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 ...
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 ...
In OS/360 and descendant systems, the (privileged) operating system facility is called IEWFETCH, [2] and is an internal component of the OS Supervisor, whereas the (non-privileged) LOADER application can perform many of the same functions, plus those of the Linkage Editor, and is entirely external to the OS Supervisor (although it certainly ...
DFSMSdfp [e] replaces the older direct, index and sequential access methods, the utilities and service aids, the linkage editor, the loader and program fetch. It is the component to which new device support code is added.
When the program is run, a dynamic linker or linking loader associates program library references with the associated objects in the library. A dynamic library can be linked at build-time to a stub for each library resource that is resolved at run-time. [1] Alternatively, a dynamic library can be loaded without linking to stubs.
Bit 0 to 3 of a segment handle are (by definition of a Geos handle) always 0. […] all Geos API run through the "overlay" scheme […]: when a Geos application is loaded into memory, the loader will automatically replace calls to functions in the system libraries by the corresponding INT-based calls.
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]
An illustration of the linking process. Object files and static libraries are assembled into a new library or executable. In computing, a linker or link editor is a computer system program that takes one or more object files (generated by a compiler or an assembler) and combines them into a single executable file, library file, or another ...
