Installing and running Lucid Synchrone (Lucy)

lucy.sh

#!/bin/sh -eu

# The version of Lucid Synchrone / Lucy on the website was built a long time ago, and only has bytecode available.
# It seems that between ocaml 4.00.1 and 4.00.2, the bytecode format changed,
# so you need to use that version.
# This should:
#  install the right version of the compiler (assuming you have opam);
#  download lucy;
#  change the shebang of the binaries to point to the right version;
#  and put lucyc in /usr/local/bin.

# Try to install the 'right' version of OCaml
opam switch set 4.00.1

# Download and unpack lucy
wget http://www.di.ens.fr/~pouzet/lucid-synchrone/lucid-synchrone-3.0b.byte.tar.gz
tar -xvzf lucid-synchrone-3.0b.byte.tar.gz

# Hacky substitute into the shebang of the binaries
WHICH=`which ocamlrun`
perl -pi -e "s,/usr/local/bin/ocamlrun,$WHICH," lucy/bin/lucyc lucy/bin/lucys

# The makefile will now put lucyc in /usr/local
make -C lucy

# Set lib directory
