I was trying this example program out of a well known postgresql book and keep getting errors whenever I try to compile.

Error messages ##make client1


cc -g  client1.o  -L /usr/lib -L /usr/lib/pgsql -o client1
client1.o: In function `main':

collect2: ld returned 1 exit status
make: *** [client1] Error 1
---------------------------------------------------------

cc -g -I /usr/include -I /usr/include/pgsql -I /usr/include/pgsql/ server -c -o client1.o client1.c /root/PROGRAMMING/C_API/client1.c:10: undefined reference to `PQconnectdb' /root/PROGRAMMING/C_API/client1.c:11: undefined reference to `PQfinish'

you must add -lpq too your LDFLAGS
in order to link the lib you only have the linker paths set in LDFLAGS

it should read like this then:
cc -g  client1.o  -L /usr/lib -L /usr/lib/pgsql -o client1 -lpq
