Re: Typelib fails to compile using Ruby 1.9.2

Hi Ruben,
did you resolve this issue? After doing upgrade to Debian 7.2 with gcc 4.7 and ruby1.9.1
I get the same error. I have  2.6. toolchain with electric. Also GEM_HOME is pointing to .gem which is not existent.
With ruby1.8.6 the error is different



 rake setup[-DOROCOS_TARGET=]
  Using the crusty system installed rake... you probably want to upgrade
  WARN: cannot load RDoc, documentation generation disabled

    did you install Typelib's Ruby bindings and update the RUBYLIB environment variable accordingly ?
    did you add /home/azamat/programming/ros-electric/orocos_toolchain/orogen/lib to RUBYLIB ?

Sylvain, any idea?

Using Ruby 1.9.3 I get the following error:
