How to build with Awestruct

On Fedora 31

Follow these instructions:

# Optional: clean your system first.
$ sudo dnf remove ruby rubygems rubygem-rake rubygem-bundler ruby-devel rpm-build gcc-c++ make

# Install ruby and other native RPM packages
# TODO Is rpm-build obsolete? It was once needed for ffi
# TODO Is gcc-c++ obsolete? It was needed for eventmachine
$ sudo dnf install ruby rubygems rubygem-rake rubygem-bundler ruby-devel rpm-build gcc-c++ make

$ ruby --version
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux]

# Setup the gem dependencies
$ rake setup

Then build the optaplanner-website (before and after your changes):

$ rake clean build
$ firefox _site/index.html

And publish your changes (if you got authorization, otherwise Jenkins will do it):

$ rake clean build publish

Troubleshooting:

• Error message Could not find ffi-1.13.1 in any of the sources

  If you get that error message, run:

  sudo gem pristine ffi --version 1.13.1
  ...
  rake setup

On other systems

Follow the instructions of Awestruct’s getting started guide.
