libpq compile error - Mailing list pgsql-general

Hello.

I try to compile the 1.1 example code which is shown at the page
http://postgresql.mirror.easynet.be/users-lounge/docs/7.1/programmer/libpq-e
xample.html.

I run OpenBSD 2.9 (i386) and I installed the 7.1 Postgresql client
interface.

I do this :


bash-2.04$
bash-2.04$
bash-2.04$
bash-2.04$ gcc -v -I/usr/local/include/postgresql/ -o testlibpq testlibpq.c
