Xapian discuss - Sep 2005 - Mac OS X building...

This is a short tip for anyone having problems building the Python  
bindings for Xapian 0.9.2 on Mac OS X (and maybe a bug report for the  
maintainers of the python bindings).  I'm not sure if this is  
happening to anyone else, but the bindings weren't building for me  
properly.  "ld"  was reporting that it couldn't find some Python  
symbols like "_PyArg_ParseTuple" and others when attempting to link  
something.

In order to get the bindings to build on Mac OS, I had to change the  
configure script in the xapian-bindings source, replacing all  
occurrences of "-bundle" with "-bundle -undefined
dynamic_lookup".
Then, in the "make" step, I needed to ensure that the environment  
variable "MACOSX_DEPLOYMENT_TARGET" was set to "10.3".

This boils down basically to:

$ sed -e "s/-bundle/-bundle -undefined dynamic_lookup/g" -i bak  
configure
$ ./configure {opts...}
$ MACOSX_DEPLOYMENT_TARGET=10.3 make

I am running Tiger, FWIW.

I believe that only this last step is needed, i.e.:
> $ MACOSX_DEPLOYMENT_TARGET=10.3 make
If you do this, libtool should pass "-undefined dynamic_lookup"
automatically.

See previous discussion:

http://thread.gmane.org/gmane.comp.search.xapian.devel/558

It's unclear to me if xapian should force this to be set always, or if
we detect 10.3 or newer, or what.  The environment variable name
suggests that it depends what platform the code is to be deployed on
but it may be poorly named...

Any further insight would be welcome.  Otherwise all I can safely do
is to document the need to set MACOSX_DEPLOYMENT_TARGET in future
releases.
