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.
Similarly, a variable CPPFLAGS exists with switches to be passed to the C or C++ preprocessor. Similarly, FFLAGS enables the addition of switches for a Fortran compiler. These variables are most commonly used to specify optimization or debugging switches to a compiler, as for example -g , -O2 or ( GCC -specific) -march=athlon .
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.
CMake uses a particular generator by default for the host environment. Alternatively, a generator can be selected via the command line option -G. For example, generator Unix Makefiles creates files for make. [4] CMake does not support custom generators without modifying the CMake implementation.
The choice of a variable name should be mnemonic — that is, designed to indicate to the casual observer the intent of its use. One-character variable names should be avoided except for temporary "throwaway" variables. Common names for temporary variables are i, j, k, m, and n for integers; c, d, and e for characters. int i;
makedepend is invoked with a list of sourcefiles: . makedepend [options] foo.c bar.c ... However, it is more often invoked as a target from a makefile, typically under the depend target, such that make depend will invoke makedepend on all source files in the project.
Different command-line argument parsing methods are used by different programming ... JavaScript programs written for Node.js use the process.argv global variable.
Ninja is a build system developed by Evan Martin, [4] a Google employee. Ninja has a focus on speed and it differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.
