[-- Attachment #1 --] I don't have a wiki page. My initial success was in building the mercurial OpenJDK7 BSD-Port, using the attached build script and instructions obtained from the OpenJDK Wiki Darwin9Build (https://wiki.openjdk.java.net/display/BSDPort/Darwin9Build) section. Subsequently, I used information from the arm patch to modify the ports Makefile and build the ports distribution. Other than what's in the make file patch, no other patches were needed, as I used the mercurial build as the bootstrap. The key for non-x86 builds is the bootstrap. I used the GCC java tools and created a bootstrap (/usr/local/bootstrap-openjdk) using sym links to the GCC java executables in /usr/local/bin. I can provide more details if needed, however, building GCC java was not as straight forward as it is not a configurable option for non-x86 GCC builds. I had to modify the port Makefile.

That's fantastic! I'll try this soon on my G5. Do you have any wiki page with build steps, or even better a port change to add this to ports? - Justin [-- Attachment #2 --] --- ./Makefile +++ ./Makefile @@ -78,11 +78,12 @@ DOS2UNIX_FILES= jdk/src/share/classes/com/sun/org/apache/xml/internal/security/resource/xmlsecurity_en.properties -OPENJDK_OSARCH= bsd-${ARCH:S/i386/i586/} +OPENJDK_OSARCH= bsd-${ARCH:S/i386/x86/:S/amd64/x86_64/:S/armv6/arm/:S/powerpc64/powerpc/} NOPRECIOUSMAKEVARS= yes -ONLY_FOR_ARCHS= i386 amd64 +ONLY_FOR_ARCHS= i386 amd64 armv6 powerpc64 _MAKE_JOBS= # MAKE_ENV+= LANG="C" \ @@ -116,6 +117,23 @@ MAKE_ENV+= HOTSPOT_BUILD_JOBS=${MAKE_JOBS_NUMBER} .include <bsd.port.options.mk> +.if ${ARCH} == "armv6" +CONFIGURE_ARGS+= --with-jvm-variants=zero + +# we're building a zero build +JDK_BUILDDIR= ${WRKSRC}/build/${OPENJDK_OSARCH}-normal-zero-${JDK_BUILD_TYPE} + +# bootstrap-openjdk is based on openjdk7 and can compile openjdk8 +BOOTSTRAP_JDKS= ${LOCALBASE}/bootstrap-openjdk +BOOTSTRAPJDKDIR= ${LOCALBASE}/bootstrap-openjdk + +# libffi is needed for zerobuild +BUILD_DEPENDS+= ${BOOTSTRAPJDKDIR}/bin/javac:${PORTSDIR}/java/bootstrap-openjdk +LIB_DEPENDS+= libffi.so:${PORTSDIR}/devel/libffi +.endif + +.if ${ARCH} == "powerpc64" +CONFIGURE_ARGS+= --with-jvm-variants=zero + +# libffi is needed for zerobuild +BUILD_DEPENDS+= ${BOOTSTRAPJDKDIR}/bin/javac:${PORTSDIR}/java/bootstrap-openjdk +LIB_DEPENDS+= libffi.so:${PORTSDIR}/devel/libffi + +MAKE_ENV+= ZERO_BUILD=true \ + ZERO_ENDIANNESS=big \ + ZERO_LIBARCH=ppc \ + ZERO_ARCHDEF=PPC \ + ZERO_ARCHFLAG="-mpowerpc64" \ + PARALLEL_COMPILE_JOBS=8 + +.endif + BOOTSTRAP_JDKS= ${LOCALBASE}/openjdk7 \ ${LOCALBASE}/openjdk6 \ ${LOCALBASE}/bootstrap-openjdk @@ -143,7 +161,7 @@ # GCC is broken with PCH: https://lists.freebsd.org/pipermail/svn-src-all/2015-March/101722.html .if ${COMPILER_TYPE} == gcc -MAKE_ENV+= USE_PRECOMPILED_HEADER=0 +MAKE_ENV+= USE_PRECOMPILED_HEADER=1 .endif .if empty(ICONV_LIB) @@ -160,6 +178,34 @@ ${WRKSRC}/jdk/make/sun/splashscreen/Makefile \ ${WRKSRC}/jdk/make/java/npt/Makefile \ ${WRKSRC}/jdk/make/java/instrument/Makefile +.endif + +.if ${ARCH} == "armv6" || "powerpc64" + # From NetBSD http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/lang/openjdk7/hacks.mk + # Workaround incorrect constant folding of subnormals in javac when the FPU + # does not handle subnormal arithmetic, like on powerpc in Flush-to-zero mode. + # These workarounds avoid underflow conditions during the bootstrap so the + # JDK can correctly build itself.
