Re: New User: PostgreSQL Setup - "The Program 'postgress' is needed by initdb but was not found in the same directory..."

LXCcontainer - I'm not sure if this is contributing to my problem or not, but it's worth mentioning.  The main OS
(host)of my machine is  Ubuntu 11.10 (mostly, some packages are updated to newer versions), and my guest OS (inside the
container)is Debian.  I compiled PostgreSQL from source, and installed it inside the container.  However, I did have to
usethe "without zlib" and "without readline" options to compile.  This is strange, as both libraries are installed
(confirmedvia aptitude).   

The development packages for them may not be installed - zlib1g-dev and libreadline-dev - without those, you can't
buildapplications against those libraries.

This line suggests that your environment is broken - the chroot container hasn't been set up fully.

This isn't good, either. I'm suspicious of your lxc chroot.

This suggests that your build broke. Is there a /usr/local/pgsql/bin/postgres binary?

appreciated. I was hoping PostgreSQL would be reasonably straightforward to install.  So far I've tried the Ubuntu
tutorials,as well as one or two others online.  Now I'm installing from source and using a mailing list....so much for
simplicity.

LXC is definitely part of your problem - it sounds like your chroot isn't being set up correctly.

Once that's fixed, you'd still be better installing postgresql from apt. If, for some reason, you need to build it from
sourceI'd suggest building it on your host (Ubuntu) first, so you can see what a build looks like on a working platform
beforetrying to build it in the lxc chroot. 


>>>Thanks for the reply.  I actually tried installing via apt before building from source, and I got the same results
thatI have now.  I'm a bit confused, as the container appears to work correctly.  I set it up a template using
debootstrap,and have been copying that template container (and editing the necessary files, like
/etc/network/interfacesand such).  On of my containers runs an email server (Dovecot and Postfix), and everything
appearsto work fine there. 

I'll try installing PG on the host side (Ubuntu) and see what I get.  Also, I'll probably send out an email to the LXC
mailinglist and see what they think.
