Eliot,
I have gotten a bit lost, but getting closer.
I am now able to run Squeak 5.0 on my ARM Chromebook via:
stkspurlinuxhtARM-15.24.3386.tgz
In Cog/image I loaded a Squeak5.0.image with BuildSqueakSpurTrunkVMMakerImage.st LoadReader.st StartReader.st
I then save & restart the image with the equivalent of squeak reader.image <Cuis4.2.image >Cuis5.0.image
But get a zero length Cuis5.0.image result.
As the reader.image quits immediately, I did not get to see what the code should be doing.
A usage hint would be helpful here.
Thanks much, -KenD
