Chicken Scheme With the IUP Gui egg
Install:
# Install the GNURoot Debian package from Google Play.
# Get the unversioned files and untar in /. [http://www.kiatoa.com/cgi-bin/fossils/opensrc/uv/pkgs/chicken-iup-arm-rasbian-06-08-2018.tar.gz]. NOTE: For GNURoot you'll need to install libpng16: [http://www.kiatoa.com/cgi-bin/fossils/opensrc/uv/pkgs/libpng16-from-raspbian.tar.gz]
# 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.
