VTK java.lang.UnsatisfiedLinkError

Support
1

Trying to run/debug my project using intellij (windows), got errors like:

java.lang.UnsatisfiedLinkError: no vtk{Anything} in java.library.path

{Anything} can be any class of vtk i’m trying to use, for example:

java.lang.UnsatisfiedLinkError: no vtkRenderingCoreJava in java.library.path
java.lang.UnsatisfiedLinkError: no vtkFiltersModelingJava in java.library.path
java.lang.UnsatisfiedLinkError: no vtkViewsContext2DJava in java.library.path
etc...

I know this problem can be solved adding -Djava.library.path= to VM option. I had a very similar problem with simpleITK and solved it: Where do i get SimpleITK JNI Lib?

But my answer now is: How can i get JNI lib for vtk? Or native lib? Or any file that solves my problem? I tried with this one but doesn’t work: https://people.ece.ubc.ca/andrewkh/vtk-jni.html

then, i try following this: installation of vtk 9.0 with python, java wrappers

i ‘git clone VTK’ and use cmake/visual-studio to make a build. configuration is Debug x64 ALL-BUILD, using VTK_WRAP_JAVA=ON. my build finish with no errors, but now i dont know what is the path to the file that i need to put into -Djava.library.path=

Normally if your target is just Java, you have other options (in cmake) that will build a jar with those dlls in. So that path should not be an issue either.

Can you please provide the names of these options? Or at least give me an idea of what they are called? Thanks!!

just for complement, running this:

        int totalNotLoaded = 0;
        if (!vtkNativeLibrary.LoadAllNativeLibraries()) {
            for (vtkNativeLibrary lib : vtkNativeLibrary.values()) {
                if (!lib.IsLoaded()) {
                    totalNotLoaded += 1;
                    System.out.println(totalNotLoaded + " - " + lib.GetLibraryName() + " NOT LOADED");
                }
            }
        }
        vtkNativeLibrary.DisableOutputWindow(null);

prints this:

run ccmake or cmake-gui and search for java.

5

there is just one named VTK_WRAP_JAVA, i tagged it and did the build.
No errors, but now where are the dll’s?

Nothing more in the advanced list? If that is the case, maybe it happen by default on install. Did you run cmake --install --prefix ./install .
