Ruby Forum Ruby on Rails > Connecting to MS SQL from Snow Leopard

Has anyone been able to get Rails talking to Microsoft SQL Server from
OSX Snow Leopard?  In the past with Leopard, I used the instructions
found here: http://wiki.rubyonrails.org/database-support/ms-sql.  But
with Snow Leopard I get the following error when I try to access an
ActiveRecord object:

/usr/local/lib/ruby/gems/1.8/gems/dbd-odbc-0.2.4/lib/dbd/odbc/
statement.rb:41: [BUG] Segmentation fault
ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10.0.0]

Any help is appreciated!

Thanks,
Tom

If switching to the unixODBC is an option for you, you may try the 
following.

- Install unixODBC.
  Download it from "http://www.unixodbc.org/" and configure it something 
like,
  "./configure --prefix=/usr/local/unixODBC-2.2.14 --enable-gui=no".

- Install freeTDS with
  "./configure --prefix=/usr/local/freetds-0.82 
--with-unixodbc=/usr/local/unixODBC-2.2.14".

- Configure /usr/local/unixOBCD-2.2.14/etc/odbc.init and odbcinst.ini

- Download ruby-odbc-0.9997 from "http://www.ch-werner.de/rubyodbc/",
  create the Makefile with
  "ruby extconf.rb --with-odbc-lib=/usr/local/unixODBC-2.2.14/lib", and 
install

Hope it helps.

Have you gotten unixODBC to work on Snow Leopard?

I wonder if you seeing a similar issue as with MySQL. Maybe you need to 
force the C extensions for your gems to compile for your specific 
platform using ARCHFLAGS:

Example:
sudo env ARCHFLAGS="-arch x86_64" gem install <gem_name> <options>

Make sure the -arch setting is correct for your platform.
One of [ i386 (32-bit), x86_64(64-bit), ppc, ppc64 ].

This is only a guess as to the cause of your problem, but maybe 
something you might want to look into.

Yes, it worked for me.

Is there a way to use unixODBC without a DSN?

I'm having the same problem as Tom. I can connect to the SQL Server
and run a "select *" from iSQL, so I believe that ruby-odbc bindings
are using iODBC instead of unixODBC

I was having this same problem.

I switched from iODBC to UNIXODBC and this problem went away for me!

Thanks for your help!

Can you post how you set up unixodbc to resolve the issue?

I would defer to the SQL Server adapter wiki for latest information.
