If I understand correctly, here is what we need to do:
1) Apply the changes of Mr Hachisuka to the VM.
- The diff is in the earlier email from Yoshiki:
- Test updated VM to make sure the changes do not cause problems. Make sure
it works without problems for Squeak trunk and for Scratch.
- Apply the update in SVN for both oscog and trunk. I can help here.
- Test the VM. Tim, I need help on this. I do not currently have a working
Cog build environment (Unbuntu/autotools/gcc version issues). Can you
apply the patch from Yoshiki's email and see if your resulting Cog VM
continues to work for you as expected on Pi with Scratch?
- Yoshiki, we should give credit to Mr Hachisuka for his contribution. Can
you please give his full name for the commit notice? I assume the patch
is MIT licensed.
2) Make updates to the image.
- Start with Yoshiki's recommendations.
- Make sure that it works in Scratch, and that all updates are also in
3) Make updates to the scripts that call Scratch from the menu (see above,
4) Confirm that Scratch users around the world are happy :-)
