Failed to write core dump. Core dumps have been di

Question

I am beginner in shoes app, when I was trying to run a shoes app in the Ubuntu 12.04 terminal using shoes samples/test22.rb I'm getting this error:

Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again.

So how can I solve this or some one help me to run a simple shoes app in ubuntu and make a desktop app?

Answer 1

I'm guessing you are running shoes4. It runs fine for me on ubuntu 14.04, so let's figure out the difference.

First, posting samples/test22.rb would be nice as test22.rb does not exist in the shoes repo and even sample22.rb does not exist (anymore).

E.g. important factors that could lead to this crash are the shoes version, the JRuby version and the JDK version.

Here are my values:

tobi@tobi-desktop ~/github/shoes4 $ bin/shoes -v
Shoes 4.0.0.pre4
tobi@tobi-desktop ~/github/shoes4 $ jruby -v
jruby 1.7.20 (1.9.3p551) 2015-05-04 3086e6a on OpenJDK 64-Bit Server VM 1.7.0_79-b14 +jit [linux-amd64]
tobi@tobi-desktop ~/github/shoes4 $ java -version
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)
tobi@tobi-desktop ~/github/shoes4 $ uname -a
Linux tobi-desktop 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

For 12.04 my personal guess would be an outdated JVM version on which SWT does not run anymore.
