[Pgpool-general] The "libpq is not installed or libpq is old" problem again

[David Andersen]

Hi,

This is my first mail, so I hope I am doing this right. I am a complete
linux novice and I have spent close to 6 hours with this problem and read
the posts at for example:
http://pgfoundry.org/pipermail/pgpool-general/2006-October/000482.html

I am trying to write install pgpool-II and I am trying to do the ./configure
step, but i just keep getting "configure: error: libpq is not installed or
libpq is old".

I have PostgreSQL 8.2.3 installed (I am actually using the EC2 image
described here:
http://developer.amazonwebservices.com/connect/entry.jspa?categoryID=101&externalID=869

I ran a locate libpq as this is my best guess of finding its path:

I then tried to run the following commands:
./configure --with-pgsql=/home/journyx/jt/pd/Linux/pgres/include/libpq/
./configure
--with-pgsql=/home/journyx/jt/pd/Linux/pgres/include/postgresql/internal/
./configure
--with-pgsql=/home/journyx/jt/pd/Linux/pgres/include/postgresql/internal/libpq/
./configure --with-pgsql=/home/journyx/jt/pd/Linux/pgres/include/
./configure --with-pgsql=/home/journyx/jt/pd/Linux/pgres/lib/
./configure --with-pgsql=/usr/lib/

All resulting in the same error message. I also tried various other
parameters without success. My next steps from now would be to use the most
popular tool in any novice's toolbox: To do random stuff.

If you would like access to the linux box itself I can send you the login
information.

David
