Hi Dave,<div><br></div><div>Do you mean this fix that didn&#39;t work for you?</div><div><a href="https://github.com/pgRouting/pgrouting/issues/48">https://github.com/pgRouting/pgrouting/issues/48</a></div><div><br></div><div>

With Ubuntu 11.04 there was such an error as well, but that time this small fix was sufficient:</div><div><a href="https://github.com/pgRouting/pgrouting/commit/803092f4103f3ebd7420e598c5ab5231fe40def4">https://github.com/pgRouting/pgrouting/commit/803092f4103f3ebd7420e598c5ab5231fe40def4</a></div>

<br>
I am running Postgres 8.4.10 on  2.6.38-13-generic #54-Ubuntu,  I was<br>
having some issues with the pgr source code, so I down loaded it and<br>
attempted to build it.<br>
<br>
Everything seemed to go ok until I tried to use the driving distance code<br>
when I got the diagnostic<br>
<br>
psql:routing_dd.sql:28: ERROR: could not load library<br>
&quot;/usr/lib/postgresql/9.1/lib/librouting_dd.so&quot;:<br>
/usr/lib/postgresql/9.1/lib/librouting_dd.so: undefined symbol:<br>
__gmpq_equal<br>
<br>
I have tried the bug fix DD_routing and PostgreSQL 9.1, which seems to<br>
fixes other peoples problems with the same bug, but it does not work on my<br>
machine.<br>
<br>
Any suggestion as to what to do next?<br>
<br>
&gt;From what I have seen it looks like a version issue/relocation error.  I<br>
looked at most of the liabires with nm -C and can not find the &#39; missing<br>
library&#39;<br>
