Embedding Ruby Interpreter + RUBYGEMS

  1. Hello everybody,

    I'm currently writing a c++ library, in which i need to embedded a ruby
    interpreter for calling the Ruby API.

    I've read already some interesting topics about this issue and already
    got a working setup for my interpreter.

    Unfortanetely i need also access to all gems provided by rubygems and
    that is currently failing everytime.


    # is always working

    # will results always result in the LoadError: "no such file to load -

    it seems rubygems can't expand completely the loadpath with all
    necessary gems and the embedded ruby interpreter can't find the

    "undefined reference to `Init_prelude' " (libruby1.8 is linked to my

    I guess, i should also mention, that i need to store all gems into
    another location and set up the environment variables GEM_HOME and

    require "facets" via irb is working.

    Does anyone know a fix workaround about this problem?

    I'm using Ruby 1.8.7 on Ubuntu 10.04 - 64Bit.
