[vtkusers] Compiling VTK on OSX with .jnilib extensions

[Thiébault Benoît]

Hi everyone,

It seems nobody has a solution for this problem... Here is a more detailed explanation of the issues I face in creating an OSGi bundle for VTK under OSX: http://dev.artenum.com/blog/ben/posts/osgi_vtk_and_macosx

I am sure that this would be very useful to many users, as it would allow them to develop Eclipse RCP applications using VTK.

I tried to do change the dylib extension to jnilib extensions myself, but I barely know CMake and I am sure there is a simpler way (that works...) to do it.

What I have done so far is first to identify what files in the build directory are referring to .dylib files. For this, I used the command:
grep -r -H ".dylib" .|awk -F':' '{print $1}'|sort|uniq|grep -v "^Binary"

The first file, CMakeCache.txt indicates path to system libraries, so I excluded it from the list.
I then replaced all .dylib occurrences by .jnilib extension. Yeah, I know, that's very brutal... if only it could have worked :-)
The compilation fails at 8%:

...

Can somebody help?

Thank you
Ben
