Once Paragon is installed, here are the steps to compiling PrettyBook. Make sure you are in the Paragon directory you created. 1) Compile the Paragon source files, into Java files. $ ./parac -p libPI social/*.para Notice that this assumes that you are in the parent directory of "social", that there is a binary in the current directory called "parac" (the Paragon compiler), and a directory in the current directory called "libPI" (the Paragon interface files). 2) Compile the resulting Java files, with your Java compiler. $ javac -cp ".:paragon_rt.jar" social/Social.java Notice that this assumes that there is a JAR file in the current directory called "paragon_rt.jar" (the Paragon runtime). 3) Run the resulting compiled program, on your Java Virtual Machine. $ java -cp ".:paragon_rt.jar" social/Social Notice that this assumes that there is a JAR file in the current directory called "paragon_rt.jar" (the Paragon runtime).
