ParseTree and OS X/other newbie OS X questions

[Kenneth McDonald]

Couple of questions from a newbie on OS X (intel PB Pro)...

First, ParseTree doesn't want to install do to compilation issues...

mbp:/usr/lib/ruby/gems/1.8/gems/ParseTree-1.6.0 Ken$ sudo rake install
Password:

/usr/lib/ruby/gems/1.8/gems/ParseTree-1.6.0/rakefile:7
(See full trace by running task with --trace)

...perhaps I need to do further ruby setup?


Also, I first installed ParseTree using 'sudo gem install ParseTree' but
I didn't get any messages to the effect that that had even tried a
compile--certainly not any error message. Is gem install supposed to
compile C extensions when it install something?

Finally, given that OS X is a bit of an odd bird, is there anything else
I need to do to make sure installs work smoothly in the future?

Thanks,
Ken

You don't want to run this from the gem. You'll end up installing a
version that overrides the gem version, so you won't get future updates.

Apple's ruby has a broken rbconfig.rb. Using a Ruby built from
source will work.

Also, I first installed ParseTree using 'sudo gem install
ParseTree' but I didn't get any messages to the effect that that
had even tried a compile--certainly not any error message. Is gem
install supposed to compile C extensions when it install something?

ParseTree uses RubyInline so it is compiled at runtime if it hasn't
been compiled before.

Finally, given that OS X is a bit of an odd bird, is there anything
else I need to do to make sure installs work smoothly in the future?

Its best to install a newer ruby from source instead of using the
built-in version.

Install from source worked. Thanks! Wish Apple would get their act
together on this stuff...
