It appears that Felix treats processor as a required attribute on the
native library, so you have to specify "processor=FOO" on the end of
your Bundle-NativeLibrary header. I added "processor=x86" and got it to
resolve on my Mac, but ended up getting errors when I started it:
Caused by: java.lang.UnsatisfiedLinkError:
/Users/rickhall/Projects/felix-trunk/main/felix-cache/bundle5/version1.1/bundle.jar-lib/0/vtk/osx64b/libvtkproj4.jnilib:
no suitable image found. Did find:
/Users/rickhall/Projects/felix-trunk/main/felix-cache/bundle5/version1.1/bundle.jar-lib/0/vtk/osx64b/libvtkproj4.jnilib:
mach-o, but wrong architecture
Not sure if processor should be required, but it seems like a good idea.

Hi everyone,
I am currently working on creating an OSGi bundle embedding VTK, the
Visualization ToolKit (http://www.vtk.org), written in C++, on Mac OS X.
I have written an article about my adventures and the related issues I have
encountered so far: http://dev.artenum.com/blog/ben/posts/osgi_vtk_and_macosx
The short story is that by default, the compilation configuration of VTK does
not create and link properly the dynamic libraries on Mac OS X. I thus had to
modify 3 things:
• change the .dylib extensions to .jnilib
• prepend the @loader_path prefix to the library transitive dependencies
• remove the version numbers from the library file names and
dependencies.
This way, I managed to execute the bundle without an UnsatisfiedLinkError with
Equinox. I however have a new problem, that seems much more complex to me.
When the bundle starts, it creates a "vtkPanel", which extends the AWT Canvas.
The rendering on the panel is then performed by a native method call that crashes.

This native method crashes when calling the jawt.h method
GetDrawingSurfaceInfo(ds), and I have no idea where it may come from.
The pure Java (no OSGi) application works fine, so I thought it could be
Equinox-related. This is why I tried to load the same bundle in Felix.
But here I have a new error message:
org.osgi.framework.BundleException: Unresolved constraint in bundle
test-osgi-vtk [5]: No matching native libraries found.
... and nothing more (even with log level at 4).
How can I know what does not work?
What did I do that is Equinox-compatible and Felix-incompatible? I don't recall
using specific Manifest entries...
