Hi,<br><br><div class="gmail_quote">On Thu, Apr 15, 2010 at 14:40, Johannes Waldmann <span dir="ltr">&lt;<a href="mailto:waldmann@imn.htwk-leipzig.de">waldmann@imn.htwk-leipzig.de</a>&gt;</span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

What happened was this:<br>
<br>
1. add some modules to a library (but forget to mention them in the cabal file),<br>
   then (in the lib source dir, without cleaning/reconfiguring)<br>
   &quot;cabal install --global&quot; (runs without complaint)<br>
<br>
2. re-compile an application that uses the library<br>
   (cabal configure &amp;&amp; cabal build): this gave &quot;undefined symbol&quot; errors<br>
   (for things from the added modules)<br></blockquote><div><br>Just to say that this has happened to me very often as well, on Windows. The first time it took me quite some time to realize what was going wrong...<br><br>

<br>Cheers,<br>Pedro<br></div></div><br>
