The pg gem is only a way to communicate with the Postgres server; make
sure you have postgresql and postgresql-dev installed on your system
(with Linux, there should be apt or rpm packages available; not sure
about Windows).

Re: pg gem error

On Ubuntu, there is one libpq-dev ( which you have installed ) and the
other is postgresql-server-dev-<version>. I think you need both.

Re: pg gem error

I am getting crazy about this problem... Basically pg compiles for my 
system ruby (installed via apt-get), also compiles for my RVM ruby 1.8 
BUT when I try to compile it for RVM ruby 1.9 it will fail!!! Why??


Error is always:
Can''t find the PostgreSQL client library (libpq)

Which 1.9?

Is it the same version of the pg gem that in the case that compiles
and the one that doesn''t?

Re: pg gem error

1.9.3, I fixed it...

I had to rename a "lib" folder inside the .rvm directory, compile the 
gem separately and then re-rename the folder...

Re: pg gem error

Instead of compiling it by hand, you specify the missing headers in the gem 
command:

rvmsudo gem install pg -- --with-pg-lib=/usr/pgsql/lib/ 
--with-pg-config=/usr/pgsql/bin/pg_config

If you need to bundle install pg (or other gem that uses it), you could use 
a bundle config file: 

bundle config build.pg --with-pg-lib=/usr/pgsql/lib/ 
--with-pg-config=/usr/pgsql/bin/pg_config

Re: pg gem error

My error wasn''t related to any missing headers, pg was being linked
with
the wrong libraries.
