I am trying to use Ruby on Windows to perform some low level packet sniffing and manipulation. I have looked at pcaprub and can’t seem to get it compiled on Windows using Cygwin or Devkit. I am open to using other libraries if there is something I am not considering. What is the best approach here? Thanks, Chris ---

When you mention “devkit” I suppose you’re using RubyInstaller + DevKit, correct? If so I would suggest you provide the headers and development dependencies (lib) required for pcaprub be installed. Most of the time, the answers to these questions are in the documentation (if present) or the tool source code. Look into that and provide the full output of errors you’re getting; that helps too.
