Exception UnsatisfiedLinkError

Question

I'm trying to run my project, but I have this exception and I don't know what to do next.

Details: in this project I need to use lib.jar, but this JAR file needs .so files.

Edit

    OpenJDK Server VM warning: You have loaded library /home/david/Retina/ReconocimientoRetina/sdk/libIddk2000jni.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Answer 1

Solution.

I solved my problem using this steaps

first

1-Add to LD_LIBRARY_PATH

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/foobar/lib

2-Rebuild cache

Open the /etc/ld.so.conf as sudo and add a new line with the library directory. In this case, we add /opt/foobar/lib.

3- Rerun ldconfig to rebuild the cache:

sudo ldconfig

4-Check if the shared library cache now includes the shared libraries from the new directory:

ldconfig -p
