Re: [Pharo-project] Kernel

by Alexandre Bergel

Hi Ben, I tried, and it works. But what can I do then? When I run your image (by just double clicking on it), I have a sound without nothing appearing. Do you have some more information about Hazel? What can I do with the image? How can I use it?

[Pharo-project] Kernel

by Benjamin

Hello guys, I finally success (with the help of Igor) to trace and create a new Smalltalk kernel based on Pharo. The new born weight 2.2Mb and includes 230 classes ;) You can try it here: Gofer new squeaksource: 'PharoTaskForces'; package: 'SystemTracing'; load. Gofer new squeaksource: 'Seed'; package: 'Seed-HazelBuilder'; load. HazelTracer2 writeImage: 'hazel.image'. If you have an error in Point>>#printOn: , you can use this fix I want to thank Igor again, because he helps me a lot :) Ben
