Installation Instructions.

Bousi$\sim$Prolog version 1.04 (release April 2008) is available in two distribution formats: the executable distribution and the complete source code distribution.

The current version of the low level implementation of Bousi$\sim$Prolog runs on Unix-based platforms and has been tested under Linux (Red Hat/Fedora and Debian/Ubuntu distributions).

If you want to install the BPL system on your computer, starting from the complete source code distribution you need SWI-Prolog. Also, for compiling the source code, in order to generate an executable (state) file you may need the following packages installed on your computer:

• Red Hat/Fedora distributions: gmp-devel, ncurses-devel, readline-devel.
• Debian/Ubuntu distributions: libgmp3-dev, libncurses5-dev, libncursesw5-dev, libreadline5-dev.

On the other hand if you want to install and run the executable distribution, you do not need SWI-Prolog and, in order to run the executable (state) file you only may need the following packages installed on your computer:

• Red Hat/Fedora distributions: gmp, ncurses, readline.
• Debian/Ubuntu distributions: libgmp3c2, libncurses5, libncursesw5, libreadline5.

The following installation procedure is only for the executable distribution.

• Go into the directory where you want to download the executable distribution and download it.

• Decompress the file bousi-installer.tgz by the command:

                  tar -xzf bousi-installer.tgz
  

  Then, a subdirectory (called ``bousi-installer'') is created containing the files of the executable distribution.

• Go into the bousi-installer directory, launching the installation process by the command

                  . installer.sh
  

  Then, follow the installation instructions. If you are an ordinary user and you choose the default installation option, the executable file ``bousi'' and the shared library ``closure.so'' are installed into the directory $HOME/bousi-prolog. If you are root, the default directory where those files are installed is /usr/local/bousi-prolog.

• Once the installation is ended you can start the BPL system via the command ``bousi''.

WARNING: If you try to launch the BPL system by double clicking the executable file bousi from a file browser window, it might happen that the BPL system is not open but it remains resident in memory consuming a great amount of CPU resources. Always it is preferable to launch the BPL system from a (unix shell) terminal by means of the command ``bousi''.
