Rcov problems

Hi everyone,

I’ve tried installing rcov for JRuby using 3 different options, but none
of them has worked:

  1. Installing rcov from Ruby Gems: ERROR: Failed to build gem native

  2. Installing hooligan495-rcov (from github): Same error.

  3. I tried building rcov-java from source, either without options
    (crashes) or with --without-ext. In the latter case gets installed but
    crashes when I call it:

The rcovrt extension I found was built for a different version of rcov.
The required ABI is: 2.0.0
Your current rcovrt extension is: 0.0.0

Anyone knows how to install it so it works?

Thanks in advance.
