Abstract

A shared library system and method of building the system are disclosed. A run-time loader and a compiler are modified, and a pattern of a previous shared library is changed using a library builder. Furthermore, by using a data section base register and a global offset table of a data section, it is possible to use a shared library even without a memory management unit.

Description

technical field [0001] The present invention relates to a shared library system in which a single library instance is shared by multiple applications, and in particular to a shared library system and a method of building the system such that it is possible to use a shared library without a memory management unit (MMU) . This application claims priority based on Korean Patent Application No. 2003-47538 filed with the Korean Intellectual Property Office on July 12, 2003, the entire disclosure of which is hereby incorporated by reference. Background technique [0002] Generally speaking, a library consists of code and a data area for the data used in that code. Depending on whether multiple applications share and use the library code, libraries can be classified into static libraries and shared libraries. For static libraries (usually files of type *.a), the library code is copied during the link step and used with the application. For shared libraries (usually files of type...
