Dilbert, have you unzipped the debug info files (i.e. libjvm.diz)?
You have to manually do this, before you can debug with debugging symbols

Once again thanks to this blog along with other resources from the net, I have been able to write a new blog focussing on building Hotspot on Eclipse Juno under Ubuntu 12.04 using the new build-infra system: https://neomatrix369.wordpress.com/2013/03/12/hotspot-is-in-focus-again-aka-hacking-hotspot-in-eclipse-juno-under-ubuntu-12-04/, have a look comments and feedback are always welcome!

Thanks.

Thank you very much ! The new zero-build-infro/jdk patches works well.
But i can’t debug the interpreter code using gdb (no debugging symbols found…) even I configured with slowdebug,did i miss something? build-infra bug?

Unfortunately, yes. I tried a couple of times to get somebody from Oracle to commit and push them, but they did not seem responsive. *However* those jdk patches are obsolete by now and superseded by the new build system, for which patches are on their way:

Hi Roman, the jdk patches are still missing now?

Ok success with X32/Shark note that its a x86_64 system with 32bit ELF

There is a small patch needed that you could look at
jdk/makefiles/CreateJars.gmk

JARS += $(IMAGES_OUTPUTDIR)/lib/sa-jdi.jar

should be ifdef/endif inside ifeq ($(INCLUDE_SA), true)

without this patch images cant be built

file ./jdk/bin/java;./jdk/bin/java -version
./jdk/bin/java: ELF 32-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 3.4.0, not stripped
openjdk version “1.8.0-internal”
OpenJDK Runtime Environment (build 1.8.0-internal-root_2013_02_11_14_42-b00)
OpenJDK Shark VM (build 25.0-b19, mixed mode)

Thank you for the link ive got it working and running.however been a strict adherent to the klingon school of programinig i ignored your script and tried to use the new autotools with limited success they do not setup the enviroment correctly setting MFLAGS does work fine.

Should i have some time id like to work on this. i may also clean up the patch on bugzilla for shark/llvm with min 3.2 its clear llvm3.0/3.1 are lemons.

Your project is exactly what we’ve been looking for!
What do you think, needs to be changed for a MS Windows port. I am currently stuck in the makefile: WebSurfaceData.o cannot be found :/ I think a straight way is not that easy, huh?
