加载共享库时出错; 无法打开共享对象文件:没有这样的文件或目录

Question

从Ubuntu操作系统上的java类加载共享库(JNI)时遇到问题

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 java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1965)
    at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1890)
    at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1880)
    at java.lang.Runtime.loadLibrary0(Runtime.java:849)
    at java.lang.System.loadLibrary(System.java:1088)
    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已在/ etc/environment中分配

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/"

我拥有ETcpsdk文件夹.

• libcryptoki.so放入/opt/ETcpsdk/lib/linux-x86_64/libcryptoki.so

• 运行文件libcryptoki.so命令

  libjcryptoki.so:ELF 64位LSB共享对象,x86-64,版本1(SYSV),动态链接,未剥离

- JDK版本:

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

我将库目录添加到ldconfig缓存中

你能帮助我吗？

我遇到这个问题是因为我的共享库依赖于另一个工作不正常的共享库。
