поддерживать, обновлять и восстанавливать группы программ (РАЗРАБОТКА) (maintain, update, and regenerate groups of programs (DEVELOPMENT))
Описание (Description)
The make utility shall update files that are derived from other
files. A typical case is one where object files are derived from
the corresponding source files. The make utility examines time
relationships and shall update those derived files (called
targets) that have modified times earlier than the modified times
of the files (called prerequisites) from which they are derived.
A description file (makefile) contains a description of the
relationships between files, and the commands that need to be
executed to update the targets to reflect changes in their
prerequisites. Each specification, or rule, shall consist of a
target, optional prerequisites, and optional commands to be
executed when a prerequisite is newer than the target. There are
two types of rule:
1. Inference rules, which have one target name with at least one
<period> ('.') and no <slash> ('/')
2. Target rules, which can have more than one target name
In addition, make shall have a collection of built-in macros and
inference rules that infer prerequisite relationships to simplify
maintenance of programs.
To receive exactly the behavior described in this section, the
user shall ensure that a portable makefile shall:
* Include the special target .POSIX
* Omit any special target reserved for implementations (a
leading period followed by uppercase letters) that has not
been specified by this section
The behavior of make is unspecified if either or both of these
conditions are not met.
