[pgrouting-users] undefined symbol: __gmpq_equal

[Dave Potts]

Hi List

I am running Postgres 8.4.10 on  2.6.38-13-generic #54-Ubuntu,  I was
having some issues with the pgr source code, so I down loaded it and
attempted to build it.

Everything seemed to go ok until I tried to use the driving distance code
when I got the diagnostic

psql:routing_dd.sql:28: ERROR: could not load library
"/usr/lib/postgresql/9.1/lib/librouting_dd.so":
/usr/lib/postgresql/9.1/lib/librouting_dd.so: undefined symbol:
__gmpq_equal

I have tried the bug fix DD_routing and PostgreSQL 9.1, which seems to
fixes other peoples problems with the same bug, but it does not work on my
machine.

Any suggestion as to what to do next?

>From what I have seen it looks like a version issue/relocation error.  I
looked at most of the liabires with nm -C and can not find the ' missing
library'
