I Need Help Getting a libpq Progam to Compile SCO

Hi,

I installed the skunkware 7.2.1 postgresql and I can not get a program
to compile using the libpq library. Please help if you can. Thanks.

I have the following installed:

PostgreSQL Data Base Management System (ver 7.2.1)
Readline (ver 2.1)
zlib - unencumbered lossless data-compression library (ver 1.1.4)

cc -g -v -Xa -a ods30 -b coff -K pentium -I/usr/include
-I/usr/local/pgsql/
include pgtest.c ./pgtest -L/usr/local/pgsql/lib -lpq
undefined first referenced
symbol in file
PQfinish pgtest.o
PQsetdbLogin pgtest.o
PQstatus pgtest.o
PQerrorMessage pgtest.o
PQexec pgtest.o
PQresultStatus pgtest.o
PQclear pgtest.o
PQnfields pgtest.o
PQfname pgtest.o
PQgetvalue pgtest.o
PQntuples pgtest.o
