The command line syntax is cmake <dir> where <dir> is a directory that contains a CMakeLists.txt file. Then, the native build tools are invoked either via CMake (cmake --build <dir>) or directly via the native tool's interface. The native build tools use the generated files. [14] [32]
pkg-config is software development tool that queries information about libraries from a local, file-based database for the purpose of building a codebase that depends on them. . It allows for sharing a codebase in a cross-platform way by using host-specific library information that is stored outside of yet referenced by the codeba
It integrates with the Qt framework, and automates the creation of moc (meta object compiler) and rcc (resource compiler) sources, which are used in Qt's meta-object system and in the integration of binary resources (e.g. pictures). It has been deprecated by Qt Group in 2018 to redirect the resources to CMake instead "Deprecation of Qbs"..
PIE binaries are used in some security-focused Linux distributions to allow PaX or Exec Shield to use address space layout randomization (ASLR) to prevent attackers from knowing where existing executable code is during a security attack using exploits that rely on knowing the offset of the executable code in the binary, such as return-to-libc ...
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.
Binary compatibility is a major benefit when developing computer programs that are to be run on multiple OSes. Several Unix-based OSes, such as FreeBSD or NetBSD, offer binary compatibility with more popular OSes, such as Linux-derived ones, since most binary executables are not commonly distributed for such OSes.
CMake uses several Bison grammars. [12] GCC started out using Bison, but switched to a hand-written recursive-descent parser for C++ in 2004 (version 3.4), [13] and for C and Objective-C in 2006 (version 4.1) [14] The Go programming language (GC) used Bison, but switched to a hand-written scanner and parser in version 1.5. [15]
rPath provided a system inventory. This inventory described the desired state of every file, binary, application component, and software stack on every production system—with complete information about applied policies and dependencies—as version-controlled system manifests. These manifests were actionable models for managing the complete ...
