Re: [vwnc] Store Magritte download - smallwiki

Dear Nial,

Well if you actually manage to port Margritte and Pier 1.2 to VisualWorks that would be
really Cool (don't hesistate) !

Pier is a cool thing, it doesn't have  a lot in common with SeaBreaze and WebVelocity
but simply works to make good web sites.

I am awaiting the day that glorp.org get's on to it.

Sincerely yours,    

@+Maarten,

 Dear Miguel,
    proceed as follows

 1) Load Porting-NameSpaces CS14.NFR.15.  The atomic loader works with 
 the latest Porting-NameSpaces but it cannot load both the 
 Porting-NameSpaces system _and_ a FirstFindNameSpace (e.g. Magritte) in 
 the same atomic operation.

 2) Load Magritte-All nfr.295-1 and take latest in repository for all 
 prompted prereqs.

 3) Load MagritteForVisualWorks nfr.295.  Instead of (2), you can load 
 just this, taking Magritte-All version nfr.295-1 as prereq when 
 prompted.  The only reason to load them separately is to observe the 
 references to a few Undeclared that will appear after Magritte-All is 
 loaded.  After MagritteForVisualWorks is loaded, most of these 
 Undeclared will say they have no references, since the locations are now 
 overridden.

 Thorsten and I ported the 295 version at ESUG in September last year.

 I have also published a version of Pier (lr.183-222-81-99 CS14.NFR.11) 
 to the repository that prereqs MagritteForVisualWorks and also has a 
 viable Pier FirstFindNameSpace, so loads OK.  The Squeak Pier version 
 from which this was ported was the current version in late 2007;  I will 
 port a newer version sometime (or will be pleased to discover that 
 someone else did so ahead of me. :-)

          Yours faithfully
             Niall Ross

  Thanks Alan

 Second attempt. No success.

 1. I turned off Atomic loading in the settings.
 2. Tried loading MagritteForVisualWorks (trs.295,trs)
 3. Selected latest package when prompted
 4. Got loads of errors on the Magritte.* packages (see below).  From 
 what I can see methods were added to Object and various core classes 
 but hardly any new classes created. Squeak.* packages loaded fine

 I'm not sure if I'm mis-posting this here. I've noticed on this thread 
 someone forwarding to the seaside mailing list. Perhaps I should post 
 there instead?

 Regards Miguel

 Error dump follows All packages gave similar errors.:

 Warning: Package "Magritte-Model" cannot be loaded.

 The following classes cannot be loaded because their environment is 
 not in the image nor in the package being loaded:  
     MAPriorityContainer (environment path: Root.Smalltalk.Magritte)
     MAPluggableAccessor (environment path: Root.Smalltalk.Magritte)

  There seems to be an issue there with Magritte
attempting to extend 
 namespace semantics, and defining a namespace with 
 defineFirstFindNamespace: ... which the atomic loader does not like. 
 It looks like someone published a version which claims it deals with 
 this problem, but it doesn't seem to. You can try going to the Store 
 settings, and under Loading policies turn off "Use the Atomic 
 Loader". There are other things you can do, and someone should really 
 fix that, but that's probably the easiest thing for a beginner.

 You probably also want to load MagritteForVisualWorks rather than 
 Magritte-All. Other than the namespace issue, and a walkback in 
 trying to initialize, that was fairly easily bypassed, it seemed to 
 load OK. But I didn't try to run it.

  Hi all,

 I would like some assistance in getting Magritte installed from the 
 public repositroy.

 I'm trying, unsuccessfully so far, to load the Magritte package into 
 VW7.7nc image. After some initial problems with connecting to the 
 store with James Robertson kindly helped me with I'm connecting 
 successfully to the store.

 As instructed in the package comments I have turned off atomic loads.

 I'm first getting Magritte-all (trs,295,trs) and I'm getting loads 
 of messages with unloadable definitions and the end of which I have 
 Magritte package definitions and some methods created in existing 
 classes. I have no (as far as I can tell) Magritte classes created.

 As I'm new to VW, the public repository I would appreciate if 
 someone could give me a pointer to get up and running. Perhaps I'm 
 trying to load an unstable version, or there is some implicit 
 dependency on another package.

 Best Regards,

 Miguel Sanchez
