Can't build xapian-bindings in a virtual env

[Eric Abrahamsen]

Hi,

I'm on a Ubuntu 18.04 server, trying to use django-haystack with xapian
in a python3.6 virtualenv.

The virtualenv is set up not to use system packages, meaning that I
can't just install python3-xapian-haystack with apt, and instead have to
manually build xapian-core and xapian-bindings within the virtualenv.

This works with xapian-core and the --prefix argument to configure. When
I try the same with xapian-bindings, using:

./configure --prefix=$venv --with-python3

The configure process looks fine: xapian-config is found correctly, as
is my virtualenv python installation. Then I export LD_LIBRARY_PATH as
$venv/lib. Then "make" fails with:

make  all-recursive

Can anyone tell me how to get this package configured and built
correctly?

Thanks!
