Alice ML is a functional programming language based on Standard ML, extended with rich support for concurrent, distributed, and constraint programming. Alice ML extends Standard ML with several new features:

• Futures: laziness and light-weight concurrency with implicit data-flow synchronisation
• Higher-order modules: higher-order functors and abstract signatures
• Packages: integrating static with dynamic typing and first class modules
• Pickling: higher-order type-safe, generic & platform-independent persistence
• Components: platform-independence and type-safe dynamic import & export of modules
• Distribution: type-safe cross-platform remote functions and network mobility
• Constraints: solving combinatorical problems using constraint propagation and programmable search

More about Alice ML is available from the original project page: http://www.ps.uni-saarland.de/alice/

The following packages were required to build on Ubuntu 19.10:

$ sudo apt-get install smlnj smlnj-runtime ml-lex ml-lpt ml-yacc     
$ sudo apt-get install g++ libsqlite3-dev libgtk2.0-dev libgmp-dev \
     gawk libtool libgnomecanvas2-dev gtk2-engines-pixbuf \
     libxml2-dev autoconf texinfo

To build:

$ git clone git://github.com/aliceml/aliceml
$ cd aliceml
$ git submodule init
$ git submodule update

$ cd make
$ make setup
#...add directory displayed to the PATH...
$ export PATH=/path/displayed/in/setup:$PATH
$ make all

The final system will be in the distro subdirectory and instructions are printed at the end of make all on how to add to the PATH and run.

Support for building on Mac OS X is in the early stages and slightly more manual than building on Linux due to errors I haven't worked out. Help from Mac OS X users would be useful.

The following packages were used from Homebrew:

$ brew install smlnj gmp libgnomecanvas gtk+ gawk

To build:

$ git clone git://github.com/aliceml/aliceml
$ cd aliceml/make
$ export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig:/usr/local/lib/pkgconfig
$ make setup
#...add directory displayed to the PATH...
$ export PATH=/path/displayed/in/setup:$PATH
$ make all

On my machine the make all fails some time in the build when compiling NativeLibs.cc with this error:

distro/bin/seamtool: line 63: echo: write error: Resource temporarily unavailable

The build can be continued with:

$ PATH=/path/to/aliceml/distro/bin:$PATH make -C ../alice/sources/lib/gtk/seam/
$ make all

The final system will be in the distro subdirectory and instructions are printed at the end of make all on how to add to the PATH and run.

This git repository was created by converting Gareth Smith's mercurial repositories to git with minor bitrot fixes. Instructions for building Gareth's original code is from a post on the Alice ML mailing list. Note that Gareth's repository contains many changes to the original Alice ML CVS repository but is the only one I've found buildable on modern Linux systems.

During the make setup process the source to gecode will be downloaded.
