Auto-linking is a mechanism for automatically determining which libraries to link to while building a C, C++ or Obj-C program. It is activated by means of #pragma comment(lib, <name>) statements in the header files of the library, or @import <name> , depending on the compiler.
Translation units define a scope, roughly file scope, and functioning similarly to module scope; in C terminology this is referred to as internal linkage, which is one of the two forms of linkage in C. Names (functions and variables) declared outside of a function block may be visible either only within a given translation unit, in which case they are said to have internal linkage – they are ...
However, C is not a subset of C++, [3] and nontrivial C programs will not compile as C++ code without modification. Likewise, C++ introduces many features that are not available in C and in practice almost all code written in C++ is not conforming C code. This article, however, focuses on differences that cause conforming C code to be ill ...
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.
In computer science, link time refers to the period of time, during the creation of a computer program, in which a linker is being applied to that program. [ 1 ] [ 2 ] [ 3 ] Link time occurs after compile time and before runtime (when a program is executed ).
Linking can be done in two ways – using dynamic allocation and using array index linking. Linked data structures include linked lists, search trees, expression trees, and many other widely used data structures. They are also key building blocks for many efficient algorithms, such as topological sort [1] and set union-find. [2]
The motivation for writing gold was to make a linker that is faster than the GNU linker, [3] especially for large applications coded in C++. Unlike the GNU linker, gold does not use the BFD library to process object files. While this limits the object file formats it can process to ELF only, it is also claimed to result in a cleaner and faster ...
Dynamic linking offers three advantages: Often-used libraries (for example the standard system library) need to be stored in only one location, not duplicated in every single binary. If a library is upgraded or replaced, all programs using it dynamically will immediately benefit from the corrections. Static builds would have to be re-linked first.
