README-pre-components:

---------------------

Current pre-components are langtools, jaxws, jaxp, and corba.

Pre-components can use ant to build but must have a make/Makefile for

building (a GNU make Makefile).

All ant knowledge is being isolated in the workspaces that use it.

Also for various reasons it is nice to have a Makefile wrapper over the

running of ant, but in general having to do

anything with shell commands is much easier to do in a Makefile

than in an ant script.

The make/makefile rules are:

Variables:

ALT_BOOTDIR The jdk home to use to build, if provided

ALT_LANGTOOLS_DIST The dist area from a langtools build to use, if provided

ALT_OUTPUTDIR Parent dir of build and dist directories, if provided

VARIANT If DBG, debug build, if OPT, optimized build

TARGET_CLASS_VERSION The classfile version number (currently 7)

ANT_HOME Home of ant to use, if provided

QUIET If defined, be quiet

VERBOSE If defined, be verbose

JDK_VERSION Version being built

FULL_VERSION Full version string for this jdk build

MILESTONE fcs, beta, internal or empty

BUILD_NUMBER Number of the jdk build

JPRT_ARCHIVE_BUNDLE Path to zip bundle to create for JPRT

Targets:

all Build everything, including dist

build Build build area

clean Clean up

clobber Same as clean (don't ask)

sanity Perform any sanity checks, exit non-zero if errors

jprt_build_product JPRT product build, zip results into JPRT_ARCHIVE_BUNDLE

jprt_build_debug JPRT debug build, zip results into JPRT_ARCHIVE_BUNDLE

jprt_build_fastdebug JPRT fastdebug build, zip results into JPRT_ARCHIVE_BUNDLE

Then of course we expect a dist/lib/classes.jar, dist/lib/src.zip and dist/lib/bin.zip.
