Shared libraries can't be redistributed since they refer to their build path

Hi everyone,

I am building VTK 9.1 for Java for few platforms as I could not find VTK java build on CDash (I hope I am not wrong). I make this open and available for download to anyone.

My problem is that I recently noticed that some of the shared libraries built with CMake hold a reference to the path of my development computer. I hence can’t load them properly despite defining java.library.path=/path/to/where/vtk/shared/libs/were/downloaded

When starting a program, I got UnsatisfiedLinkErrors referecing the path where the libraries have been built on my dev computer.

Reason: tried: '/Users/martin/Dev/jzy3d/external/VTK-9.1.0-build2/lib/libvtkCommonMathJava.jnilib' (no such file), '/Users/martin/Dev/jzy3d/external/VTK-9.1.0-build2/lib/java/vtk-Darwin-x86_64/libvtkCommonMathJava.jnilib' (no such file), '/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home/lib/libvtkCommonMathJava.jnilib' (no such file), '/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home/lib/server/libvtkCommonMathJava.jnilib' (no such file), '/Users/martin/Dev/jzy3d/external/VTK-9.1.0-build2/lib/libvtkCommonMathJava.jnilib' (no such file), '/Users/martin/Dev/jzy3d/external/VTK-9.1.0-build2/lib/java/vtk-Darwin-x86_64/libvtkCommonMathJava.jnilib' (no such file), '/Library

The variables CMAKE_SKIP_INSTALL_RPATH and CMAKE_SKIP_RPATH are unchecked (I understood they should remain unchecked)

Any help on dropping the path of the developer machine in a shared library?

Thanks!

Hello,

I don’t know much about JNI, but I assume you’re on some POSIX system (rpath). Have you tried to add the path where the VTK libraries are to LD_LIBRARY_PATH (DYLD_LIBRARY_PATH in MacOS)? If your system is not something from Mars, it should search for libraries there before looking in the executable’s rpath entries.

regards,

Paulo

Thank you Paulo, referencing the lib path in DYLD_LIBRARY_PATH instead of java.library.path solves the problem on macOS. For Windows, I could make it work by adding it to PATH. I haven’t tried Ubuntu yet, but I think this will work with LD_LIBRARY_PATH.
