[squeak-dev] Can't get glMorphic to work

Hi i can't get gl morphic to work i've done everything as says in the  
squeak swiki, but when i try to run "GLDisplayScreen new".
a debugger comes out saying "Callout mechanism not available", i have  
copied opengl32.dll to squeak's directory with no results..
here is the debugger stack

'OpenGLAPI(Object)>>externalCallFailed'
'OpenGLAPI>>glGetIntegerv:with:'
'OpenGLAPI>>glGetInteger:'
'GLCanvas>>initialize:'
'GLDisplayScreen>>initialize'
'GLDisplayScreen class>>new'
'UndefinedObject>>DoIt'
'Compiler>>evaluate:in:to:notifying:ifFail:logged:'
'[] in TextMorphForShoutEditor(ParagraphEditor)>>evaluateSelection {[rcvr  
class evaluatorClass new   evaluate: self selectionAsStream   in:  
ctxt...]}' 'BlockContext>>on:do:'
'TextMorphForShoutEditor(ParagraphEditor)>>evaluateSelection'
'TextMorphForShoutEditor(ParagraphEditor)>>doIt'
'[] in TextMorphForShoutEditor(ParagraphEditor)>>doIt: {[self doIt]}'
'TextMorphForShoutEditor(Controller)>>terminateAndInitializeAround:'
'TextMorphForShoutEditor(ParagraphEditor)>>doIt:'  
'TextMorphForShoutEditor(ParagraphEditor)>>dispatchOnCharacter:with:'
'TextMorphForShoutEditor(TextMorphEditor)>>dispatchOnCharacter:with:'

Hello Gonzalo.
First: thanks for an interest (GLDisplayScreen  - is stuff written by
mine 2 years ago :) ).
Can you give some more details about what/from where you loading it,
on what image and what VM using.

At first glance, looks like you have problems with FFI package/dll.
Try run its tests to see if it working/present.

hi what a quick answer!! jeje, I used the vm that was availabe from the  
swiki page that says it has the opengl plugin compiled in, i tried several  
images from 3.8 to 3.10 basic and development versions, always used latest  
ffi package available, and followed instrucctions from the wiki!

hey! forgot the ffiprims.dll file :S, jaja. now it "works" pretty buggy is  
it supposed to be this way yet? or i should be able to see the screen  
correctly?
maybe i have an old ffiprims.dll where can i get a newer one?

2009/7/15 Gonzalo Romano <[hidden email]>: Aha.
Yeah its not fully complete and covers only most basic/commonly used
Canvas features.
Its really hard to make it work properly in all cases, because Morphic
is not the high quality code, which honors encapsulation rules &
capabilities delegation :)

jaja, yeah we know this for a long time!,
well, i'm pretty interested on making this work, i've no knowledge of  
openGl, but maybe doing some reading you could point me in the right  
direction...

2009/7/15 Gonzalo Romano <[hidden email]>: You can find a lot of resource about Opengl at opengl.org: books,
demos, tutorials, discussion board(s).
Do you think i can help you better than that?
Or, you mean in terms of Squeak/smalltalk? OpenGL API is bound almost
completely identically to squeak (thanks to people who made it
available). So you mostly don't need to know about any specifics,
apart from those which you can find about OpenGL in general.

Gonzalo,
I too am interested in this. I thought I would have to build "it", so  
I am thrilled to see your emails. And this hints at a few problems I  
am having, so if you would answer a few questions please, it would be  
much appreciated.

1. Where did you find glMorphic? And how? (I have done numerous  
searches using google and yahoo over the last 6 months and now found  
this.)

2. Where do I read the details (step by step), because I too would  
like to explore this. (And perhaps later this year I could help  
complete it.)

3. Are you finding it is *very* limited in features, or somewhat?

Thanks in advance,
Cam
