Hi, I'm having problems using HDBC-postgresql (I've tried both 0.99.2.1 and 1.0.0.0) with postgresql (version 8.1.4, installed in /share/pgsql). I adjust the include-dir and extra-lib-dirs to use the custom location of postgresql, and build: no error messages, everything seems fine. However, when I then try to type: ghci -package HDBC -package HDBC-postgresql , I get the error message: Loading package HDBC-postgresql-0.99.2.1 ... linking ... ghc-6.4.2: /home/mpercossi/opt/lib/HDBC-postgresql-0.99.2.1/HSHDBC-postgresql-0.99.2.1.o: unknown symbol `PQserverVersion' ghc-6.4.2: unable to load package `HDBC-postgresql-0.99.2.1' Has anyone seen this error message before? Google didn't turn up anything relevant to haskell -- however there does seem to be a PQserverVersion procedure in the libpq library -- maybe HDBC-postgresql is not seeing this due to the custom install location? TIA Martin
