加载本机库时出现UnsatisfiedLinkError

Question

I'm trying to use native library from my java program. I can successfully load libpHash.so in /usr/local/lib by the following command.

System.loadLibrary("pHash");

But when I trying to load libpHash-jni.so in the same folder by calling System.loadLibrary("pHash-jni") I get the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/local/lib/libpHash-jni.so: libpHash.so.0: cannot open shared object file: No such file or directory

Why?

---

Some additional information:

• libpHash.so and libpHash.so.0 are both symbolic links to libpHash.so.0.0.0
• libpHash.so.0.0.0 and libpHash-jni.so are both ELF 64-bit LSB shared object
• I have 64 bit JVM

One possible solution is updating the dynamic linker cache with ldconfig . If this doesn't solve the problem you might also try setting LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/usr/local/lib

and restart your program.
