Building the Hotspot compiler team's Hotspot branch alone
| #!/bin/sh | |
| # This script is for building the hsx/hotspot-comp branch in isolation. | |
| # | |
| # Prerequisites: | |
| # * appropriate build tools | |
| # * a working Sun Java 6 build (i.e. JDK6) is available at: | |
| # HOME/java/re/j2se/1.6.0/latest/binaries/linux-[i586/amd64] | |
| # * a working Sun Java 7 build (i.e. JDK7) is available at: | |
| # HOME/java/re/j2se/1.7.0/latest/binaries/linux-[i586/amd64] | |
| # HOME/java/re/j2se/1.7.0/promoted/latest/binaries/linux-[i586/amd64] | |
| # HOME/java/re/jdk/7/latest/binaries/linux-[i586/amd64] | |
| # (symlinks are ok here) | |
| # * Hotspot compiler team branch checked out: | |
| # hg clone http://hg.openjdk.java.net/hsx/hotspot-comp/hotspot [dirname] | |
| # | |
| # Usage: | |
| # (from within checked-out dir) | |
| # sh ./build.sh help # for build help | |
| # sh ./build.sh docs # run this once before create_jdk | |
| # sh ./build.sh product # to build "product" hotspot | |
| # sh ./build.sh create_jdk # to create a new jdk based on JDK7 and this build | |
| # sh ./build.sh update_jdk # update already-assembled JDK with new hotspot build | |
| # The _jdk targets will deposit a full JDK environment under: | |
| # build/linux/jdk-linux-[i586/amd64] | |
| export ALT_SLASH_JAVA=${HOME}/java | |
| export HOTSPOT_BUILD_JOBS=2 | |
| export LANG=C | |
| # this should be 32 or 64 depending on which arch you want | |
| export ARCH_DATA_MODEL=64 | |
| make -C make $@ |
