Ruby Swig

Build system for Ruby + SWIG C libraries using CMake.

Requirements

• Ruby
• C compiler (C99-compatible)
• CMake >= 3.2
• Swig

Setup

Execute these commands in the root project directory.

# Install gems
$ gem install bundler
$ bundle install

# Install SWIG
$ sudo apt update
$ sudo apt install swig

# Compile components
$ mkdir build && cd build
$ cmake ..
$ cmake --build . --

# Run from project root directory
$ bundle exec bin/ruby_swig.rb
Hello World!

Tips

If the build fails with a NOTFOUND error, try adding the directory of ruby.h and ruby/config.h on your system to the find_path HINTS in CMakeLists.txt.

Unfortunately, there is no way to determine this automatically.

Try looking in ~/.rbenb/versions, ~/.rvm/rubies, /usr/local/lib/ruby, etc.
