Finally managed to carve out some time to try this again. It looks like a few people have been looking into to this in the meantime (thanks a lot) and even though I can’t follow exactly what has been changed etc I can report that when I clone the latest opensmalltalk-vm I can get a working system. I can open a workspace and Try a few tests with no crashes: (10**22) sin -0.8522008497671888 fib := [ :n | n > 2 ifTrue: [(fib value: n-2) + (fib value: n-1)] ifFalse: [1]].

I used a minimal install for org and a simple wm: openbox Then did a git clone of: https://github.com/OpenSmalltalk/opensmalltalk-vm <https://github.com/OpenSmalltalk/opensmalltalk-vm> I changed the shell to bash then did: ./scripts/updateSCCSVersions Then I changed to opensmalltalk-vm/building/linux64x64/squeak.cog.spur/build Ran: ./mvm Down loaded the latest Squeak6.0-22104-64bit.image & .changes and renamed them in the dir to squeak.image & squeak.changes. I copied the SqueakV60.sources here too. ./squeak ran. I accepted all the defaults for configure & then installed system updates, FFI, and OS system. And that’s it.

I particularly enjoy reading the "Chapter summary" sections, I still find myself learning or relearning something each time I do that. Dave

Specifying method names in Squeak 6.0
by lcuff2＠yahoo.com 02 Jul '23

02 Jul '23

I'm following the instructions in Squeak By Example (SBE), edition 5.3. On page 32 it gives code for SBECell initialize. When I type the exact code (excerpted below) It turns everything after the »red. When I accept it, I get "Nothing more expected". If I delete the "» initialize", it gets syntax colored and looks valid, but the method name is no longer initialize. Is this a change from Squeak 5.3 to 6.0. Should I download Squeak 5.3 in order to use the SBE book? SBECell»initialize super initialize. self label: ''; borderWidth: 2; bounds: (0 @ 0 corner: 16 @ 16); offColor: Color cantaloupe; onColor: Color aqua; useSquareCorners. self turnOff.
