title: How do I compile/build against Ocamlodbc
body: <p>I've installed Ocamlodbc using <code>opam install odbc</code>, but I can't work out how to build an app that uses it with ocamlbuild.  The examples that come with the source don't build either.</p>
  
  <p>If I put</p>
  
  <pre><code>#require "odbc";;
  </code></pre>
  
  <p>into my <code>.ocamlinit</code>, I can <code>open Odbc_unixodbc;;</code> in <strong>utop</strong>, but any reference to functions in that module result in a "Reference to undefined global 'Odbc_unixodbc'" error.</p>
  
  <p>The following snippet also fails with an error about no implementation for "Odbc_unixodbc"</p>
  
  <pre><code>open Odbc_unixodbc
  
  let () =   ignore (Odbc_unixodbc.connect "DSN" "UID" "PWD")
  </code></pre>
  
  <p>Trying</p>
  
  <pre><code>open Odbc
  </code></pre>
  
  <p>fails with "Unbound module Odbc"</p>
  
  <p>I'm building the code with</p>
  
  <pre><code>ocamlbuild -pkg odbc test.native
  </code></pre>
  
  <p>The generated documentation for the package seem to suggest I should be opening the "Ocamlodbc" module, but that also results in an "Unbound module" error.</p>
