Chicken Scheme With the IUP Gui egg

Install:

1. Install the GNURoot Debian package from Google Play.
2. You will need to do:

   apt update
   apt upgrade
   apt install libreadline-dev libwebkitgtk-dev libwebkitgtk-3.0-dev libpangox-1.0-0 zlib1g-dev libfreetype6-dev cmake libssl-dev  uuid-dev cmake curl ruby wget libgl1-mesa-dev libglu1-mesa-dev libgtk2.0-dev lua5.3 liblua5.1-0-dev liblua5.3-dev libsqlite3-dev libpq-dev libgtk-3-dev libftgl-dev

   NOTE: Probably not all those packages are needed.
3. Get the files from http://www.kiatoa.com/cgi-bin/fossils/opensrc/uv/pkgs/chicken-iup-arm-rasbian-06-08-2018.tar.gz and untar into "/". NOTE: For GNURoot you'll need to install libpng16: http://www.kiatoa.com/cgi-bin/fossils/opensrc/uv/pkgs/libpng16-from-raspbian.tar.gz

   (cd /;tar xzf $PWD/chicken-iup-arm-rasbian-06-08-2018.tar.gz)
   (cd /;tar xzf $PWD/libpng16-from-raspbian.tar.gz)

4. To start up csi or compile code first source /opt/chicken/4.13.0/setup-chicken4x.sh

To build from source you can use the chicken-installall.sh script from http://www.kiatoa.com/cgi-bin/fossils/opensrc/dir?name=utils. I couldn't get it to work on GNURoot but you can build on Raspbian and copy the files to GNURoot.
