[rrd-users] Trouble installing rrdtools Ruby bindings on Mac

[Sanjit Jhala]

Hi,

I am trying to run the Ruby bindings on a Mac OSX 10.6.3. I installed
rrdtool 1.3.8 via macports. In addition I downloaded the source for
rrdtool-1.3.8, edited the dir_config in bindings/ruby/extconf.rb to:
dir_config("rrd","../../src","/opt/local/lib/"), and ran
"ruby extconf.db; make; sudo make install". However when I run my ruby code
I still get:
*
=> Booting Mongrel
=> Rails 2.3.7 application starting on http://0.0.0.0:3000
/Library/Ruby/Site/1.8/universal-darwin10.0/RRD.bundle:
dlopen(/Library/Ruby/Site/1.8/universal-darwin10.0/RRD.bundle, 9): Symbol
not found: _rrd_create (LoadError)
  Referenced from: /Library/Ruby/Site/1.8/universal-darwin10.0/RRD.bundle
  Expected in: flat namespace

    from
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in
`require'

*When I run "ruby extconf.rb" I get:
checking for rrd_create() in -lrrd... no

which seems like a bad thing.

Heres some more info about my machine and rrdtool/ruby binding install
procedure.

*I will try and install rrdtool directly from the source instead of macports
to see if that makes a difference, but other than that any help will be much
appreciated.
