Topic: RubyStack & JRubyStack / RadRails and Rmagick - RMagick.so module not found

Aptana RadRails is very good (eclipse is good), I like it a lot. Particularly with ViPlugin, which (for a cost) gives you a useful subset of the features of the monolitic Vim text editor http://www.satokar.com/viplugin/index.php

I have encountered people who espouse text-editor-only development. I mostly find that this is down to a misguided sense of anti-tool machoism. The slight disadvantage of starting with an IDE is that it may obscure what is actually going on, and encourage dependence on a graphical interface when the underlying command line is actually more elegant. But when you consider the refactoring, debugging, and error flagging abilities of Aptana you see it is so much more productive to use an IDE.

Anyway, I have posted a howto style topic on this (as a separate thread in case others are interested): http://bitnami.org/forums/forums/20/topics/249

Manuel: setting the MAGICK_CODER_MODULE_PATH variable sorted my issues.

Topic: RubyStack & JRubyStack / HowTo: Windows + RubyStack + Aptana RadRails + Ruby Debug

Thought I would make this a new topic. It collates information relating to getting a good development environment running on a windows box (for free):

After following these steps you should have an Aptana RadRails intstalltion, which RubyStack’s Ruby, Rails, ImageMagick and other libraries, and provides visual debugging.

1. Download and Install:
   • RubyStack – http://bitnami.org/stack/rubystack
   • Aptana Studio – http://www.aptana.com/studio/download
2. Configure:
   • Aptana
     • Open Aptana, run Help > Aptana Studio Start Page.
     • Under the central Languages division, find Ruby on Rails, click Install.
       • Check ‘Aptana RadRails’, but UNCHECK the ‘Aptana RadRails Integration’ descendant (this will cause a problem if you do not use MyLyn).
       • Install and Restart
     • Open Window > Preferences > Ruby > Installed Interpreters
       • Click Add RubyVM, enter {RubyStack root directory}\ruby in the RubyVM home directory’ field’
       • Check the RubyVM you just added as the default interpreter
     • Open Window > Preferences > Rails > Configuration
       • Enter the path to the RubyStack Rails, Rake, and Mongrel Rails executables, respectively:
         • {RubyStack root directory}\ruby\bin\rails
         • {RubyStack root directory}\ruby\bin\rake
         • {RubyStack root directory}\ruby\bin\mongrel_rails
     • Open Window > Preferences > Ruby > Debugger
       • Check ‘Use ruby-debug library’
   • Ruby:
     • Run {RubyStack root directory}\use_ruby.bat
       • Enter the command:
         • gem install -y ruby-debug-ide
3. Environment Variables (replace C:\RubyStack with your {RubyStack root directory}):
   • Open Control Panel > System Properties > Advanced
     • Click Environment Variables
       • Edit ‘PATH’ and prepend:
         • C:\RubyStack/sqlite;C:\RubyStack/subversion\bin;C:\RubyStack/imagemagick;
           C:/RubyStack/php;C:\RubyStack/mysql\bin;C:\RubyStack\ruby\bin;
       • Add the variable ‘MAGICK_CODER_MODULE_PATH’, with value:
         • C:\RubyStack/imagemagick\modules\coders

Then you are finished.

Now, when you run Aptana you should be able to add/start ruby servers in debug mode or otherwise. Additionally any features used in your application residing in RubyStack should work.

Note that this breaks the containment of RubyStack, and it would be easy to call the scripts/setenv.bat file from another batch file before opening Aptana to achieve the same effect without altering environment variables.

Topic: RubyStack & JRubyStack / RadRails and Rmagick - RMagick.so module not found

Your cunning suggestion did indeed work, thanks!

Looking at setenv.bat there doesn’t seem to be much other than PATH being prepended, but I notice th MAGICK_CODER_MODULE_PATH variable is also set, I will play with this and report back.

What is the meaning of the forward slashes used for the various paths, such as C:\RubyStack/imagemagick ?

Topic: RubyStack & JRubyStack / RadRails and Rmagick - RMagick.so module not found

I am running RubyStack 1.0 on Windows. I want to run a server through the eclipse-based RadRails (so I can use the ruby-debug-ide, to get visual debugging).

My project uses RMagick. I have configured RadRails/Aptana to use RubyStack’s Ruby VM, and RubyStack’s Rails.

When I start a server and fetch an action that works from within the UseRuby environment I get the following error:

“The specified module could not be found. – C:/RubyStack/ruby/lib/ruby/gems/1.8/gems/rmagick-1.15.9-win32/ext/RMagick.so”

The module does exist, and is in that folder. I think this is a PATH issue, but I have tried the following with no avail:

- Adding C:/RubyStack/ruby/lib/ruby/gems/1.8/gems/rmagick-1.15.9-win32/ext/ to my windows PATH environment variable.
- Adding C:\RubyStack/imagemagick (which appears in the use_ruby.bat PATH) to my windows PATH.

Any suggestions much appreciated
