Problems installing postgres in Ruby

Hi,

I got some problems getting the postgres installed in Ruby. This
is the output I get:

# gem install postgres
Building native extensions.  This could take a while...
ruby extconf.rb install postgres

make install
make: Nothing to be done for `install''.

make clean
Successfully installed postgres-0.7.1


It ends sucessfully so it looks ok except for the fact that make install
doesnt do anything.

But when I test it I get:
# ruby -e ''require "rubygems"; require_gem
"postgres";''
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'': no such file to load -- postgres (LoadError)
        from

        from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:229:in `activate''
        from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:228:in `activate''

        from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:59:in
`require_gem''
        from -e:1

Can anyone here help me out?

Torkel

have you considered using the "pure ruby" version?

gem install postgres-pr

Yes. I did try that earlier and I got that installed and working with 
the test from above.

However I did not get it to work from the program that I want this for 
so I don''t know if its supported. Is postgres and postgres-pr different
in any case or should both work from any program?

Its the new Metasploit I want to try if anyone got any more tips then.

I just had exactly the same problem installing the ruby-postgres-0.7.1 gem,
which I -believe- is the latest version of what used to just be called the
"postgres" gem.  It seemed to install, yet ''require
"postgres''" failed.

I''m using Postgres 8.1 on Ubuntu 6.06.  I''d previously used
Postgres 8.0 on
Mandrake 10 with no problems. 

Torkel, which Postgres and what OS?

Can anyone confirm my recollection that ruby-postgres is the rightful
descendant of postgres?  The postgres gem itself wouldn''t build on my
system, as it depends on libpq-fe.h which is apparently missing from 8.1
(or at least Ubuntu''s packaging of it).

Postgres 8.1.4-1 and Fedora Core 5

Did you do "gem install postgres" or "gem install
ruby-postgres" ?

I tried both.  "gem install postgres" failed to build the native
extension;
it depends on libpq-fe.h which is apparently gone in 8.1.  "gem install
ruby-postgres", which I believe is the updated replacement for the former,
appeared to succeed but then was still "missing". 

Maybe someone will have the answer...

Re: Problems installing postgres in Ruby

Looks like it gets installed, but not built on my FC5 setup:

How I got it to work:

gem install postgres
cd /usr/lib/ruby/gems/1.8/gems/postgres-0.7.1/
make

This fixed my install of ruby-postgres on Ubuntu Dapper as well.  The
extra make put files postgres.o and postgres.so into the
/usr/local/lib/site_ruby/gems/gems/ruby-postgres-0.7.1.2006.04.06
directory.
