Macros in makefiles may be overridden in the command-line arguments passed to the Make utility. Environment variables are also available as macros. For example, the macro CC is frequently used in makefiles to refer to the location of a C compiler. If used consistently throughout the makefile, then the compiler used can be changed by changing ...
MAKE is an utility helping to serialized shell commands while stating the pre-required elements for each of these commands. As such, running a well conceived makefile allow to reproduce a complexe tree-like network of commands, in the right order, despite several starting points and bricks required for a final output or group of outputs.
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.
Despite being a simple design, make menuconfig offers considerable advantages to the question-and-answer-based configuration tool make config, the most notable being a basic search system and the ability to load and save files with filenames different from ".config".
The configure script, when run, scans the build environment and generates a subordinate config.status script which, in turn, converts other input files and most commonly Makefile.in into output files (Makefile), which are appropriate for that build environment. Finally, the make program uses Makefile to generate executable programs from source ...
If they are not specified in the Makefile, then they will be read from the environment, if present. Tools like autoconf's ./configure script will usually pick them up from the environment and write them into the generated Makefiles. Some package install scripts, like SDL, allow CFLAGS settings to override their normal settings (instead of ...

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.
