Make
Make is a build automation tool that automatically builds arbitrary targets (in most cases program executables or libraries) from a list of prerequisites (which can be files or other targets). Make is controlled by reading files called Makefiles which specify how to derive the target. While make is a standard UNIX tool today in most cases people refer to the (GNU make https://www.gnu.org/software/make/) implementation which provides a lot of extensions.
The main benefits of using a build automation tool are:
- Automation :-) of repetitive command execution
- Consistent build results preventing errors
- Easier configuration for different tool chains
- Formulate complex build settings with possibly various targets from the same source tree
- Automatic matching of prerequisites
- Speed up compilation by rebuilding only changed source files targets and parallel build support
Any serious software development effort sooner or later has to use a automated build tool. While make is the standard build tool on Linux systems there are various alternatives available, sometimes standalone and sometimes as a frontend to make.
