Unix Squeak

Welcome. You have reached the primary site for distributions of Unix Squeak. (Distributions of Unix Squeak downloaded from other sites will usually, but not always, be copies of the archives provided here.)

Squeak is a full-featured implementation of the Smalltalk programming language and environment based on (and largely compatible with) the original Smalltalk-80 system. Squeak has very powerful 2- and 3-D graphics, sound, video, MIDI, animation and other multimedia capabilities -- and one of the most impressive development environments ever created. It also includes a customisable framework for creating dynamic HTTP servers and interactively extensible Web sites. The entire Squeak system is open source software, distributed freely with a liberal license.

This page contains the latest releases of the Unix Squeak virtual machine. If you are downloading Squeak for the first time (and you cannot make use of the RPMs) then you might want to read the download page which gives detailed instructions on what to do.

Latest Release

These packages contain the latest release of Unix Squeak. The version history and release notes are at the end of this page. This version is believed to be suitable for general use, but please report any problems or bugs that you encounter.

Apologies in advance for missing entries in the table below. The set of machines to which I have access changes over time and it is not always possible to prepare releases for all relevant architectures and package formats.

Source Code Repository

You can check-out a self-contained set of sources (including all automatically-generated sources) from the Subversion repository. For the sources corresponding to a numbered release:

svn export http://squeakvm.org/svn/squeak/tags/unix-3.10-1

svn co http://squeakvm.org/svn/squeak/trunk squeak-svn

You can also browse the contents of the repository online.

(Unlike the old CVS repository at SourceForge, which was updated from my local sources whenever I was bored, I am currently using Subversion to for the primary copy of my sources. If you build a VM from the 'trunk' you'll be running the same VM that I am running.)

Generated Sources

Anyone who has tried to recreate the VM 'from first principles' knows that it is often difficult (or impossible) to assemble all the necessary pieces of the image in compatible versions. For that reason I am now archiving the images that I use to generate sources for every released version. Regenerating 'src' from this preloaded VMMaker image

Earlier Releases

If the above versions are too recent, many earlier releases are still available.

Release History

2008-04-11	3.10-1 released. Support for IPv6 added. Quartz display driver tries to open fullscreen window on correct screen. All keyboard input with valid UCS4 now generates input events. Window event generated when WM tries to close the Squeak window, giving the image the choice of how to deal with quitting. Various changes for OLPC. Support for dragging-and-dropping items from the image to other X11 apps. Platform support for locale plugin added. International input support added: dead keys, compose key, multikey characters, and composition overlay window. Manual page updated for new options and environment variables.
2006-10-10	3.9-8 released. ALSA support for Linux. Problems with iconv() fixed on Solaris.
2006-04-24	3.9-7 released. Modifications to the mechanism the VM uses to relinquish the processor for very short intervals to avoid high CPU loads while idling. UUIDPlugin is now external to prevent the VM failing to run when libuuid is missing or uncooperative. AioPlugin is bundled. Aliases are resolved in path names on OS X.
2006-04-19	3.9-4 released. KeyUp events are no longer reported for autorepeats under X11. Improvements to socket latency. Security plugin now obeys SQUEAK_USERDIR if set. OSProcess and XDisplayControl plugins updated from current distributions and bundled. The 3.9 Unix VMs are now fully compatible with Croquet and will run both Squeak and Croquet images. Additional plugins required for Croquet are now supported and bundled in both source and binary releases: CroquetPlugin, FloatMathPlugin and UUIDPlugin.
2004-04-06	3.7-7 released. Documentation updated to reflect recent organisational changes. 'gnuify' no longer requires gawk. Obscure bug in socket option lookup fixed. NPSqueak changes from Bert (SQUEAK_USERDIR environment variable overrides 'My Squeak', plus several bug fixes). Event code updated for recent changes to event structures. README, manual page, and how-to documentation updated and revised. Instructions for SVN checkout added. 'Easy build' route for checked-out SVN repository sources added. Browser plugin now supports imageName and failureUrl attributes within <embed ...> tag. Preliminary support for XDND-based drag-and-drop (Gnome, KDE, etc.) in the X11 display driver. New flag '-glxdebug <n>' prints OpenGL diagnostics in X11 display driver. Interpreter should no longer crash when loading image segments into memory above the 2GB boundary (thanks to Ned Konz). Additional checks for bad external data in SocketPlugin. Less inappropriate noise when probing for external plugins. Problems preventing more than one external plugin from loading in Mac OS X fixed.
2004-04-02	3.6-3 released. This is the 3.6 "final" release. Substantial rewrite of Mac OS X sound code for OS 10.3 (Panther). Better scroll wheel and 3-button mouse behaviour on OS X. Improved dock icon behaviour on OSX. New icons for OSX (thanks to Bert Freudenberg). Mac OS X dependency on libiconv removed. Dependencies on glibc2.3 in the 386 GNU/Linux version removed. Ephemeron support removed from the VM. Improvements to character set conversion on Solaris. Date/time reported on files now consistent with output from "ls". Backed out a problematic change in Socket>>primConnectionStatus. New dead key support for X11 (activated if LC_CTYPE/LC_ALL set); option "-nointl" turns it off. Several OpenGL fixes. Support for new Socket primitive listenOn:backlogSize:interface:. RPMs have "root.bin" ownership on everything. Problems with plugin and shared library searching fixed. Improved timing for Delays. Copy/paste compatibility problems fixed (thanks to Ned Konz). New OSProcessPlugin from Dave Lewis. Display/sound drivers are now dynamically loaded (and can be selected) at startup. New display driver "fbdev" for running on the Linux console.
2003-09-03	3.4-2 released. This is a maintenance release of 3.4 to back-port some improvements from the 3.6 build process. No new features or VM bug fixes are included. If 3.4-1 is working for you then you don't need to fetch this release.
2003-03-04	3.4-1 released. Rerelease of 3.4 to conincide with the final 3.4 image. The only fix is for an obscure problem with the INSTALL script in the binary tarball which was replacing symlinked dirs with fresh (empty) dirs before unpacking. (Thanks to L. Peter Deutsch for spotting this problem.) Enjoy!
2003-02-10	3.4-gamma1 released. A couple of subtle problems fixed concerning directory deletion and UDP packet reception (thanks to the vigilance of Ned Konz and Stefan Kersten). Completely new built-in support code for FFI prims (for SVr4-ish and Mach-O ABIs on Intel and PowerPC, entirely eliminating the dependency on libffi under Darwin and GNU/Linux). B3DAccelerator and OSProcess plugin support code updated. Note: there are no BSD binaries for this release. If you want me to build them, mail me.
2002-10-16	3.2-5 released. Build moved to autoconf 2.53. Lots of VM improvements (too numerous to mention: see the release notes). RePlugin (regular expressions) and FFIPlugin (foreign function calls) are bundled in this release (as external plugins). New browser plugin support is also bundled in this release and can be built along with the regular VM. PTYPlugin is now external (to make life easier for people who compile from source on systems that don't support ptys).
2002-07-11	3.2-4 released. Improves portability in the PTY plugin, ties up the last of the loose ends in BSD build, and fixes a couple of bugs in AsynchFilePlugin.
2002-07-09	3.2-3 released. Several build problems fixed, including support for compiling with -DHEADLESS. Tweaks to B3DAccel, Socket and browser plugin (eliminating a horrible pause on return from snapshot). Brand new in this release: OSProcess plugin, AsyncFile and PseudoTTY support.
2002-06-10	3.2-2 released. This fixes a serious bug in window code (thanks to Ned Konz who spotted it) and includes various changes to the build process needed to support rpm.
2002-06-07	3.2-1 released. This is the first stable release of Unix Squeak since 3.1pre1 (which was quite a while ago). Much of the windowing and sound code has been rewritten, the Netscape plugin code has been updated, and numerous contributed patches applied. To celebrate the event I decided to redesign the Unix Squeak site. Hope you like it. (This is used to be called 3.3.1, but that version has been retired. The confusion in the version numbering was imposed by a desire to keep the RPM and tarball version numbers consistent between the stable VM and the stable image. Given the choice between utter version confusion and respecting the monotonicity of time, I chose to make time jump backwards.)
