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:
(in /usr/lib/ruby/gems/1.8/gems/ParseTree-1.6.0)
sh: line 1: RC_CFLAGS: command not found
/usr/bin/ld: Undefined symbols:
_rb_cObject
_rb_const_get_at
_rb_define_singleton_method
_rb_intern
collect2: ld returned 1 exit status
rake aborted!
error executing cc $(RC_CFLAGS) -bundle -g -Os -pipe -fno-common -pipe
-fno-common -pipe -fno-common -I /usr/lib/ruby/1.8/universal-darwin8.0
-o "/Users/Ken/.ruby_inline/Inline_ParseTree_dc10.bundle"
"/Users/Ken/.ruby_inline/Inline_ParseTree_dc10.c" : 256
Renamed /Users/Ken/.ruby_inline/Inline_ParseTree_dc10.c to
/Users/Ken/.ruby_inline/Inline_ParseTree_dc10.c.bad
/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.

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

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...
