchar.h
  int main()
  {
printf(Init\n);
mbrtowc(NULL, , 1, NULL);
  }

[Martin] does your system provide the mbstate_t type? if so, what 
header file needs to be included?

`mbstate_t` seems to exist in /usr/include/wchar.h .. however, 
including wchar.h does not seem to work:

bash-2.04$ cc +DD64 -Ae -D_REENTRANT +Z --version  
cc: HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]
bash-2.04$ cat test.c
#include wchar.h
int main()
{
  mbstate_t foo;
  printf(Init\n);
  mbrtowc(NULL, , 1, NULL);
}
bash-2.04$ cc test.c -o test 
Error 419: test.c, line 6 # 'mbstate_t' is used as a type, but has 
not been defined as a type.
  mbstate_t foo;
  ^ 
bash-2.04$ aCC test.c -o test
Error 403: test.c, line 8 # Undeclared variable 'mbrtowc'. Perhaps 
'mbtowc' as in int mbtowc(wchar_t *,const char *,unsigned long) [/
usr/include/stdlib.h, line 169] was intended.
  mbrtowc(NULL, , 1, NULL);

[issue5999] compile error on HP-UX 11.22 ia64 - 'mbstate_t' is used as a type, but has not been defined as a type

[Martin v . Löwis]

Martin v. Löwis mar...@v.loewis.de added the comment:

 `mbstate_t` seems to exist in /usr/include/wchar.h

I can't infer that from the copy of wchar.h that you provided. I
see that mbstate_t* is used, but I fail to find any definition
of mbstate_t.

I see that sys/_mbstate_t.h is included. This inclusion is conditional
on  _INCLUDE__STDC_A1_SOURCE, so a first check should be done whether
this is defined. In addition, it would be interesting to know what
_mbstate_t.h contains.

 bash-2.04$ cat test.c
 #include wchar.h
 int main()
 {
   mbstate_t foo;
   printf(Init\n);
   mbrtowc(NULL, , 1, NULL);
 }

It's best to focus on this example. Produce preprocessor output for
it, and attach that to the bug report.

This is standard C, AFAICT, so if the compiler fails to compile
it, something is wrong with the compiler, or you are using it incorrectly.

As a wild guess, try defining _XOPEN_SOURCE to 500, i.e.
-D_XOPEN_SOURCE=500.

 cf. http://www.mail-archive.com/lftp-de...@uniyar.ac.ru/msg00602.html

I don't think this is relevant. Somehow, they managed to #define
mbstate_t to int, breaking the header - this should not happen here.
