# Makefile for building ucrypto.jar and its native libraries.
#
# This file was modified from make/sun/security/pkcs11/Makefile.
#
#
# (The terms "OpenJDK" and "JDK" below refer to OpenJDK and Oracle
# JDK builds respectively.)
#
# This Makefile does the "real" build of the Ucrypto provider files.
# Since the sources are unavailable for OpenJDK, this Makefile is only
# useful for JDK.
#
#
# Main Targets (JDK on Solaris):
#
# all The usual, ucrypto.jar plus the native libraries.
# builds and installs the prebuilt/signed jar.
#
# clobber/clean Cleans up the temp directory, ucrypto.jar, the
# native libraries, and the config file from the
# build area
#
# jar Builds, signs and installs ucrypto.jar
# (Can only be done on machines with access to
# the signing keystore)
#
# Other lesser-used Targets (JDK on Solaris):
#
# build-jar Builds ucrypto.jar (no sign/install)
#
# sign Builds/signs ucrypto.jar (no install)
#
# release Builds all targets in preparation
# for workspace integration.
# (Can only be done on machines with access to
# the signing keystore)
#
# install-prebuilt Installs the pre-built jar files
#
# NOTE: None of the above target will update the prebuilt provider binary
# under the closed workspace. To update it, you must explicitly copy the
# binary from either the tmp/signed or lib/ext directory.
#
# This makefile was written to support parallel target execution.
