No regression, works fine. The binaries folder must be part of the PATH (e.g. using ldconfig) or set LD_LIBRARY_PATH. Otherwise we'll not be able to find the shared libs loaded at runtime. Check https://github.com/DoubangoTelecom/ultimateALPR-SDK/tree/master/samples/java/recognizer#examples LD_LIBRARY_PATH=../../../binaries/linux/x86_64:$LD_LIBRARY_PATH \ java Recognizer --image ../../../assets/images/lic_us_1280x720.jpg --assets ../../../assets

in our app i load the libraries by myself, its hard to change env variable outside the app what changed since 3.9.0 except for the name of the library in case of load library? did you get it to run 3.9.0 sample https://gist.github.com/Nook2007/9dbec85a9af2e9c3dbadf9da17bf67ec ? it worked before

This is normal behavior on Linux: You cannot load a dependency if it's not in the system libs, or registered using ldconfig or part of LD_LIBRARY_PATH. Why not run 'export LD_LIBRARY_PATH ....' before running your app? We have only changed the name of the lib in v3.9.0. But, we didn't rebuild it. I'll try to rebuild the lib, maybe the old name is referenced in the meta-data
