This should make the discouraged use of + 'foo_SHORTNAME' unnecessary in many cases. + +* Bugs fixed: + + - Automatic dependency tracking has been fixed to work also when the + 'subdir-object' option is used and some 'foo_SOURCES' definition + contains unexpanded references to make variables, as in, e.g.: + + a_src = sources/libs/aaa + b_src = sources/bbb + foo_SOURCES = $(a_src)/bar.c $(b_src)/baz.c + + With such a setup, the created makefile fragment containing dependency + tracking information will be correctly placed under the directories + named 'sources/libs/aaa/.deps' and 'sources/bbb/.deps', rather than + mistakenly under directories named (literally!) '$(src_a)/.deps' and + '$(src_b)/.deps' (this was the first part of automake bug#13928). + + Notice that in order to fix this bug we had to slightly change the + semantics of how config.status bootstraps the makefile fragments + required for the dependency tracking to work: rather than attempting + to parse the Makefiles via grep and sed trickeries only, we actually + invoke 'make' on a slightly preprocessed version of those Makefiles, + using a private target that is only meant to bootstrap the required + makefile fragments. + + - The 'subdir-object' option no longer causes object files corresponding + to source files specified with an explicit '$(srcdir)' component to be + placed in the source tree rather than in the build tree. + + For example, if Makefile.am contains: + + AUTOMAKE_OPTIONS = subdir-objects + foo_SOURCES = $(srcdir)/foo.c $(srcdir)/s/bar.c $(top_srcdir)/baz.c + + then "make all" will create 'foo.o' and 's/bar.o' in $(builddir) rather + than in $(srcdir), and will create 'baz.o' in $(top_builddir) rather + than in $(top_srcdir). + + This was the second part of automake bug#13928. + + - Installed 'aclocal' m4 macros can now accept installation directories + containing '@' characters (automake bug#20903) + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New in 1.15.1: |
