octave-3.8.1 compatibility

Not compatible with octave-3.8.1

[averissimo]

what does not work for you?

I had a problem installing the gem against 3.8.1 with libcruft. But I've build octave-3.6.x from source and linked the libcruft.so* that is generated.

All functionality that I've tried so far is working (but haven't tested it extensively)

Same problem here. According to the changelog for the Ubuntu Trusty release (14.04), libcruft was removed from the package because it no longer exists upstream:

octave (3.8.0~rc1-1) experimental; urgency=medium [ Sébastien Villemot ] ... * Bump SONAME of library package to liboctave2. Also stop distributing libcruft, which no longer exists.

Building the gem from source works fine -- no need to rebuild Octave (QUITE the headache). Remove the libcruft dependency from ext/octave_api/extconf.rb and run

     ruby setup.rb config -- --with-octave-include=/usr/include/octave-3.8.1/octave 
     ruby setup.rb setup
     ruby setup.rb install

So it works, yes, but it would be nice to be able to just 'gem install octave-ruby'. I can't distribute anything I build on top of octave-ruby to less technical end users. Not when a download-modify-and-build is required.

UPDATE: almost works. In fact, starting the engine causes Ruby to crash on exit:
