Compiling PHP Bindings


Hi all.

I have problem compiling xapian php bindings.

I am using debian sarge.

I have installed php4-dev before compilation.
I am getting the following errors:

That's most likely a GCC bug.  You shouldn't be able to cause an
"internal compiler error" (or ICE) even if you feed in gibberish.  The
other possibility is bad hardware ("Segmentation fault" is signal number
11):

http://www.bitwizard.nl/sig11/

If it's a hardware fault, it's unlikely to not be totally repeatable
(see that link for more details).

If it's a GCC bug, it's likely to be an optimisation problem (ICEs
usually are in my experience), so you can probably work around it by
turning down the optimisation level.

Re: Compiling PHP Bindings

Quoting Olly Betts <olly <at> survex.com>:

It looks like I have a hardware issue on this computer.

I had no problems compiling the application on other box using
debian sarge.

Need Help


I have to use Quartz as a backend in my project ...
I just tried to compile few .cc files ... It showed too many 
dependencies ...

Can anyone suggest me the best way to go through ??

Well, quartz isn't designed as a separate component which can just be
lifted out and used elsewhere.  You'd have to take the supporting
files too, or eliminate the need for them.  These aren't in the quartz
directory because they're shared with other parts of the library.

> Can anyone suggest me the best way to go through ??

I'd recommend using Xapian through the public API.  Internal APIs may
change from under you.

If that's not a feasible option, perhaps you should explain why...

Cheers,

Python 2.1 bindings

I'm having a problem compiling the python 2.1 packages for release 0.9.1
- I get many errors along the lines of:

../../python/olde/xapian_wrap.cc: In function `PyObject*
   PySwigObject_repr(PySwigObject*)':
../../python/olde/xapian_wrap.cc:664: error: `PyString_FromFormat'
undeclared
   (first use this function)

On further investigation, the copies of xapian_wrap.cc in the olde and
modern subdirectories of the python binding sources are identical.  I
suspect that something has gone wrong with the source code generation...

For now, I'm disabling python2.1 from the debian packages so that I can
get them built.

No, I think that's correct.  It's only xapian.py which is different
between "olde" and "modern".  However that's not a documented feature
of the swig/python -modern switch as far as I could see, so I took the
cautious approach and included both in case a newer swig release starts
producing different .cc and .h files with -modern.

The files are carefully listed in python/Makefile.am such that the
probably identical files go in the tarball next to each other, so when
they're duplicates, gzip should compress them to almost nothing.

Sigh.  It looks like this was probably broken by moving from SWIG 1.3.23
to SWIG 1.3.24.  The latter generates calls to PyString_FromFormat which
was added in Python 2.2.  There are some other Python 2.2 assumptions
