I followed instructions from http://wikis.sun.com/display/OpenJDK/Darwin10Build
I am using 64-bit soylatte and running on 64-bit 10.6.4. I get the following errors: cd /Users/aruld/bsd-port/hotspot/make; \ make VM_TARGET=product1 generic_build1 ALT_OUTPUTDIR=/Users/aruld/bsd-port/build/bsd-amd64/hotspot/outputdir Makefile:336: target `/Xusage.txt' given more than once in the same rule. mkdir -p /Users/aruld/bsd-port/build/bsd-amd64/hotspot/outputdir *No compiler1 (product1) for ARCH_DATA_MODEL=64* cd /Users/aruld/bsd-port/hotspot/make; \ make VM_TARGET=productkernel generic_buildkernel ALT_OUTPUTDIR=/Users/aruld/bsd-port/build/bsd-amd64/hotspot/outputdir Makefile:336: target `/Xusage.txt' given more than once in the same rule. mkdir -p /Users/aruld/bsd-port/build/bsd-amd64/hotspot/outputdir No kernel (productkernel) for OS_NAME=bsd cd /Users/aruld/bsd-port/build/bsd-amd64/hotspot/outputdir; \ make -f /Users/aruld/bsd-port/hotspot/make/bsd/Makefile \ JAVA_HOME=/Users/aruld/soylatte16-amd64-1.0.3 OUTPUTDIR=/Users/aruld/bsd-port/build/bsd-amd64/hotspot/outputdir GAMMADIR=/Users/aruld/bsd-port/hotspot MAKE_VERBOSE=y HOTSPOT_RELEASE_VERSION=19.0-b05 JRE_RELEASE_VERSION=1.7.0-internal-aruld_2010_10_07_15_06-b00 HOTSPOT_BUILD_VERSION= docs /Users/aruld/soylatte16-amd64-1.0.3/bin/javap javax.xml.transform.TransformerFactory > /dev/null 2>&1; \ if [ $? -ne 0 ]; then \ /Users/aruld/soylatte16-amd64-1.0.3/bin/java -version; \ echo "*** An XSLT processor (J2SE 1.4.x or newer) is required" \ "to bootstrap this build" 1>&2; \ exit 1; \ fi mkdir -p bsd_amd64_docs make -f /Users/aruld/bsd-port/hotspot/make/bsd/makefiles/jvmti.make " LP64=1 " GAMMADIR=/Users/aruld/bsd-port/hotspot OS_FAMILY=bsd ARCH=x86 BUILDARCH=amd64 LIBARCH=amd64 HOTSPOT_RELEASE_VERSION=19.0-b05 HOTSPOT_BUILD_VERSION= JRE_RELEASE_VERSION=1.7.0-internal-arul_2010_10_07_15_06-b00 JvmtiOutDir=bsd_amd64_docs jvmtidocs /Users/aruld/soylatte16-amd64-1.0.3/bin/javac -g -encoding ascii -source 6 -target 6 -d bsd_amd64_docs /Users/aruld/bsd-port/hotspot/src/share/vm/prims/jvmtiGen.java Generating bsd_amd64_docs/jvmti.html /Users/aruld/soylatte16-amd64-1.0.3/bin/java -classpath bsd_amd64_docs jvmtiGen -IN /Users/aruld/bsd-port/hotspot/src/share/vm/prims/jvmti.xml -XSL /Users/aruld/bsd-port/hotspot/src/share/vm/prims/jvmti.xsl -OUT bsd_amd64_docs/jvmti.html make VM_SUBDIR=product generic_export Makefile:336: target `/Xusage.txt' given more than once in the same rule. make[3]: *** No rule to make target `/Users/aruld/bsd-port/build/bsd-amd64/hotspot/import/docs/platform/jvmti/jvmti.html', needed by `generic_export'.

Appreciate any directions. -Arul
