Hey,

i got one step further by using Squeak VM 4.2.5beta1U with Pharo 1.2. I now am able to load JNIPort via the following:

	ConfigurationOfJNIPort project latestVersion load

When i want to start the JVM according to the description from the squeaksource wiki page i get the following error:




THERE_BE_DRAGONS_HERE

Error: primLoadLibrary: failed
16 February 2011 10:27:50 pm


VM: Mac OS - intel - 1066 - Squeak4.1 of 17 April 2010 [latest update: #9957] Squeak VM 4.2.5b1
Image: Pharo1.2rc2 [Latest update: #12335]


SecurityManager state:
Restricted: false
FileAccess: true
SocketAccess: true
Working Dir /Users/mjunker/Moose/Pharo-1.2
Trusted Dir /foobar/tooBar/forSqueak/bogus
Untrusted Dir /Users/mjunker/Library/Preferences/Squeak/Internet/My Squeak


JNIPortJNIInterfaceForMacOSX(Object)>>error:
	Receiver: a JNIPortJNIInterfaceForMacOSX
	Arguments and temporary variables: 
		aString: 	'primLoadLibrary: failed'

	Receiver's instance variables: 
		alienHandle: 	nil

		libraryName: 	nil

		errorStrings: 	nil

When i debug the method JNIPortJNIInterfaceForMacOSX>>load the library name seems to be set correctly to:


/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Libraries/libjvm.dylib


I checked and found that this is a symbolic link to:


/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Libraries/libclient.dylib

So far everything looks alright. I attached the Debug.log with all the detail.

Any help is appreciated.

Cheers

Matt

And another thing: 

can anyone explain what the IAB32 plugin is? The wiki page says:

To use JNIPort for Pharo and Squeak, you need a Squeak virtual machine with the IAB32 plugin which contains the primitives used by the Alien foreign function interface library.

Can anybody explain what this means? Is this already included when i download squeakvm or do i have to do anything else? i couldn't find anything on this subject.

Cheers

Matt
