Hi Trygve, Did you see my earlier reply suggesting that you use the VM at http://www.squeakvm.org/~lewis/MacOS-test-Javier/ ? I believe that I sent it directly to your personal email address, but I don't know if you received it. The newer Cog VMs used in Squeak all-in-one and Pharo will not work with a Squeak 3.10 image, but any of the traditional context interpreter VMs (including this recently built VM provided by Javier Diaz-Reinoso) should be fine. A bit off topic from your orginal question, but I would also encourage you to take a look at http://try.squeak.org/ as a source of inspiration. This is Bert Freudenberg's remarkable SqueakJS running in a web browser, and it might prove quite suitable for certain kinds of software demos where you want a run-anywhere capability. You should be able to drag and drop your BabyIDE image onto that web page, and run it directly in your your web browser with no need to install a VM at all. HTH, Dave
Hi Chris, I'm sorry to say that your advice didn't work. Worse: The Squeak community has lost a valuable contributor, a prime mover in the patterns and agile communities and the author of several books on OO. My friend wrote: " /I still canâÂÂt find a version of Squeak for my Mac that will run TrygveâÂÂs current BabyIDE. At this point, even if one appears, it is obvious that my dependence on âÂÂthe introvert Squeak communityâ will put me in a much more fragile position than with any of my other concept proofs. It will be extremely difficult to build a future on such fragile foundations./"
I came to Xerox PARC and Smalltalk in 1978 where I made my contributions to Smalltalk-80. Since then, I have been working almost exclusively with Smalltalk. My company invested in a VW class library of more than 100,000 lines of Smalltalk code and used it in our consulting. A strong selling point was that our tenders were accompanied by a demo version of the program we offered to deliver. Our library and applications were repeatedly threatened by new versions of VW. The code is now dead; there is no VM that will run our old images. The investment is lost.
I hoped Squeak would be better. It isn't. Squeak is less stable than VW ever was. My new programming paradigm, DCI, is supported by BabyIDE that runs under Squeak 3.10. I have ported BabyIDE to 4.5, but there are new bugs caused by differences between 3.10 and 4.5. The result is that I have reverted to 3.10 because it's too much hassle to run after the stream of Squeak releases. I thought Pharo would be better, but their mailing list conversations indicate that they do not understand that developers need a stable foundation for their work.
The result is that I too leave Smalltalk and concentrate on other environments. A pity, because I still believe Smalltalk has the potential to become a superior environment for non-professional programmers. I am particularly thinking of children and experts such as computational chemists who use computers in their work.
It's very painful, but I am now terminating development work in Squeak leave the Squeak and Pharo mailing lists. I will continue my work in some mainstream language. I have just done some work in Java with Netbeans and I am buying a book on JavaScript. It's heavy going, but better that working for the dustbin.
Cheers --Trygve

You need a non-Cog vm. I usually download any Etoys vm. [1] From there, drag it onto the vm or right click, choose âÂÂOpen Withâ and choose Etoys.
