Error while loading shared libraries; cannot open shared object file: No such file or directory

Question

I have problem when loading shared libraries (JNI) from java class on Ubuntu operator system

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/ETcpsdk/lib/linux-x86_64/libjcryptoki.so: libcryptoki.so: cannot open shared object file: No such file or directory
    at java.lang.ClassLoader$NativeLibrary.load(Native Method)

    at tutorialjni.Test.<clinit>(Test.java:7)

- Test.java

package tutorialjni;

public class Test {

    // Load an external library, called "jcryptoki"
    static {
        System.loadLibrary("jcryptoki");
    }

    public static void main(String[] args) {
        System.out.println(System.getProperty("java.library.path"));
    }

}

- LD_LIBRARY_PATH was allocated in /etc/environment

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME="/opt/jdk1.7.0_75"
LD_LIBRARY_PATH="/opt/ETcpsdk/lib/linux-x86_64:/opt/ETcpsdk/lib/"

And I own ETcpsdk folder.

• libcryptoki.so put in /opt/ETcpsdk/lib/linux-x86_64/libcryptoki.so

• Run file libcryptoki.so command

  libjcryptoki.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped

- JDK version:

java version "1.7.0_75"
Java(TM) SE Runtime Environment (build 1.7.0_75-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.75-b04, mixed mode)

- Ubuntu:

Distributor ID: Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:    14.04
Codename:   trusty

I added library directory to ldconfig cache

Can you help me?

Answer 1

I got this problem because my shared libraries depends on another shared library which works improperly.
