# This script is placed in ../davinci/sources/ and run from there.  See also:

# Works on JDK7 M3 (b59).

# The current version (1.2) may break your build.

# Kurt Miller, 6/16/2009:
# ALT_HOTSPOT_IMPORT_PATH, ALT_JDK_IMPORT_PATH should never be set
# when building the full bsd-port. This may be the source of the
# problem you are hitting.

# I also recommend that a controlled, clean environment be used
# to build bsd-port. For Apple something similar to this should be
# correct:

# env -i PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin \

This is the script I use to build mlvm, after cloning a source repo (from hotspot-comp) and applying mlvm patches (to jdk and hotspot sub-repos).
