How to install a repository version of Isabelle. The following assumes that you have successfully checked out Isabelle from CVS into a directory $ISABELLE (by default 'isabelle') The directory structure of the repository is different from the distribution. The root directory $ISABELLE is the src subdirectory in the distribution. The 'normal' distribution directories are found in $ISABELLE/Distribution. To work directly on a working copy of the repository, do the following: Change directory to "$ISABELLE/Distribution/bin" and execute: ./isatool install -p ~/bin This will install Isabelle executables in ~/bin. Then issue in directory "$ISABELLE/Distribution" ln -s .. src This tells the Isabelle binaries where to find the theories. In $ISABELLE/Distribution/ install PolyML and ProofGeneral. If you have already installed them elsewhere, it is sufficient to create a symbolic link in contrib to the main PolyML and ProofGeneral directories. The links should be called 'polyml' and 'ProofGeneral'. Before you can build logic images it is necessary to initialise generation of browser info. Change to the directory "$ISABELLE/Distribution/lib/browser" and issue make Java JDK 1.1 or greater needs to be installed for this to work. Now you can build images by going to corresponding folders and issuing: isatool make (for instance, in "$ISABELLE/HOL" in order to make HOL). This will create the directory "~/isabelle" (if not already present). After setting up the local copy of Isabelle, changes in the repository can be imported by: cvs update -d -P (-d causes cvs to create directories that have appeared in the repository since the last update, -P causes directories that have been removed from the repository to be pruned). Internal environment variables $ISABELLE_HOME is the directory "isabelle/Distribution" from above. $ISABELLE_HOME_USER is the directory "~/isabelle". $Id$
