The rpm release of the compiler is designed to be installed on RedHat based distributions of Linux (e.g. RedHat, CentOS, Fedora, etc.) using the rpm tool set.

Installation:

$ sudo rpm --install sac2c-VERSION-RELEASE.rpm

The deb package is meant to be installed on Debian based distributions (e.g. Debian, Ubuntu, etc.) using the dpkg tool set.

Installation:

$ sudo dpkg --install sac-VERSION-RELEASE.deb

The pkg is an installer that will place the SaC files in the correct location on your system. Symbolic links to the SaC binaries are created in /usr/local/bin for your convenience.

The SaC binaries are postfixed by their release type (production or debug), so there is a sac2c_p and sac2c_d respectively, sac2c is simply a link to sac2c_p.

Installation:

1. Double click the downloaded pkg file
2. A dialog box should appear that will guide you through the install process
3. Confirm that you agree with our license, and click Install to install SaC
4. The binary sac2c_p should be in your PATH

The .tar.gz archive is intended for arbitrary installs, meaning that if you can't install sac2c using one of the other packages due to system permissions, you can use this archive to install it under you home-directory. The libraries of the compiler can be placed anywhere so long as the sac2c binary (and related) know where to find them. For this reason the archive provides the sac2c binary (and related) as source code to be compiled by the end-user.

For simplicities sake, an install script is provided. It supports several flags, but the most important one is -i to indicate where you want to install everything (for example ~/.local).

Installation of the compiler is as simple as extracting from the archive:

$ mkdir ~/temp_extract && cd ~/temp_extract
$ tar -xzf sac2c-VERSION-RELEASE.tar.gz
$ nano README                            # if you want more information on the install
$ bash ./install.sh -i INSTALL_DIR       # and thats it
$ cd ~ && rm -rf temp_extract
