| | Shared Libraries |
 | | Shared libraries (Shared objects) intend to save computing resources by sharing common code between users and applications. | | | define the library path via an adaptable variable environment setting which sets the order in which directories are searched for the shared libraries. | | | This will run 'shlib' to build a shared library for all packages in the test release, then do the standard shared linking procedure which is: linking shared libraries in the path first, followed by resolution of undefined symbols from static libraries. |

| | MkLinux Shared Library Support |
| | Another advantage of shared libraries is that when a library is updated, e.g., to fix a bug, all programs which use the library immediately enjoy the fix, without have to be rebuilt. | | | For a shared library, a single copy suffices; the same copy is referenced by each shared executable that uses the library. | | | The primary reason to use shared libraries is that you achieve a reduction in disk and memory use. |

| | shared libraries |
| | A shared library, or shared object file, or dynamic library, is a file in the ELF file format (see elf(3E)) that contains data and usually code that is needed by application binaries. | | | Changes in the implementation do not matter to programs using the library, so it is possible to, say, optimize the code in a library, thereby optimizing every program that uses the library, without changing the version number. | | | It, along with any other shared libraries an application binary depends on, is transparently loaded into memory when the binary is executed, making itself available to the binary. |

| | Shared Libraries |
| | The soname has the prefix ``lib'', the name of the library, the phrase ``.so'', followed by a period and a version number that is incremented whenever the interface changes (as a special exception, the lowest-level C libraries don't start with ``lib''). | | | Shared libraries are libraries that are loaded by programs when they start. | | | According to the FHS, most libraries should be installed in /usr/lib, but libraries required for startup should be in /lib and libraries that are not part of the system should be in /usr/local/lib. |

| | Ian Sharpe - Technical Notes - Shared Libraries & Ada |
| | Shared libraries are binary files containing code that is intended to be linked with executing processes at run-time rather than during the link phase of executable development. | | | As long as a mechanism exists to call shared library routines (and ensure that the structure of the passed data is correct) the programming language of the caller and the library is unimportant. | | | The difference is in the way in which the shared library is loaded rather than in the library itself. |

| | Shared Libraries without an MMU |
| | Each shared library can assume a virtual address for the location of its writable static data segment and the MMU can be programmed to map to a physical address that is only used by that process. | | | Even if shared libraries are not used, the text segments for programs are still shared; If multiple instances of a program are running, they would be running from the same text space. | | | Shared library functionality can also be provided without an MMU, but the implementation will be more complex and may have some limitations. |

| | [uClinux-dev] Shared libraries |
| | The only known restriction on shared libraries at this point is that the environ global variable will not be initialised until the main program has started its execution. | | | For n shared libraries there is an overhead of 4n+4 bytes per data segment and with up to n+1 data segments per application this quickly adds up. | | | A shared library can be constructed from any combination of object and library files with only a few restrictions. |

| | Shared Libraries on HP-UX |
| | A library is a file containing instructions and data that can be used by other programs. | | | One really useful feature is that source code in a library is shared among all processes that use that library. | | | Because NFS is used at DIII-D, you may sometimes have the case where a process is accessing the shared library on another host in the LSF cluster. |

| | Debian Policy Manual - Shared libraries |
| | If you have several shared libraries built from the same source tree you may lump them all together into a single shared library package, provided that you change all of their sonames at once (so that you don't get filename clashes if you try to install different versions of the combined shared libraries package). | | | system, which is very simple in its design: any package which provides a shared library also provides information on the package dependencies required to ensure the presence of this library, and any package which uses a shared library uses this information to determine the dependencies it requires. | | | If a package contains a binary or library which links to a shared library, we must ensure that when the package is installed on the system, all of the libraries needed are also installed. |

| | Writing shared libraries |
| | If your library now has an interface version of 1.1, that should be the version you use to advertise the software with. | | | For instance, a library with an interface version of 1.4 can satisfy the dependency of a program which requires version 1.2, but not one that requires 3.0 or 0.8. | | | Basically what this means is that if your library can run callbacks in user code, your library needs to be re-entrant: ie at any point at which you run a callback, execution can start again from the top of any of the library functions. |

| | 11 Shared Libraries |
| | This chapter describes the shared libraries both in UNIX (shared libraries) and in Windows (DLLs). | | | When the project is compiled, the methods in modules in the dyn_libs libraries appear as "unregistered." When you run a project executable in which AVS/Express encounters unregistered methods in libraries for which the dyn_libs property is set, AVS/Express uses the library path variable to look for the methods. | | | Within AVS/Express itself, the W3C (Web) library (Read_URL, ReadWebField and ReadWebGeom macros) and the Read/Write image libraries are implemented as DLL libraries that share express.dll with the main executable. |

| | Building Shared Libraries |
| | This shouldn't be used if you are distributing binaries, and people won't have a copy of the library on their computer. | | | However, if you are using ELF, you can easily make shared libraries, so each binary you link against your library doesn't keep it's own copy of all the code - resulting in smaller binaries. | | | To make an archive library, you use the archiver, of course (:-). |

| | Shared Libraries Considered Harmful |
| | And any issues of version conflicts at the protocol level are precisely the same whether you use shared libraries or not, as are the solutions to those issues. | | | The first client of the protocol to start up creates a shared structure (memory block, pipe, mailbox, event queue or whatever) to be used for the inter-process communication. | | | To add to the fun, replace the phrase "existing applications" above with "code in other shared libraries". |

| | The library manager understands this chunk when it loads an AOF, and will ensure that those libraries are installed with the file. | | | If we don't select a single base library now, developers would have to provide two (or more) versions of each of their libraries, and it would be a nightmare! | | | We might also want to incorporate the major version number into the library's name — it has to match exactly, just like the name, and it would save a directory level storing the library. |
