Thanks to the help here I have now created the interface for Javafx (https://github.com/lanthale/LibRawFX).
Nevertheless I am asking which native libs must I package with the shared lib (libraw.dll / libraw.20.so / ...) so that libraw is working as expected and the user does not have on a standard system (libjasper ?, libjpeg ?).
I am not an C expert and therefore I do not know if the libs are only compile dependend libs or if those libs are needed for runtime as well ?
Thank you in advance.
