CMake supports building executables, libraries (e.g. libxyz, xyz.dll etc.), object file libraries and pseudo-targets (including aliases). CMake can produce object files that can be linked against by executable binaries/libraries, avoiding dynamic (run-time) linking and using static (compile-time) linking instead.
When a linker links modules to create a shared library, it merges the GOTs and sets the final offsets in code. It is not necessary to adjust the offsets when loading the shared library later. [7] Position-independent functions accessing global data start by determining the absolute address of the GOT given their own current program counter value.
In a statically built program, no dynamic linking occurs: all the bindings have been done at compile time.. Static builds have a very predictable behavior (because they do not rely on the particular version of libraries available on the final system), and are commonly found in forensic and security tools to avoid possible contamination or malfunction due to broken libraries on the examined ...
A shared library or shared object is a computer file that contains executable code designed to be used by multiple computer programs or other libraries at runtime.. When running a program that is configured to use a shared library, the operating system loads the shared library from a file (other than the program's executable file) into memory at load time or runtime.
This allows the library files to be shared between many applications leading to space savings. It also allows the library to be updated to fix bugs and security flaws without updating the applications that use the library. In practice, many executables (especially those targeting Microsoft Windows) use both static and dynamic libraries.
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
A shared library or shared object is a file that is intended to be shared by executable files and further shared object files. Modules used by a program are loaded from individual shared objects into memory at load time or runtime , rather than being copied by a linker when it creates a single monolithic executable file for the program.
