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 5)

  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.
