   I was able to build on kinetic using the last change in the indigo-devel branch. I am using ruby 2.4

   I then copied your sample publisher to src/rosruby, changed it to be executable, and ran it with rosrun rosruby publisher.rb.
   The failure is now this:

    rosrun rosruby publisher.rb
   /home/ubuntu/.rbenv/versions/2.4.1/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- gserver (LoadError)
   	from /home/ubuntu/.rbenv/versions/2.4.1/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require'
   	from /home/ubuntu/pincair/devel/.private/rosruby/lib/ruby/vendor_ruby/ros/tcpros/server.rb:8:in `<top (required)>'
   

   It seems that gserver is no longer part of ruby core, and is now a gem. (see similar issue).

   Do you have any suggestions on how to fix this? Is there anyplace I can specify a Gemfile?

   update. solved the gserver issue by copying the gserver code to the rosruby lib/ directory. Like so:

   curl -fsSL https://raw.githubusercontent.com/ruby/gserver/master/lib/gserver.rb > $HOME/<stuff>/rosruby/lib/gserver.rb

   hi, thank you for debugging. rosruby does not use gem in the core system now (using only for tests or docs). copying might become a quick fix. (I cannot replace it with other default ruby library, because i dont have enough time now.) Do you know the license of the gserver? Another possibility is using rosdep. It seems that it supports gem(i dont know the details). https://github.com/ros/rosdistro/blob/master/rosdep/ruby.yaml 2017/07/21 7:11 "Daniel Wiesmann" <notifications@github.com>:

   Hi @OTL, the license is the ruby license: https://github.com/ruby/gserver/blob/master/LICENSE.txt

   Here is the project repo: https://github.com/ruby/gserver
