PAKCS: The Portland Aachen Kiel Curry System

Installation Instructions

The current version of PAKCS runs on Unix-based platforms and has been tested under SunOS, Linux, and Mac OS X. If you want to install and run the complete system on your computer, you need the following software:

How to generate and install the PAKCS kernel:

  1. Go into the main directory of PAKCS (which contains this file). In the following, we assume that pakcshome is the name of this directory.
  2. Modify in the shell script "pakcshome/bin/.pakcs_variables" the definition of the variables JAVA and SICSTUS according to your local installation. If the variable SICSTUS is undefined, the Curry2Prolog compiler system is not installed (i.e., only the front-end is installed).
  3. If you prefer faster executables (but larger compilation times for Curry programs) with the Curry2Prolog compiler system, you can modify the definition of the variable FASTCODE in the file "pakcshome/curry2prolog/Makefile".
  4. Execute "make" which installs PAKCS as a saved state of Sicstus-Prolog (if you have already another installation of PAKCS, do "make clean" before).
  5. Add the directory "pakcshome/bin" to your path, e.g., by the command
    set path ($path pakcshome/bin)
    in the C-shell. Since pakcshome/bin/sicstus is equivalent to a call to your local Sicstus-Prolog system (as defined by the variable SICSTUS above), the shell command sicstus is now a call to your Sicstus-Prolog system. This is necessary to restore Sicstus-Prolog saved states correctly.
  6. Now you can start the Curry2Prolog compiler system via the commands "pakcs" or "curry2prolog" (and the TasteCurry interpreter via the command "tastecurry").
  7. If you want, you can also execute "make libdoc" to generate the online documentation of all system libraries by the CurryDoc tool into the directory "pakcshome/lib/CDOC".
  8. You can configure the behavior of PAKCS by various setting in a "pakcsrc" file. For doing so, copy the file pakcshome/pakcsrc as ".pakcsrc" into you home directory and modify the settings.

How to install additional packages:

The distribution of PAKCS contains various additional packages and libraries. Some require additional software packages that are described below.
  1. If you want to use the Tk library for GUI programming in Curry (pakcshome/lib/Tk.curry), you need also a Tcl/Tk implementation (including the windowing shell wish) which can be downloaded here. In this case, the windowing shell wish must be in your path (or you can also modify the definition of the function openWish in the Tk library pakcshome/lib/Tk.curry).
  2. If you want to use the DaVinci library for the visualization of graphs (pakcshome/lib/DaVinci.curry), you need also an installed daVinci system which can be downloaded here. In this case, you have to modify the definition of the constant dvHome in the library pakcshome/lib/DaVinci.curry according to the installation path of daVinci.
  3. If you want to use the compiler for Curry into Java (command "curry2java"), you need also a Pizza compiler and you have to modify the definition of the variable PIZZACLASSES in the shell script "pakcshome/bin/.pakcs_variables" according to your local installation of the Pizza compiler.
