Hi !
I manually loaded NBOpenGL from SmalltalkHub and SourceCity on moose 4.8,
with the default vm proposed on moose's website and it works.
There is a sourcecity and GLTest example.
image.zip : https://www.dropbox.com/s/4v9m5eig7qs4xez/sourcecity.zip
vm : http://www.pharo-project.org/pharo-download/release-2-0
I tested it on win 8 64bit. It'll not work on linux. I don't know about mac
os.
I will update the ConfigurationOfSourceCity, but i have to write my
internship's report for the moment.
Sorry for the unexpected troubles

Hi guys
I tried to run your hello world example.
I first loaded ConfigurationOfSourceCity in a Moose 4.8 development
image and
tried to run it.
Then I loaded it in a Pharo2.0 image and failed
the same.
I tried to load the image using a NBCog VM (latest).
What am I doing wrong?
Cheers
Ricky
