在Ubuntu下使用JNI在IntelliJ中包含native C++ .so庫

Question

我正在構建一個共享庫，它將在Ubuntu 14.04 x64下使用JNI從Java IntelliJ調用。 當調用的IntelliJ使用System.loadLibrary("libtestJniLib")我的.so文件，我得到了以下錯誤：

Exception in thread "main" java.lang.UnsatisfiedLinkError: no 
libtestJniLib in java.library.path 

的配置的IntelliJ確定庫的路徑：

1) Run->Edit Configurations->VM options: -Djava.library.path=/home/username/Libs 
2) In "Project structure -> Libraries ->Native library locations" 

我加了相同的路徑：/home/username/Libs

當使用下面提到的方法測試它時，我有一條正確的路徑。

String javaLibPath = System.getProperty("java.library.path"); 

IntelliJ以root啓動。

當你加載使用System.LoadLibrary()共享庫，應用如下：

Loads the system library specified by the libname argument. The manner in which a library name is mapped to the actual system library is system dependent.

我能找到該映射的最好描述是here：

Each Java runtime environment provides a platform-dependent mechanism for mapping between the actual file name of a shared library and the name string that you pass as an argument to the System.loadLibrary method.

Solaris:

The shared library file name requires a "lib" prefix and a ".so" extension. Do not include the "lib" prefix or the ".so" extension for the argument that you pass to the System.loadLibrary method.

Microsoft Windows:

The shared library file name requires a ".dll" extension.
Do not include the ".dll" extension for the System.loadLibrary method argument.
