[Xapian-discuss] Problem Installing Ruby Bindings

[Olly Betts]

I should probably warn that I'm no Ruby expert, and know nothing about
Rails at all.

Did you do step 5?  That looks like how Ruby gets told where to find
the xapian bindings (I don't see LD_LIBRARY PATH mentioned at all).

The installation instructions for xapian-bindings say:

    And then you'll need to tell Ruby to look for modules in this directory:

	ruby -I$HOME/my_ruby_modules myscript.rb

http://trac.xapian.org/browser/trunk/xapian-bindings/INSTALL 

If that works, I guess LD_LIBRARY_PATH isn't set correctly, or isn't
being used (is your ruby binary setuid perhaps?)

You could use strace (or similar, depending on OS) to find out what
files dlopen() tries to open.

If that doesn't find the issue, perhaps try asking the blog's author, or
if that doesn't help the acts_as_xapian mailing list might be a better
place to ask - I'd guess there's more Ruby expertise there:
