Why do I get an UnsatisfiedLinkError when launching from the 64-bit Cocoa port?
You need to be sure that you are forcing your launch to use a 64-bit VM. Apple ships most of their VMs with 32 and 64-bit binaries. To force the VM to run in 64-bit mode, use the -d64 option as VM argument in your launch configuration. If you are launching with SWT from CVS in your workspace (see How to use SWT from CVS, use .classpath_cocoa as the .classpath file in the org.eclipse.swt project and make sure you have the org.eclipse.swt.cocoa.maxosx.x86_64 project in your workspace), then you also need to modify the .classpath file as follows: attribute value=”org.eclipse.swt.cocoa.macosx”change to: attribute value=”org.eclipse.swt.cocoa.macosx.
