【摘要】 结合ELF共享库文件格式,研究了Linux系统动态链接的机制和原理,论述了实现的关键技术:PIC代码,全局偏移表GOT,过程链接表PLT;分析了动态库的加载映射过程以及符号解析技术。利用Linux的动态链接机制实现了共享库重定位的应用。更多还原

【Abstract】 The technological details about dynamic link mechanism are researched,with specific ELF shared object file.Critical questions are illustrated which include: position independent code(PIC),global offset table(GOT),procedure link table(PLT),linking and mapping of dynamic libraries,and symbols resolving.The paper suggests the redirect application of shared library with dynamic link technology.更多还原
