NAME

make — maintain program-generated and interdependent ﬁles

SYNOPSIS

make [–EeinpqrstuVvx][–k|–S][–c dir][–f ﬁle] ...

[macro deﬁnition] ... [target ...]

DESCRIPTION

make is a command that helps you manage projects that contain a set of interdependent ﬁles.

Typical examples would be a program with many source and object ﬁles, or a document that is

built from source ﬁles, macro ﬁles, and so on. make keeps all the ﬁles up-to-date with one

another: if one ﬁle changes, make updates all the other ﬁles that depend on the changed ﬁle.

Note: This implementation of make features the .POSIX special target to provide maximum

portability. When you specify this target, make processes the makeﬁle as speciﬁed in the

POSIX.2 standard. For details, see the description of .POSIX in the Special Targets section of

this man page.

Options

make accepts the following options:

–c dir attempts to change into the speciﬁed directory when make starts up. If make can’t

change directory, an error message is displayed. This is useful for recursive makeﬁles

when building in a different directory.

–E suppresses reading of the environment. If neither –E nor –e are speciﬁed, make

reads the environment before reading the makeﬁle.

–e reads the environment after reading the makeﬁle. If neither –E nor –e are speciﬁed,

make reads the environment before reading the makeﬁle.

–f ﬁle uses ﬁle as the source for the makeﬁle description. make ignores the makeﬁles

speciﬁed as prerequisites to the .MAKEFILES target. If you specify ﬁle as –, make

reads the standard input.

–i ignores all errors and continues making other targets. This is equivalent to the

.IGNORE attribute or macro.

–k makes all independent targets, even if an error occurs. Specifying –k tells make to

ignore the error and continue to make as much as possible. make does not attempt to

update anything that depends on the target that was being made when the error

occurred.

–n displays the commands that make would execute to update the chosen targets, but

does not actually execute the commands unless they have a plus sign (+) preﬁx.

When this option is speciﬁed, make displays lines with an at sign (@) preﬁx on the
