Hi python maintainer,
Is there any chance to get a build of python 3.3 on x86_64? (I need
PEP 380, delegating to a subgenerator, and the Windows version doesn't
play nice with cygwin shells). I tried downloading the sources and
applying the patches mentioned in the .cygport file for the cygwin
python 3.2 source distribution, but make fails with:
./Modules/signalmodule.c: In function ‘fill_siginfo’:
./Modules/signalmodule.c:745:60: error: ‘siginfo_t’ has no member
named ‘si_band’
PyStructSequence_SET_ITEM(result, 6, PyLong_FromLong(si->si_band));
^
Include/tupleobject.h:62:75: note: in definition of macro
‘PyTuple_SET_ITEM’
#define PyTuple_SET_ITEM(op, i, v) (((PyTupleObject
*)(op))->ob_item[i] = v)
^
./Modules/signalmodule.c:745:5: note: in expansion of macro
‘PyStructSequence_SET_ITEM’
PyStructSequence_SET_ITEM(result, 6, PyLong_FromLong(si->si_band));
^
NOTES:
* Google turned up several other reports of the same error message,
going back as far as python 2.6 for cygwin, but all the workarounds
seem to have been fixed in older versions upstream, and/or fix other
problems that had no obvious link with si_band (such as using
ncursesw instead of ncurses).
* I don't have (or know how to use) cygport, so maybe it would be as
simple as changing $VERSION in the .cygport file.
Detailed steps I followed:
Update: I installed cygport, waded through various slight
incompatibilities in the patches, and verified that the compilation
still fails with the same error message. The modified .cygport and
updated patches are attached (other patches remain the same as for 3.2).
The steps to repro are now simply:
# download the 3.3.2 source .xz from python.org
$ ./cygport --64 python3-3.cygport prep
$ ./cygport --64 python3-3.cygport compile
Going by this StackOverflow question, si_band is POSIX, though I don't
know which version introduced it... the linux man pages suggest
POSIX.1-2001. In any case, it looks like si_band is endemic in POSIX
systems, but missing in cygwin.
Updating the signal module to no longer expose si_band at all seems to
work around the problem (see patch), but compilation still dies (much
later) with:
