Can't link to libpq

От

Дата:
I have started at the beginning of the PostSQL Programmer's Guide and have typed in part of example 1.1 on page 23.
 
I have followed the instructions in section 1.12 for building the program.
 
The program compiles cleanly using the instructions in the manual :
    cc -I/usr/local/pgsql/include jim.c
 
I then compile it with the instruction
    cc -o jim jim.o -L/usr/local/pgsql/lib -lpq
 
However, I get the following errors:
 
Undefined symbol
PQfinish
PQsetdbLogin
pqstatus
fprint
PQerrorMessage
 
The manual says this occurs if I forgot the -lpq option, which I have not done.
 
I am using SCO Unix.
 
Can anyone help me?
