Dynamic linking or late binding is linking performed while a program is being loaded or executed , rather than when the executable file is created. A dynamically linked library ( dynamic-link library , or DLL, under Windows and OS/2 ; shareable image under OpenVMS ; [ 7 ] dynamic shared object, or DSO, under Unix-like systems) is a library ...
On Unix and Unix-like systems, the static linker is usually invoked via the command ld which is an abbreviation of LoaDer or Link eDitor. The term "loader" was used to describe the process of loading external symbols from other programs during the process of linking. [4] For example, on SINTRAN III, linking (assembling object files into a ...
An example of load-and-go systems is the loader Anthony J. Barr wrote for the University Computing Corporation in 1968 that was replaced in the market by the IBM OS/360 loader in 1972. These OS/360 loaders performed many of the functions of the Linkage Editor but placed the linked program in memory rather than creating an executable on disk. [9]
Any static library function can call a function or procedure in another static library. The linker and loader handle this the same way as for kinds of other object files. Static library files may be linked at run time by a linking loader (e.g., the X11 module loader). However, whether such a process can be called static linking is controversial.
Linking is often referred to as a process that is performed when the executable is compiled, while a dynamic linker is a special part of an operating system that loads external shared libraries into a running process and then binds those shared libraries dynamically to the running process. This approach is also called dynamic linking or late ...
The system's Linkage Editor application is named IEWL. [3] IEWL's main function is to associate load modules (executable programs) and object modules (the output from, say, assemblers and compilers), including "automatic calls" to libraries (high-level language "built-in functions"), into a format which may be most efficiently loaded by IEWFETCH.
Static linking is linking at build time, such that the library executable code is included in the program. Dynamic linking is linking at run time; it involves building the program with information that supports run-time linking to a dynamic link library (DLL). For dynamic linking, a compatible DLL file must be available to the program at run ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
