contrib - fuzzystrmatch installation issue
Kenaniah Cerny
I am running Postgres 8.3.3 on a CentOS box and I had a few issues when trying to install the fuzzystrmatch library. The library seemed to compile and make install correctly, but when I ran the sql scripts to add the functions to a database, I came up with this issue:
# psql -d template1 -U postgres -f fuzzystrmatch.sql
SET
CREATE FUNCTION
CREATE FUNCTION
CREATE FUNCTION
CREATE FUNCTION
psql:fuzzystrmatch.sql:24: ERROR: could not find function "difference" in file "/usr/lib/pgsql/fuzzystrmatch.so"
psql:fuzzystrmatch.sql:28: ERROR: could not find function "dmetaphone" in file "/usr/lib/pgsql/fuzzystrmatch.so"
psql:fuzzystrmatch.sql:32: ERROR: could not find function "dmetaphone_alt" in file "/usr/lib/pgsql/fuzzystrmatch.so"
Apparently, these three functions did not compile into the module. I'm not much of a C/C++ programmer, but according to the Makefile, both object files were included in the resulting fuzzystrmatch shared object, and the three functions in question where definitely present in fuzzystrmatch.c to begin with.
The following is a list of symbols inside the shared object:

The compiler didn't return any errors during the build process, leaving me clueless as to why it's not working correctly. Any help would be greatly appreciated.
Thanks,

I'm suspicious that /usr/lib/pgsql/fuzzystrmatch.so is actually the 7.4
version of that module (which is what shipped in RHEL4 to begin with,
and which would've lacked exactly those three functions). However a
hole in this theory is that an 8.3 server should've refused to load
a 7.4 extension module at all. Anyway, double check versions,
installation locations, etc. A self-configured Postgres installation
would not default to installing into /usr/lib/pgsql, so it certainly
seems possible that that file isn't your newly built version.
Another thing that seems pretty odd is that the above complains about
difference(), which *is* present in the .so according to nm.
BTW, why are you compiling fuzzystrmatch for yourself at all, instead
of just installing the postgresql-contrib RPM?

He had also written me directly off list -- version mismatch it was. See
below. I should have thought to copy the list on my reply -- sorry about
that.
