问题
I am trying to install SciRuby on my Ubuntu 14.04 machine but installation failed. I also have an open github issue issue but had no success in installation process. By looking at the errors I am sure there some C/C++ compilation problem. Any help would be appreciated

It seems sciruby-full needs lots of native libraries. Run the steps..
RUN apt-get update
RUN apt-get install -y build-essential python3 python3-dev python3-pip ruby ruby-dev libzmq3 libzmq3-dev gnuplot-nox libgsl0-dev libtool autoconf automake zlib1g-dev libsqlite3-dev libmagick++-dev imagemagick libatlas-base-dev
RUN apt-get clean &&
ln -s /usr/bin/libtoolize /usr/bin/libtool
RUN pip3 install "ipython[notebook]"
RUN gem install --no-rdoc --no-ri sciruby-full && iruby register
