automatic regeneration for all of this template substitution, and for
config.status etc. is done for you.
-Tables of file reference syntaxes
----------------------------------
-
-In a nonrecursive makefile supporting out of tree builds there are
-three separate important distinctions between different file
-locations:
-
- (i) In the build tree, or in the source tree ?
-
- (ii) In (or relative to) the subdirectory to which this Dir.sd.mk
- relates, or relative to the project's top level ?
-
- (iii) Absolute or relative pathname ? Usually relative pathnames
- suffice. Where an absolute pathname is needed, it can be built
- out of &/ and an appropriate make variable such as $(PWD).
-
-Path construction &-expansions are built from the following:
-
- Relative paths in...
- build source
-
- This directory & &^
- Top level . &~
-
-In more detail, with all the various options laid out:
-
- Recommended Relative paths in... Absolute paths in...
- for build source build source
-
- This lc &file &^file $(PWD)/&file $(abs_src)/&file
- directory any &/file &^/file $(PWD)/&/file $(abs_src)/&/file
- several & f g h &^ f g h $(addprefix...)
-
- Top lc file &~file
- level any file &~/file $(PWD)/file $(abs_src)/file
- .mk.in file $(src)/file $(PWD)/file $(abs_src)/file
- several f g h &~ f g h $(addprefix...)
