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 ...
Static linking is the result of the linker copying all library routines used in the program into the executable image. This may require more disk space and memory than dynamic linking, but is more portable, since it does not require the presence of the library on the system where it runs. Static linking also prevents "DLL hell", since each ...
It is one of the three mechanisms by which a computer program can use some other software within the program; the others are static linking and dynamic linking. Unlike static linking and dynamic linking, dynamic loading allows a computer program to start up in the absence of these libraries, to discover available libraries, and to potentially ...
A program that is configured to use a library can use either static-linking or dynamic-linking.Historically, libraries could only be static. [4] For static-linking (), the library is effectively embedded into the programs executable file, while for dynamic-linking the library can be loaded at runtime from a shared location, such as system files.
Historically, all library linking was static, but today dynamic linking is an alternative and entails inherent trade-offs.. An advantage of static over dynamic is that the application is guaranteed to have the library routines it requires available at run-time, as the code to those routines is embedded in the executable file.
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 time, but for static linking, the program is standalone. Smart linking is performed by a build tool that ...
A dynamic-link library (DLL) is a shared library in the Microsoft Windows or OS/2 operating system. A DLL can contain executable code (functions), data, and resources. A DLL file often has file extension.dll even though this is not required. The extension is sometimes used to describe the content of the file.
Examples of file formats use for both dynamic library and executable files include ELF, Mach-O, and PE. A dynamic library is called by different names in different contexts. In Windows and OS/2 the technology is called dynamic-link library. In Unix-like user space, it's called dynamic shared object (DSO), or usually just shared object (SO).
