This is the most recent tarball, which is effectively a snapshot of
the sources as of the time at which that set of Unix VMs was built.

The sources consist of the platform support code along with the code
that is directly generated from Smalltalk. The platform sources are
http://squeakvm.org/svn/squeak/trunk and the Smalltalk code is in
Monticello files "VMMaker-xxx.yyy" in the
http://source.squeak.org/VMMakerrepository.
The Cog VM is a branch with platform sources in
http://squeakvm.org/svn/squeak/branches/Cogand Smalltalk code "VMMaker.oscog-xxx.yyy" in the
http://source.squeak.org/VMMaker repository.
See Eliot's page at
http://www.mirandabanda.org/cogblog/ for information.
A number of related VM projects are under active development, including
git based repositories, automated cross-platform builds, and VMs custom
adapted to support specific projects (e.g. Pharo), and new Android VM
development. For build procedures, see package CMakeVMMaker in the
source.squeak.org/VMMaker repository. The Subversion trunk and
branches/Cog repositories contain build procedures and documentation
from their respective authors, including the original cmake build
system currently in use with Ian's unix trunk VMs.
The Jenkins server and git mirror repository with CMakeVMMaker
are supported by the Pharo project, and you can find many instructional
videos and blogs documenting progress on this front.

The Smalltalk source code for the VM (aka "slang") was originally
included in all Squeak images, but in recent years has been maintained
as an external package (VMMaker) hosted in the source.squeak.org/VMMaker
repository.

Some portions of the VM (plugins) contain code that has not been
cleaned up for compiling on 64-bit platforms, and for this reason
it is common to compile VMs in 32-bit mode (-m32) for use on 64-bit
Linux, with the requirement that users install various 32-bit libraries.
If you are building a VM for your own use, you may prefer to compile
in native 64-bit mode.
