[Vm-beginners] Objective-C

[Sean P. DeNigris]

How do I call objective-C code from Squeak/Pharo? 

The following tests were done with the Squeak 4.2.5beta1U VM... 

I loaded the "Objective-C bridge 2" project from SqS, and about half the
tests passed in Pharo 1.1.1. 
Evaluating: 
    bundle := ObjectiveCBridge classObjectForName: 'NSBundle'. "also tried
ObjectiveCObject>>findClassName:" 
    aBundle := bundle bundleWithPath: '/Applications/Mail.app'. 

Led to a primitive failure: 
primitivePerformSelector: aSelectorOop on: aClassorInstanceOop with:
argument1 
        <primitive: 'primitivePerformSelectorWith' module:
'ObjectiveCPlugin'>
        self primitiveFailed 


I tried the "ObjectiveCBridge" project in Squeak 4.2 final... 
Evaluating: 
    bundle := NSBundle bundleWithPath: '/Applications/Mail.app'. 

Led to a different primitive failure: 
primitiveIdFromString: aString 
        <primitive: 'primitiveIdFromString' module: 'ObjectiveCPlugin'>
        ^self primitiveFailed 

Thanks.
