errors while building a cog development image

 

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,

Hi Sophie, Hi Ben,

   thanks!  This issue is because until recently Squeak used ContextPart and MethodContext as the class names for contexts, while Pharo had changed to just using Context.  Now Squeak trunk is using Context too the compatibility package isn't needed.  I've updated the load script to eliminate CogCompatibility.st as you two both did.  That's pushed to github.  I'm also committing versions of VMMaker and Cog that no longer use the deprecated includedSubString:, so the builds should work less noisily now.

Sophie, welcome!  I for one would love to know what your plans with VMMaker are.
