26 # The complexity of this makefile is not the fault of make, but the fault
27 # of javac and javah. The basic problems are:
28 #
29 # 1) Compiling a single Java source file unpredictably generates anything
30 # between zero (0!) and an infinite number of .class files!
31 # 2) There is no hint, for which classes javah needs to be run,
32 # and it happily generates .h files for classes with no native methods.
33 # 3) javac and javah do not cleanup anything, for example if an internal
34 # class (potentially with native methods) is removed from a Java source file.
35 #
36 # This makefile is a tribute to GNU make. And yes, it was harder to write than it is
37 # to read. The include/excludes of directories and files are only a temporary measure
38 # to work around the messy jdk sources that put platform specific code in src/share/classes.
39 #
40 # We should move most of the functionality of this makefile into a
41 # smart javac/javah/javadoc/jar combo tool. sjavac ?
42 #
43 # I.e. 1) It always generates a single output, a zip-file from a number of source roots.
44 # The zip file contains information that enable incremental builds with full
45 # dependency tracking between packages.
46 # 2) It automatically generates the right .h files.
47 # 3) It keeps its house clean.
48 # *) Generates intermediate files to be used for javadoc generation later.
49 # and does all the other useful things that this makefile does, such as:
50 # use all cores for compilation, reuse the running JVM for all compilations,
51 # and has pubapi dependency tracking to minimize the number of files
52 # that need to be recompiled during an incremental build.
53 #
54 # A zip file, or several zip files combined, can then be converted to a .jar file, or to a .jmod file.
55 #
56 # This would make this makefile much much simpler. I.e. make can be used
57 # for its real purpose, track dependencies and trigger a recompile if a
58 # dependency has changed.
59 #
60 # When you read this source. Remember that $(sort ...) has the side effect
61 # of removing duplicates. It is actually this side effect that is
62 # desired whenever sort is used below!
