build: don't hardcode repeated long paths in Makefile rules.
According to the DRY principle, scattering several copies of something across a file or project leads to pain. Let's not do that! * Makefile.am (Makefile_in, Makefile_inc, defs_in, defs_m4sh), (libtoolize_in, ltmain_m4sh, ltversion_in): New variables to hold the location of important files and targets. (EXTRA_DIST): Add the distributed ones by variable. (libtoolize, libltdl/Makefile.am, libltdl/m4/ltversion.m4) (libltdl/config/ltmain.sh, libltdl/stamp-mk, tests/defs) (tests/defs.in): Use the new variables to reduce noise and repetition.

build: don't hardcode repeated long paths in Makefile rules.
|
||||
According to the DRY principle, scattering several copies of
|
||||
something across a file or project leads to pain. Let's not
|
||||
do that!
|
||||
* Makefile.am (Makefile_in, Makefile_inc, defs_in, defs_m4sh),
|
||||
(libtoolize_in, ltmain_m4sh, ltversion_in): New variables to
|
||||
hold the location of important files and targets.
|
||||
(EXTRA_DIST): Add the distributed ones by variable.
|
||||
(libtoolize, libltdl/Makefile.am, libltdl/m4/ltversion.m4)
|
||||
(libltdl/config/ltmain.sh, libltdl/stamp-mk, tests/defs)
|
||||
(tests/defs.in): Use the new variables to reduce noise and
|
||||
repetition.
|
||||
|
||||
build: make better use of automatic variables in `Makefile.am'.
|
||||
* Makefile.am (libtoolize, libtoolize.in, libltdl/Makefile.am)
|
