1 README-pre-components:
   2 ---------------------
   3 Current pre-components are bdb, langtools, jaxws, jaxp, and corba.
   4 
   5 Pre-components can use ant to build but must have a make/Makefile for
   6 building (a GNU make Makefile).
   7 All ant knowledge is being isolated in the workspaces that use it.
   8 
   9 Also for various reasons it is nice to have a Makefile wrapper over the
  10 running of ant, but in general having to do
  11 anything with shell commands is much easier to do in a Makefile
  12 than in an ant script.
  13 
  14 The make/makefile rules are:
  15 
  16  Variables:
  17   ALT_BOOTDIR           The jdk home to use to build, if provided
  18   ALT_LANGTOOLS_DIST    The dist area from a langtools build to use, if provided
  19   ALT_OUTPUTDIR         Parent dir of build and dist directories, if provided
  20   VARIANT               If DBG, debug build, if OPT, optimized build
  21   TARGET_CLASS_VERSION  The classfile version number (currently 7)
  22   ANT_HOME              Home of ant to use, if provided
  23   QUIET                 If defined, be quiet
  24   VERBOSE               If defined, be verbose
  25   JDK_VERSION           Version being built
  26   FULL_VERSION          Full version string for this jdk build
  27   MILESTONE             fcs, beta, internal or empty
  28   BUILD_NUMBER          Number of the jdk build
  29   JPRT_ARCHIVE_BUNDLE   Path to zip bundle to create for JPRT
  30 
  31  Targets:
  32   all                   Build everything, including dist
  33   build                 Build build area
  34   clean                 Clean up
  35   clobber               Same as clean (don't ask)
  36   sanity                Perform any sanity checks, exit non-zero if errors
  37   jprt_build_product    JPRT product build, zip results into JPRT_ARCHIVE_BUNDLE
  38   jprt_build_debug      JPRT debug build, zip results into JPRT_ARCHIVE_BUNDLE
  39   jprt_build_fastdebug  JPRT fastdebug build, zip results into JPRT_ARCHIVE_BUNDLE
  40 
  41 Then of course we expect a dist/lib/classes.jar, dist/lib/src.zip and dist/lib/bin.zip.
