Hi, Wojtek

Maybe you need to install postgresql93-devel package?

Hi.

I'm not sure if I should write here, or on a Centos mailing list...

I have fresh, vanilla Centos 6.5 with postgresql yum repository added.

I've successfully installed postgresql93 and postgresql93-libs packages, but still :

$ ld -lpq
ld: cannot find -lpq

$ ldconfig -p
        libpq.so.5 (libc6,x86-64) => /usr/pgsql-9.3/lib/libpq.so.5
        libpq.so (libc6,x86-64) => /usr/pgsql-9.3/lib/libpq.so

What did I do wrong?

They put the postgres stuff in versioned directories.
there is a program you use to find out where stuff is.
do a man on pg_config

$ pg_config --bindir
/usr/pgsql-9.3/bin

$ pg_config

So, it seems "ldconfig" searches in ld.so.conf.d paths, but "ld" doesn't...
which doesn't make sense to me.
