Re: : Errors when compiling with Postgres 7.2.3 Libraries on RedHat 8 - Mailing list pgsql-general

Hi,


I just checked my 7.2.2-installation. It looks like libpq++ is not compiled in
by default. Maybe your rpms don't have them. Check "rpm -ql
postgresql-lib|grep libpq++". It should print out the location of your
libpq++.so.
