The ALS Prolog source tree is divided into core and peripheral directories. The core directory contains the source for the Prolog compiler, runtime, and IDE. The peripheral directories contain manuals, examples, extensions, etc. The tree is hosted on GitHub at:
https://github.com/AppliedLogicSystems/ALSProlog
Use git clone https://github.com/AppliedLogicSystems/ALSProlog.git to obtain the tree.
Linux, Unix-like systems, including Mac OS X and Cygwin:
Locate yourself in the toplevel 'unix' directory in the tree, and execute 'make'. When the build completes, you will find a folder
unix/linux/als-prolog
or
unix/darwin/als-prolog
or
unix/cygwin/als-prolog
or possibly
unix/<flavor>/als-prolog
where darwin is the Mac OS X flavor of Unix, and <flavor> is possibly some other flavor of unix detected by the build process.
Windows:
Locate yourself in the toplevel 'win32' directory in the tree, and execute 'make'. When the build completes, you will find a folder
win32/als-prolog
Generally, a GNU/Linux OS with standard build tools (Make, GCC with 32-bit support), Git, Ruby, Libcurl, and Tcl/Tk. Packages for popular distributions:
Debian/Ubuntu: sudo dpkg --add-architecture i386 && sudo apt-get update && sudo apt-get install build-essential git gcc-multilib ruby ruby-dev php libcurl4-openssl-dev:i386 tk-dev:i386
CentOS/Fedora: sudo yum groupinstall 'Development Tools' && sudo yum install ruby ruby-dev php glibc-devel.i686 libgcc.i686 libcurl.i686 tcl-devel.i686 tcl.i686 tk-devel.i686 tk.686
Xcode command line tools. For version before High Sierra (10.13), a recent version of Ruby is required. Homebrew Ruby is recommended.
MSYS2 tool-chain is used to build for Win32, with packages:
pacman --sync git base-devel mingw-w64-i686-toolchain mingw-w64-i686-curl zip procps
Ruby installed via RubyInstaller (use recommended Ruby+DevKit version).
PHP installed via PHP Download or elsewhere.
