# This makefile creates a build tree and lights off a build.
# You can go back into the build tree and perform rebuilds or
# incremental builds as desired. Be sure to reestablish
# environment variable settings for LD_LIBRARY_PATH and JAVA_HOME.

# The make process now relies on java and javac. These can be
# specified either implicitly on the PATH, by setting the
# (JDK-inherited) ALT_BOOTDIR environment variable to full path to a
# JDK in which bin/java and bin/javac are present and working (e.g.,
# /usr/local/java/jdk1.3/solaris), or via the (JDK-inherited)
# default BOOTDIR path value. Note that one of ALT_BOOTDIR
# or BOOTDIR has to be set. We do *not* search javac, javah, rmic etc.
# from the PATH.
#
# One can set ALT_BOOTDIR or BOOTDIR to point to a jdk that runs on
# an architecture that differs from the target architecture, as long
# as the bootstrap jdk runs under the same flavor of OS as the target
# (i.e., if the target is linux, point to a jdk that runs on a linux
# box).  In order to use such a bootstrap jdk, set the make variable
# REMOTE to the desired remote command mechanism, e.g.,
#
#    make REMOTE="rsh -l me myotherlinuxbox"

# Along with VM, Serviceability Agent (SA) is built for SA/JDI binding.
# JDI binding on SA produces two binaries:
#  1. sa-jdi.jar       - This is build before building libjvm[_g].so
#                        Please refer to ./makefiles/sa.make
#  2. libsa[_g].so     - Native library for SA - This is built after
#                        libjsig[_g].so (signal interposition library)
#                        Please refer to ./makefiles/vm.make
# If $(GAMMADIR)/agent dir is not present, SA components are not built.
