I'm seeing this with Jato's master:

penberg@titan:~/jruby$ jato -jar lib/jruby.jar -e "puts 'hello'"
hello

Are you using the 0.3 release? If so, can you please try with latest master? If master is broken, please include hello.rb here and I'll see if I can reproduce.

[SDkie]

yes.

root@sdkie:/home/sdkie/# jato -version
java version "1.6.0"
Jato VM version 0.3

should I get latest master from:
git clone git://git.kernel.org/pub/scm/java/jato/jato.git
or
git clone https://github.com/jatovm/jato.git

Actually I tried from both, both giving me same issue.

[penberg]

@SDkie Development happens on Github, I'm just mirroring on git.kernel.org.

Can you please share hello.rb so that I can also try to reproduce?

[SDkie]

@penberg

root@sdkie:/home/sdkie/Desktop/programs# cat hello.rb
puts "Hello World"

[penberg]

@SDkie OK, I'm still not able to reproduce. What GCC version are you using?

[SDkie]

@penberg
root@sdkie:/home/sdkie# gcc -v

[penberg]

@SDkie Oh, this is on x86-64? I've been trying to reproduce on 32-bit. The 64-bit architecture is still known to be broken. See #36, for example, which I'm debugging right now. Once I that's fixed, I'll see if I can get JRuby working also.

[SDkie]

@penberg 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 currently jato support ARM architecture?

[penberg]

@SDkie No, not really. There's some ARM specific code in the tree but it's not very useful.

[SDkie]

@penberg I can help you reproduce this error when you will be working on this issue.

[penberg]

@SDkie I finally managed to track down and fix #36. If you have time, can you please retest JRuby and report back if it works or not?

[SDkie]

@penberg : Great 👍 I will test it in within next 2 days.

[penberg]

@SDkie, thanks!

[SDkie]

@penberg : tested it on
OS: Linux komal 3.5.0-26-generic #42~precise1-Ubuntu SMP Mon Mar 11 22:17:58 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Latest JRuby version: jruby 9000.dev (2.1.0.dev) 2013-11-13 f84e398 on jato 1.6.0 [linux-x86-64]

but no success :(

[penberg]

@SDkie Thanks for testing - I'll look into it!

[penberg]

@SDkie Btw, does make check pass on your machine?

[SDkie]

Here are the last few lines of make check:

Annotation processing got disabled, since it requires a 1.6 compliant JVM
REGRESSION
100% [88/88] corrupt.CorruptedMaxLocalVar
88 tests passed, 1 tests skipped (26.34 s)

[penberg]

@SDkie Interesting - all the tests pass. I'll look into what's wrong with JRuby!
