# 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.

# 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. libsaproc[_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.

# The following renders pathnames in generated Makefiles valid on
# machines other than the machine containing the build tree.
#
# For example, let's say my build tree lives on /files12 on
# exact.east.sun.com.  This logic will cause GAMMADIR to begin with
# /net/exact/files12/...
#
# We only do this on SunOS variants, for a couple of reasons:
#  * It is extremely rare that source trees exist on other systems
#  * It has been claimed that the Linux automounter is flakey, so
#    changing GAMMADIR in a way that exercises the automounter could
#    prove to be a source of unreliability in the build process.
# Obviously, this Makefile is only relevant on SunOS boxes to begin
# with, but the SunOS conditionalization will make it easier to
# combine Makefiles in the future (assuming we ever do that).
