========
|
|
|
|
*dumbmake* is a simple dependency tracker for make.
|
|
|
|
It turns lists of make targets into longer lists of make targets that
|
|
include dependencies. For example:
|
|
|
|
netwerk, package
|
|
|
|
might be turned into
|
|
|
|
netwerk, netwerk/build, toolkit/library, package
|
|
|
|
The dependency list is read from the plain text file
|
|
`topsrcdir/build/dumbmake-dependencies`. The format best described by
|
|
example:
|
|
|
|
build_this
|
|
when_this_changes
|
|
|
|
Interpret this to mean that `build_this` is a dependency of
|
|
`when_this_changes`. More formally, a line (CHILD) indented more than
|
|
the preceding line (PARENT) means that CHILD should trigger building
|
|
PARENT. That is, building CHILD will trigger building first CHILD and
|
|
then PARENT.
|
|
|
|
This structure is recursive:
|
|
|
|
build_this_when_either_change
|
|
build_this_only_when
|
|
this_changes
|
|
|
|
This means that `build_this_when_either_change` is a dependency of
|
|
`build_this_only_when` and `this_changes`, and `build_this_only_when`
|
|
is a dependency of `this_changes`. Building `this_changes` will build
|
|
first `this_changes`, then `build_this_only_when`, and finally
|
|
`build_this_when_either_change`.
