JNA will successively attempt to load frameworks from ~/Library/Frameworks, /Library/Frameworks, and /System/Library/Frameworks, based on the core framework name (EDSDK in this case).
If the loadLibrary
call succeeds, then the library was found. If the library was not found, you'll get an UnsatisfiedLinkError
.
Frameworks are basically bundles of a shared library with other resources; ESDK.framework/ESDK is the actual shared library (for frameworks, OSX omits the "dyld" suffix normally found on a shared library on OSX).
EDIT
Here's how to make a symlink so that the paths look more like what JNA is expecting. From a terminal (run Terminal.app):
% ln -s /your/complete/path/to/Macintosh/EDSDK.framework ~/Library/Frameworks/EDSDK.framework
When this is done successfully, you should see the following when listing (ls) the symlink:
% ls -l ~/Library/Frameworks/EDSDK.framework
lrwxrwxr-x 1 YOU YOU 50 Mar 31 01:13 /Users/YOU/Library/Frameworks/EDSDK.framework -> /your/complete/path/to/Macintosh/EDSDK/Framework/EDSDK.framework
You should see the symlink path (where JNA will look) on the left, with the path to the real file on the right. If not, delete the symlink file and try again. Note that you may need to create the directory ~/Library/Frameworks
first; it may not yet exist.
Finally, make sure that the library you're trying to load matches the VM you're trying to load with; 64-bit with 64-bit, 32-bit with 32-bit. Canon does not provide a universal binary of their library, so you'll need to point to one or the other or merge the two using lipo
.
