Description

A kind of chained library Compilation Method of dynamically obtaining UID
Technical field
The present invention relates to the application program of mobile phone field of portable terminal, especially a kind of chained library Compilation Method of dynamically obtaining UID.
Background technology
Dynamic link library, it is the abbreviated form of Dynamic Link Library, dynamic link library (DLL) is the executable file as the Sharing Function storehouse.Dynamic link provides a kind of method, makes process can call the function that does not belong to its executable code.The executable code of function is arranged in a DLL, and this DLL comprises and one or morely separate the function of storing by compiling, link and with the process of using them.DLL also helps to share data and resource.A plurality of application programs are the content of single DLL copy in the access memory simultaneously.DLL is one and comprises the code that can be used simultaneously by a plurality of programs and the storehouse of data.For example, in Windows operating system, Comdlg32 DLL carries out the common function relevant with dialog box.Therefore, each program can use the function that comprises among this DLL to realize the Open dialog box.This helps lend some impetus to effective use of code reuse and internal memory.
By using DLL, program can realize modularization, is made up of relatively independent assembly.For example, the program of accounting can be sold by module.Can be with each module loading in master routine (if corresponding module be installed) when operation.Because module is independent of each other, so the loading velocity of program is faster, and module only just loads when corresponding function is requested.
Under the static library situation, function and data are compiled into a binary file (expansion * .LIB by name usually), and the compiler of Visual C++ will recover these functions and data and they are generated executable file with other module combinations in the application program together from static library when handler code.This process is called " static linkage ", and this moment is because the required full content of application program all is to have copied from the storehouse, so static library itself does not need to issue with executable file.
The advantage of DLL is that when a plurality of programs were used same function library, DLL can reduce the amount of repetition of the code that loads in disk and physical memory.This not only can influence the program at front stage operation greatly, and can influence the program that other move in Windows operating system greatly.
DLL helps lend some impetus to the modular procedure development.This can help your development requires that the large program of a plurality of language versions or the program that requirement has the modular architecture are provided.An example of modular program be have a plurality of can be in the program that accounts of module of when operation dynamic load.
When the function among the DLL need upgrade or repair, dispose and install DLL and do not require linking of the program of rebuliding and this DLL.In addition, if a plurality of program is used same DLL, so a plurality of programs will benefit all will or repairing from this renewal.When you used the third party DLL of regular update or reparation, this problem may occur more continually.
Static-link Library and Dynamic-link be a kind of line module it provide the complete object code (in static library * .lib) of function if the function of the Static-link Library and Dynamic-link in the routine call, then when connecting linker with in the code of this function of comprising copy in the operating file. the object code of its function that provides also has been provided dynamic link libraries, but when program connected function in the dynamic link libraries, linker did not block that the object code that is included in the function in the dynamic link libraries copies to operating file and the positional information that just simply recorded function.
Along with extensively popularizing with intelligent of mobile phone, mobile phone can be installed different application programs and offer functions such as consumer entertainment or recreation, when some DLL is used in a plurality of application programs, name conflict will occur, the programmer has to manually change to different name copies for these DLL, and need update routine, so that these DLL can correctly be loaded, this technology is obscured easily, make mistakes, and all to change program at every turn, recompilate, very trouble.For example, the mobile phone end is installed the mobile TV program earlier, and correspondence A under the storage catalogue of mobile phone comprises a core player storehouse, and this core player storehouse comprises a static library and three dynamic base, respectively called after: tmpc.lib; Tmpc.dll; Net_plugin.dll and Mp4plugin.dll, when mobile TV routine call core player, code among the tmpc.dll is write to be decided to be and is loaded Net_plugin.dll and Mp4plugin.dll, when the mobile phone end is installed a watchdog routine again, it needs equally to use core player storehouse identical with the mobile TV program, then needs manual with tmpc.lib; Tmpc.dll; Net_plugin.dll and Mp4plugin.dll rename respectively and are made into copy and are stored under the identical directory A, for example are renamed as tmpc0.lib respectively; Tmpc0.dll; Net_plugin0.dll and Mp4plugin0.dll, because originally writing to be decided to be, the code among the tmpc0.dll loaded Net_plugin.dll and Mp4plugin.dl, therefore also need the program of manual modification tmpc0.dll for loading Net_plugin0.dll and Mp4plugin0.dll, recompilate, when monitor call core player storehouse, the program of tmpc0.dll is for could successfully load Net_plugin0.dll and Mp4plugin0.dll, above process bothers very much, normally the programmer finishes, common cellphone subscriber generally can not finish, this makes the cellphone subscriber after an application program is installed, and an application program of using identical player storehouse is installed again brings very big puzzlement.
Given this, be necessary to propose a kind of improved method to overcome the defective of prior art in fact.
