A makefile can define and use macros. Macros are usually referred to as variables when they hold simple string definitions, like CC = clang. Macros in makefiles may be overridden in the command-line arguments passed to the Make utility. Environment variables are also available as macros.
qmake is a software build automation tool that generates makefiles for building a codebase. As it generates configuration files for other build tools, it is classified as a meta-build tool. The makefiles that qmake produces are tailored to the particular platform where it is run from based on qmake project files.
Buildroot is a set of Makefiles and patches that simplifies and automates the process of building a complete and bootable Linux environment for an embedded system, while using cross-compilation to allow building for multiple target platforms on a single Linux-based development system.
Much modern source code uses "conditional compilation" to control which part of the source code to be used based on C pre-processor symbols defined by the compiler. These symbols may state the compiler name or family, version number, operating system, and word size. Depending on these symbols, the included files may change.
The other tools are responsible for more directly building; using the generated files. A single set of CMake-specific configuration files can be used to build a codebase using the native build tools of multiple platforms. [4] Notable native build tools supported by CMake include: Make, Qt Creator, Ninja, Android Studio, Xcode, and Visual Studio ...
Boost boost.build – For C++ projects, cross-platform, based on Perforce Jam; Buck – Build system developed and used by Meta Platforms; written in Rust, using Starlark (BUILD file syntax) as Bazel; Buildout – programming tool aimed to assist with deploying software; Python-based
The generated "Makefile.in"s are portable and compliant with the Makefile conventions in the GNU Coding Standards, and may be used by configure scripts to generate a working Makefile. [2] The Free Software Foundation maintains automake as one of the GNU programs, and as part of the GNU build system.
The data type used for communication, YYSTYPE, is set using Bison %union declaration. Since in this sample we use the reentrant version of both flex and yacc we are forced to provide parameters for the yylex function, when called from yyparse. [23] This is done through Bison %lex-param and %parse-param declarations. [24]
