 # The complexity of this makefile is not the fault of make, but the fault

 # of javac and javah. The basic problems are:

 #

 #    1) Compiling a single Java source file unpredictably generates anything

 #       between zero (0!) and an infinite number of .class files!

 #    2) There is no hint, for which classes javah needs to be run,

 #       and it happily generates .h files for classes with no native methods.

 #    3) javac and javah do not cleanup anything, for example if an internal

 #       class (potentially with native methods) is removed from a Java source file.

 #

 # This makefile is a tribute to GNU make. And yes, it was harder to write than it is

 # to read. The include/excludes of directories and files are only a temporary measure

 # to work around the messy jdk sources that put platform specific code in src/share/classes.

 #

 # We should move most of the functionality of this makefile into a

 # smart javac/javah/javadoc/jar combo tool. sjavac ?

 #

 # I.e. 1) It always generates a single output, a zip-file from a number of source roots.

 #         The zip file contains information that enable incremental builds with full 

 #         dependency tracking between packages.

 #      2) It automatically generates the right .h files.

 #      3) It keeps its house clean.

 #      *) Generates intermediate files to be used for javadoc generation later.

 #      and does all the other useful things that this makefile does, such as:

 #          use all cores for compilation, reuse the running JVM for all compilations,

 #          and has pubapi dependency tracking to minimize the number of files

 #          that need to be recompiled during an incremental build.

 # 

 # A zip file, or several zip files combined, can then be converted to a .jar file, or to a .jmod file.

 #

 # This would make this makefile much much simpler. I.e. make can be used

 # for its real purpose, track dependencies and trigger a recompile if a

 # dependency has changed.

 #

 # When you read this source. Remember that $(sort ...) has the side effect

 # of removing duplicates. It is actually this side effect that is

 # desired whenever sort is used below!
