[postgis-users] Compiliing PostGIS vs PostgresSQL

[Darren Houston]

Sorry everyone. I e-mailed these instructions many hours ago, but only to
myself, so I thought it was from the Users' list when the message showed in
my inbox.

Here are my instructions for installing PostGIS with the default PostgreSQL
from RPM and/or fresh Linux operating system install. 

You should already have a PostgreSQL directory structure such as this in
your system;

/usr/include/pgsql 

/usr/share/pgsql 

/usr/lib/pgsql 

/var/lib/pgsql 

Now, you can install PostGIS into these directories or you can mimic a
PostgreSQL install in another directory such as /usr/local/pgsql. I like to
install PostGIS alone in /usr/local/pgsql to make it easier for updates.
I'll give instructions for both methods. Make sure PostgreSQL is shut down
(no postmaster process running).

For PostGIS installation into /usr/local/pgsql; 

1) Download postgresql-7.X.X.tar.gz, un-zip and un-tar (match the current
version of PostgreSQL installed on your system). 

2) Run the configure script with --prefix=/usr/local/pgsql and then run
make. You don't need to run make install.

3) Create these directories manually; 

   /usr/local/pgsql/bin 
   /usr/local/pgsql/doc 
   /usr/local/pgsql/include 
   /usr/local/pgsql/lib 
   /usr/local/pgsql/man 
   /usr/local/pgsql/share 

4) Install PostGIS as per Refractions instructions. 

You will notice PostGIS sitting in the directories in /usr/local/pgsql. I
like to enter each directory and copy the PostGIS files to a folder in that
directory stipulating PostGIS's version. This is how I keep multiple PostGIS
versions on my system.

For PostGIS installation into default RedHat (and other Linux versions)
PostgreSQL install; 

1) Move the following directories to *.bak (or some other name) 

   mv /usr/include/pgsql /usr/include/pgsql.bak 
      /usr/share/pgsql 
      /usr/lib/pgsql 
      /var/lib/pgsql 

You have to move the directories because PostgreSQL will see those
directories and then configure itself to install to /*/*/postgres instead of
/*/*/pgsql.

2) Download postgresql-7.X.X.tar.gz, un-zip and un-tar (match the current
version of PostgreSQL installed on your system). 

3) Run the configure script with --prefix=/usr and then run make. You don't
need to run make install. 

4) Move the previous directories to their original names 

   mv /usr/include/pgsql.bak /usr/include/pgsql 

5) Install PostGIS as per Refractions instructions. 

Hope this has enough info. E-mail me if you get in a bind and I'll help you
out.
