# 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 built before building libjvm.so

#                        Please refer to ./makefiles/sa.make

#  2. libsa.so         - Native library for SA - This is built after

#                        libjsig.so (signal interposition library)

#                        Please refer to ./makefiles/vm.make

# If $(GAMMADIR)/agent dir is not present, SA components are not built.
