the sqlite3 gem uses a native C extension which needs to compiled for your system. (usually done when installed via rubygems)<br>The installation will fail if you use macgem, probably due to some IO issues and the lack of support of C extension.<br>
<br>Someone should look into writing a wrapper for macruby using an obj-c driver. That can&#39;t be that hard and that would be very useful. I&#39;ve been thinking about porting the DataObject and the DO SQlite3 driver to MacRuby but I didn&#39;t have time yet (and I didn&#39;t really need it either).  DataObject is the uniform API used by DataMapper to talk to its drivers.<br>
If someone is interested in working on that, I can put him/her in contact with the DM team.<br><br>- Matt<br><br><br><br><div class="gmail_quote">2009/3/31 Tim Rand <span dir="ltr">&lt;<a href="mailto:timrandg@gmail.com">timrandg@gmail.com</a>&gt;</span><br>
