Re: Statically linking against libpq

Hi,

Looks to me like you have to add -lkrb5 and -lssl to your compile flags
as well. Perhaps some more others (you can use nm in conjunction with
grep to find which libraries define the missing symbols (On OpenBSD
like so: 'cd /usr/lib && nm -o * | grep krb5_free_context' but that
might differ on Fedora Core 3).

Regards,
Daniel
