 # 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.

 # No tests on Aix.
