If all you are working on is hotspot, you should be able to
use the hotspot/make/Makefile alone.
It will build hotspot and copy it into a jdk image for you.
Try 'make help'

Hello, guys
Recently, I am working on some slight modifications of Hotspot VM
without touching the JDK part. So, I have to compile Hotspot quite
frequently. However, the build is awfully slow on my machine with a
Intel 2.4G dual core CPU, 3G memory, and OpenSUSE11. It takes about 2-3
hours for one build.
Here is the relevant fragment of my build script:
==================================
export MAKE_VERBOSE=true
export DEBUG_GDB3=true
export ARCH_DATA_MODEL=32
export ALT_PARALLEL_COMPILE_JOBS=4
export HOTSPOT_BUILD_JOBS=4
export BUILD_HOTSPOT=true
export BUILD_LANGTOOLS=false
export BUILD_JDK=false
export BUILD_JAXP=false
export BUILD_JAXWS=false
export BUILD_CORBA=false
export BUILD_DEPLOY=false
export BUILD_J2SE=false
export DEV_ONLY=true
export SKIP_DEBUG_BUILD=false
export SKIP_FASTDEBUG_BUILD=true
==================================
Any ideas on how to tune this to speed up the build? Or, are there
problems with the script?
Thanks!
