See http://www.mirandabanda.org/cogblog/build-image/You'll want to redefine the GetGoodVM.sh or GetGoodSpurVM.sh scripts to run the relevant VM (if I recall the names correctly).[2] Is there a Non-Cog Spur VM available? [Chromebook currently does page protect to disallow JIT]Yes. In http://www.squeakvm.org/svn/squeak/branches/Cog/spurstacksrc is a non-Cog Spur VM and there are pre-configured builds for it in eg http://www.squeakvm.org/svn/squeak/branches/Cog/build.linux32x86/squeak.stack.spurNote that VMMaker.oscog /should/ load and run in non-Spur squeak but I've not tried this for over a year now.
Thanks much,
-KenDPerhaps some time we can discuss what's necessary to get Cog VMs running on Chromebooks. Is it a matter of doing the entry into machine code appropriately or is there a deal breaker or...?
