<div>I have upgraded the libdbi to the latest, compiled from source and the message seems to have gone away. Now syslog-ng loads up fine but doesn&#39;t seem to be writing anything to the database!

&gt; So far so good, but when I try to run syslog-ng it gives me an error:<br>

</div>                                    ^^^^^^^^^^^^^^^<br>
<br>
The problem lies here: while the module has been compiled, the DBI<br>
version is probably not fresh enough. I&#39;d suggest compiling libdbi from<br>
CVS.<br></blockquote></div><div><br>Perhaps not necessarily from CVS, but do make sure you also compiled the dbi-drivers.<br><br>I suspect there might be problems with the afsql not linking/loading libdbi (or it&#39;s mysql driver from dbi-drivers)<br>



<br>I&#39;m a low level debugger, so running strace on syslog-ng and posting that would be interesting to confirm/deny my hypothesis.<br><br></div></div>
