| | Which is better, static or dynamic linking? - SunWorld - February 1996 |
 | | A property of dynamic linking is that it defines the dependencies between software modules that are expressed in terms of the interfaces through which they interact rather than a (often very temporal) relationship based on the status and behavior of the implementation. | | | By using the default configurations of libraries which are dynamically linked, you are insulated from bugs or limitations in the implementation which would otherwise become part of your program. | | | We'll start by examining the differences between static and dynamic linking, then move on to the reasons why dynamic linking is preferred. |

| | Dynamic Hypertext: Querying and Linking |
| | Precomputed links can be constructed at any time, whereas dynamic links are computed at the moment they are required [Ashman 1997]. | | | In this approach, the link is not defined as a pointer from one hypertext node to another, but rather as a query that leads to a different node. | | | However, disadvantages include computation of each link at run-time (instead of using stored, precomputed links), which can be expensive in a large system with many users [Ashman 1997]; over-completeness, which occurs when the reader is presented with more links then he/she can comprehend [Thistlewaite 1997]; and problems with "paradoxical" or false links. |

| | Zen and the Art of Dynamic Linking |
| | During run-time linking this table was initialized by the Run-time linker to the values of externals. | | | In run-time linking, the component is loaded into memory and the other [external] shared library components are connected before execution. | | | In Dynamic Run-time Linking no binding is done for external references to the shared object until the component tries to access the reference. |

| | Dynamic Linking and Loading |
| | Since dynamic shared libraries are so easy to update compared to unshared or static shared libraries, it's easy to change libraries that are in use by existing programs, which means that the behavior of those programs changes even though "nothing has changed". | | | This is basically the static linked library approach from Chapter 9, except that in case of address space collisions, rather than the program failing the dynamic linker moves the libraries at some loss of performance. | | | Once it's found the file containing the library, the dynamic linker opens the file, and reads the ELF header to find the program header which in turn points to the file's segments including the dynamic segment. |

| | NSPR Reference: Chapter 22 Dynamic Library Linking |
| | To use the dynamic library loading functions on some platforms, certain environment variables must be set at run time, and you may need to link your executable programs using special linker options. | | | A static link table entry can be created by a client of the runtime so that other clients can access static or dynamic libraries transparently. | | | The dynamic library search path is the list of directories in which to look for a dynamic library. |

| | Dynamic Linking |
| | Otherwise, the dynamic linker evaluates procedure linkage table entries lazily, delaying symbol resolution and relocation until the first execution of a table entry. | | | The dynamic linker may choose different memory segment addresses for the same shared object in different programs; it may even choose different library addresses for different executions of the same program. | | | Although the absolute addresses are unknown when the link editor builds an object file, the dynamic linker knows the addresses of all memory segments and can thus calculate the absolute addresses of the symbols contained therein. |

| | CMSC 838Y Paper Reviews |
| | One of the key sticking points in the paper it seemed was a consideration of security; namely, that adding dynamic linking to a type-safe framework should only minimally add to the trusted code base (TCB), thereby reducing the likelyhood of security violations of the framework. | | | The goal of the paper is to build a system for provably correct type checked dynamic linking on top of Typed Assembly Language (TAL) while minimizing changes to the 'Trusted Computing Base'. | | | This paper described a methodology and an implementation for type safe dynamic linking of native code. |

| | Dynamic Linking |
| | The dynamic linker is permitted to evaluate procedure linkage table entries lazily, thus avoiding symbol resolution and relocation overhead for functions that are not called. | | | The dynamic linker must determine the pathname of the object containing this entry when the object is loaded. | | | When the dynamic linker creates the process image for an executable file or adds a shared object to the process image, it reads the relocation table and performs the associated actions. |

| | Dynamic Linking with ELF Object Files |
| | Linking calls to functions in the shared library represents a subset of the services that the simulator must perform to truly emulate dynamic linking. | | | A simulator that accepts binary object files as input must incorporate a technique for linking calls to functions that reside in a shared library. | | | To fully simulate an ELF binary, functionality for performing dynamic linking must be incorporated into the simulator. |

| | Building And Using Static And Shared "C" Libraries |
| | In order to fully understand the way linking is done, and be able to overcome linking problems, we should bare in mind that the order in which we present the object files and the libraries to the linker, is the order in which the linker links them into the resulting binary file. | | | For this reason, linking a program whose object files are ordered in libraries is faster than linking a program whose object files are separate on the disk. | | | However, the object files from the dynamic library are not inserted into the executable file. |

| | Dynamic Linking in Eiffel |
| | Although it is possible to use an interpretive representation for dynamic classes, it seems preferable for performance reasons to go to C in final mode. | | | Developers (the same as in previous steps, or others) write a Dynamic Class Set or DC-set, that is to say one or more classes which may only depend on each other and on classes in the DR-system. | | | In spite of their names DYNAMIC and YOUR_DYNAMIC are static classes since they are part of the DR-system at assembly time; they are static specifications of the minimum set of properties of dynamic classes. |

| | Kevin's computing glossary: dynamic linking |
| | Most modern computer systems favour the use of dynamic linking where possible. | | | The problem is that some software libraries are very large, and reproducing them in the memory space of every program that uses then is not a good use of memory. | | | In Windows systems, these files normally have names that end in `.DLL'; in Unix systems the convention is to use names that end in `.so.XXX' where XXX is the version number of the component. |

| | Dynamic Linking |
| | In contrast, dynamically linked executables are much smaller -- the linker just notes in the binary which shareable libraries were used to resolve which references, and leaves it at that. | | | When the binary is loaded for execution, the runtime linker looks for the shared libraries for which it finds references in the binary, and then does a `fixup' to resolve all the external references using the libraries. | | | What you save in link time during development and in disk space, you may pay for when waiting for the binary to load. |

| | Apache 1.3 Dynamic Shared Object (DSO) support |
| | On modern Unix derivatives there exists a nifty mechanism usually called dynamic linking/loading of Dynamic Shared Objects (DSO) which provides a way to build a piece of program code in a special format for loading it at run-time into the address space of an executable program. | | | As of 1998 there are only a few software packages available which use the DSO mechanism to actually extend their functionality at run-time: Perl 5 (via its XS mechanism and the DynaLoader module), Netscape Server, etc. | | | The executable program has no need to do anything on its own to use the symbols from the DSO because the complete resolving is done by the Unix loader. |
