概念：
     static library: 打好包的程序， 每个调用都会复制一份到内存。
     shared libray<beginning linux programming>: When a program uses a shared library, it is linked in such a way that it doesn’t contain function code itself, but references to shared code that will be made available at run time. When the resulting program is loaded into memory to be executed, the function references are resolved and calls are made to the shared library, which will be loaded into memory if needed.
