(out-of-dir config/make not tested, and apr-iconv prolly needs some work) The buildconf scripts now generate a build-outputs.mk file which is included by the root's Makefile (via the build/gen-build.py script). bulid-outputs.mk specifies all of the various files present in the distribution. The top-level Makefiles were simplified to use an $(OBJECTS) symbol rather than 'find'ing them. Similarly, a $(HEADERS) symbol is used for the exports. The corresponding delete-* targets were eliminated since we have a precise set of inputs. The subdirs' Makefiles were removed since they are no longer called/used. The apr-util/uri Makefile was responsible for compiling a C program to generate the uri_delims.h file. That process was replaced by a Python script to generate the header (called by buildconf). The .c and .dsp were left for the Windows build to continue, but that should be revamped. build/apr_rules.mk was revamped somewhat to avoid recursion, but a lot of cleanup is still needed. Much of the recursive/local/x- logic is no longer needed and can be elimianated. rules.mk was created for inclusion by N makefiles, but that isn't really true any more, so it could probably be tossed (caveat: test/Makefile). Saved for a phase 2. Some additional work was added to properly clean up files in */build/, rather than relying on a makefile in there. git-svn-id: http://svn.apache.org/repos/asf/apr/apr/trunk@64891 13f79535-47bb-0310-9956-ffa450edef68
