Unable to configure JRuby for IDE debugging based on the lack of mkmf support
-----------------------------------------------------------------------------
Key: JRUBY-2611
URL: http://jira.codehaus.org/browse/JRUBY-2611
Project: JRuby
Issue Type: Bug
Components: Extensions
Affects Versions: JRuby 1.1.1
Environment: Ubuntu 8.04, JRuby 1.1.1+ (from svn), NetBeans 6.1-Full
with JRuby support
Reporter: Eric M. Smith
Fix For: JRuby 1.1.1
In order to debug JRuby applications under NetBeans 6.1 and other IDE's, the
IDE requires the use of ruby-debug-ide. This has a dependency on
ruby-debug-base which requires a native code module to be compiled.
Due to the lack of support for native code, attempts to install this Gem result
in:
Building native extensions. This could take a while...
extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)
from extconf.rb:1
ERROR: Error installing ruby-debug-base:
ERROR: Failed to build gem native extension.
As a result of this, systems written under JRuby 1.1.1+ cannot be debugged
using NetBeans 6.1 or other IDE's that require ruby-debug-ide to be installed
as a gem.
While it is understandable that the JRuby team does not want to support native
code to enable easy application distribution, since there exists two distinct
categories of gems that require native code (development specific gems like
ruby-debug-base and production gems like mysql) there needs to be a way to use
gems which require native code for development specific actions like debugging
or a replacement/substitute should be provided such as one of either :
1) making an exception to allow gems necessary for standard development
practice like debugging.
or
2) gems which provide native platform integration like ruby-debug-base and
ruby-debug-ide need to be provided as part of the JRuby platform.
