libpq interface problem.

Hi All,

I have a version of SCO Openserver 5.0.5 installed.
I downloaded and installed the postgresql-7.2-VOLS.tar file from
www.caldera.com/skunkware (the openserver packages option)
I also had to download and install the zlib-1.1.4-VOLS.tar file as the
postgresql server would not initialise without the libz.so file.

Once all this was installed I created a database and everything seems to be
working fine.

I am now trying to write a 'C' interface against the database using libpq.
I have included the libpg-fe.h file in the 'C' code and have had some
troublesome results :
(I have called my program test.c).

If I type 
cc -c -I/usr/local/pgsql/include test.c
the compiler creates a test.o file.
If I type 
cc -o test test.o -L/usr/local/pgsql/lib -lpq
I get the following error messages :
undefined                       first referencedsymbol                             in file
PQconnectdb                         test.o
PQstatus                            test.o
PQerrorMessage                      test.o
PQexec                              test.o
PQgetvalue                          test.o
PQntuples                           test.o
PQclear                             test.o
PQfinish                            test.o
i386ld fatal: Symbol referencing errors. No output written to test

So, I tried to get clever and downloaded the gcc-2.95.2pl1-VOLS.tar binary
file and installed it.
Now if I type
/usr/local/bin/gcc -c -I/usr/local/pgsql/include test.c
the GNU compiler creates a test.o file.
If I type
/usr/local/bin/gcc -o test test.o -L/usr/local/pgsql/lib -lpq
I get the following error messages :
Undefined                       first referencedsymbol                             in file

If anybody has any ideas as to how I can get around this problem (and
possibly explain what I am doing wrong) it would be much appreciated.

If I have not directed this question to the correct forum, could you please
let me know who to send it to ?
Kind Regards
