similar to: [LLVMdev] [VMKit] 2.9 or ToT? Java version/features?

Hi Nicolas, Reviving old thread of sorts... thank you very much for your earlier response--I apologize for not responding to tell you how very helpful your information was! Didn't come back because you gave me everything I needed at the time :).

Hi, I see that now vmkit2 contains the last revisions of the project, so I follow these instructions to compile vmkit : http://vmkit2.gforge.inria.fr/start.php I download and compile LLVM without errors. I have tested with and without optimizations but this is the same for the errors. My configuration for LLVM is just : ./configure; make Apparently we can build vmkit with OpenJDK instead of GNU

Hi Julien, Due to some new commits, openjdk build is broken for the moment. We are fixing this. You can temporarily use the following commit to try VMKit with OpenJDK implementation. d9bf3794d66a116999f8f16d0799fba6fe5bd822 just call the following command in your vmkit directory: git checkout d9bf3794d66a116999f8f16d0799fba6fe5bd822 Harris Bakiras On 03/18/2013 10:12 AM, Julien Pagès

Hmm, disregard my previous comment (while you might still have issues with 64bit, that's not what's primarily causing your issue)--your particular error is when you don't point vmkit to the classpath libraries properly. Set it with the configure option --with-gnu-classpath-glibj=/path/to/classpath-0.97.2/lib/glibj.zip Good luck! ~Will On Tue, Aug 23, 2011 at 5:49 PM, Will Dietz

Ah yes, thanks, this was one problem, now I hit another: llvm[2]: Building Release+Asserts mmtk-vmkit.jar all Thread 0x110000000 received a SIGSEGV: either the VM code or an external native method is bogus.

Hi Harris Bakiras, Thanks for reply. It working now. Actually I wanted to try vmkit VM to run jruby codes. vmkit is able to run Java program, but when I try to run JRuby code then I get following error - root at komal:/home/komal/Desktop/GSOC/programs# jruby hello.rb > > Platform.java:39:in `getPackageName': java.lang.NullPointerException > > from ConstantSet.java:84:in

I am working on a project to port JRuby on Embedded systems. JRuby converts Ruby code to bytecode which is executed by any JVM. For this project I am testing performance of JRuby with various available JVMs. I have chosen ARM architecture. Does vmkit support ARM architecture?

here <http://vmkit.llvm.org/> its mentioned that its portable on ARM. So simply cross-compiling will work?

I don't know how JRuby works, maybe it uses some new feature that GNU Classpath does not provide. VMKit's openJDK version is unstable on 64 bits since package version 6b27. You can still use it for very small programs which does not need GC but that's all. It works fine on 32 bits. So you can try it on 32 bits or revert your java version to a previous one (< than 6b27) to test

Hello Kumar, Unfortunately we never experienced on ARM architecture and we are not planning to port VMKit on ARM for the moment.

Hi Kumar, It's a mistake, we will correct that, we haven't tested vmkit on arm. As LLVM supports arm, by cross-compiling vmkit in arm/linux, it could work, but you will probably have to adapt some few parts of the code. If you plan to make the port, feel free to send us a lot of patches :) Gaël Le 22 juil. 2013 17:09, "Kumar Sukhani" <kumarsukhani at gmail.com> a écrit :

Hello again Gaël, (et al) More on rekindling work on VMKit! Thank you for your interactions thus far on- and off-list. As you suggested in your VMKit-retirement email (to which I'm attempting to respond), I'm interested in producing a Java-to-LLVM compiler out of VMKit. I'd like to take you up on your offer to help understand the architecture. If I can get the a Java-to-LLVM

To compile vmkit on Ubuntu 12.04 64-bit machine, I followed the steps giving here <http://vmkit.llvm.org/get_started.html>[1]. but when I run ./configure I am getting following error- root at komal:/home/komal/Desktop/GSOC/vmkit/vmkit# ./configure >> -with-llvm-config-path=../llvm-3.3.src/configure >> --with-gnu-classpath-glibj=/usr/local/classpath/share/classpath/glibj.zip

Hi Kumar, There is an error on your configuration line, you should provide the path to llvm-config binary instead of configure file. Assuming that you compiled llvm in release mode, the llvm-config binary is located in : YOUR_PATH_TO_LLVM/Release+Asserts/bin/llvm-config Try to change the -with-llvm-config-path option and it will compile.

Hi Nicolas, I found a 32bit Lucid machine (but it'd be great if there was a working 64bit version though). Everything was checked out this morning. I now am able to build vmkit with this configuration: ./configure --with-llvmsrc=/home/zoewolk/RESEARCH/llvm --with-llvmobj=/home/zoewolk/RESEARCH/llvm --with-gnu-classpath-glibj=/home/zoewolk/RESEARCH/classpath-0.97.2/lib

Are you running on 64bit (your backtrace addresses suggest you are)? I'm encountering the same error when trying to use VMKit on 64bit, which I believe is an unsupported target. ~Will On Tue, Aug 23, 2011 at 5:17 PM, Frederic Perez Ordeig <fredericp at gmail.com> wrote: > I'm trying to build the SVN version of VMKit and I'm getting this error > while building. > I

Hi Nicolas, I am so sorry for the questions. According to you, I built VMKit2 on Ubuntu11.10-desktop-amd64 on Intel(R) Corei5, and the previous problem solved. But another one appeared! With the following configuration: elaheh at elaheh-Lenovo-G470:~/Desktop/vmkit2$ ./configure --with-llvmsrc=/home/elaheh/Desktop/llvm/ --with-llvmobj=/home/elaheh/Desktop/llvm/

Oups, sorry for the mistake, llcj (not llc:)) is not more maintained!
