The following example shows the control statements that instruct the OS/360 Linkage Editor to link an overlay program containing a single region, indented to show structure (segment names are arbitrary):
A linker or link editor is a computer program that combines intermediate software build files such as object and library files into a single executable file such a program or library. A linker is often part of a toolchain that includes a compiler and/or assembler that generates intermediate files that the linker processes.
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.
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 ...
Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. [1] [2] Prior to the advent of multiprocess systems, and still in many embedded systems, the addresses for objects are absolute starting at a known location, often zero.
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 Wing Python IDE is a family of integrated development environments (IDEs) from Wingware created specifically for the Python programming language with support for editing, testing, debugging, inspecting/browsing, and error-checking Python code.
