Hi,

I have tried to build a cog dvlpt image using the following instructions :

$ git clone http://www.github.com/OpenSmalltalk/opensmalltalk-vm

$ cd opensmalltalk-vm/image

$ ./buildspurtrunkvmmakerimage.sh

while running the script, i get 2 errors (see attached file):

- "Context cannot be changed"

- and then "stackp store failure"

which prevent me from actually building the image (the last error goes in an infinite loop)

Has anyone ever experienced this problem?

I am using Ubuntu 15.10, 64 bits.

Thanks

Sophie

I tried this myself and noticed it fail when loading "CogCompatability".

If you look down the stack to "MCClassDefintion>>createClass", 

the instance variable "name" holds #Context.

Context has only recently been introduced to Squeak.  

Previously it needed to be loaded by "CogCompatability".

Now its an error for "CogCompatability" to try redefining this core system class.

I got it to work by removing "CogCompatability" 

from the manifest in BuildSqueakSpurTrunkVMMakerImage.st  ...

    manifest := #(

        ('http://source.squeak.org/FFI' 1 ('FFI-Pools' 'FFI-Kernel'))

  ('http://source.squeak.org/VMMaker'  6

             ('Balloon-Engine-Pools' 'BytecodeSets.spur'  'VMMaker.oscog' 'CogCompatibility'  .....

And then running ./buildspurtrunkvmmakerimage.sh,
