# Makefile for building sunec.jar and sunec native library.

#

# This file was derived from make/com/sun/crypto/provider/Makefile.

#

#

# (The terms "OpenJDK" and "JDK" below refer to OpenJDK and Sun JDK builds

# respectively.)

#

# JCE builds are very different between OpenJDK and JDK.  The OpenJDK JCE

# jar files do not require signing, but those for JDK do.  If an unsigned

# jar file is installed into JDK, things will break when the crypto

# routines are called.

#

# This Makefile does the "real" build of the JCE files.  For OpenJDK,

# the jar files built here are installed directly into the OpenJDK.

#

# For JDK, the binaries use pre-built/pre-signed binary files stored in

# the closed workspace that are not shipped in the OpenJDK workspaces.

# We still build the JDK files here to verify the files compile, and in

# preparation for possible signing.  Developers working on JCE in JDK

# must sign the JCE files before testing.  The JCE signing key is kept

# separate from the JDK workspace to prevent its disclosure.

#

# SPECIAL NOTE TO JCE/JDK developers:  The source files must eventually

# be built, signed, and then the resulting jar files MUST BE CHECKED

# INTO THE CLOSED PART OF THE WORKSPACE*.  This separate step *MUST NOT

# BE FORGOTTEN*, otherwise a bug fixed in the source code will not be

# reflected in the shipped binaries.  The "release" target should be

# used to generate the required files.

#

# There are a number of targets to help both JDK/OpenJDK developers.

#

# Main Targets (JDK/OPENJDK):

#

#     all/clobber/clean		The usual, plus the native libraries.

#				    If OpenJDK, installs sunec.jar.

#				    If JDK, installs prebuilt

#				    sunec.jar.

#

#     jar			Builds/installs sunec.jar

#				    If OpenJDK, does not sign.

#				    If JDK, tries to sign.

#

# Other lesser-used Targets (JDK/OPENJDK):

#

#     build-jar			Builds sunec.jar

#				    (does not sign/install)

#

#     install-jar		Alias for "jar" above.

#

# Other targets (JDK only):

#

#     sign			Alias for sign-jar

#	  sign-jar		Builds/signs sunec.jar (no install)

#

#     release			Builds all targets in preparation

#				for workspace integration.

#

#     install-prebuilt		Installs the pre-built jar files

#

# This makefile was written to support parallel target execution.
