Good day!
I have problems installing postgres gem.
It seems that gem cannot find my PostgreSQL installation.
Please tell me what options can I give to gem. Gem manual doesn't help.

I'm getting the following:

ERROR:  While executing gem ... (Gem::Installer::ExtensionBuildError)
     ERROR: Failed to build gem native extension.

ruby extconf.rb install postgres

i usually install this from source (not as a gem) - this way i can
specify where the postgresql header files and libraries live (i usually
also build the postgresql from source).

just download the source from http://ruby.scripting.ca/postgres/ and
follow the instructions in README file.

hope this helps,

vlad

Hm, seems like it's not finding the PostgreSQL header and object files.
You can probably get it to work by moving into that directory
(/usr/local/lib/ruby/gems/1.8/gems/postgres-0.7.1) and running:

ruby extconf.rb --with-pgsql-include-dir=/path/to/pgsql/headers
--with-pgsql-lib-dir=/path/to/pgsql/shared_libs

and then run "make" and "make install".

Yours,

Tom

You can also achieve the same thing in one step with gem by passing
the extconf args after '--':

  gem install postgres -- --with-pgsql-include-dir=...

Super!  The same thing happened to me with the MySQL gem yesterday, so
it's fresh in my mind...
