make
The make
utility automatically determines which pieces of a large
program need to be recompiled, and issues commands to recompile them.
This manual describes GNU make
, which was implemented by Richard
Stallman and Roland McGrath. Development since Version 3.76 has been
handled by Paul D. Smith.
GNU make
conforms to section 6.2 of IEEE Standard
1003.2-1992 (POSIX.2).
Our examples show C programs, since they are most common, but you can use
make
with any programming language whose compiler can be run with a
shell command. Indeed, make
is not limited to programs. You can
use it to describe any task where some files must be updated automatically
from others whenever the others change.
