I would like to build the executable of CompassApp, a GUI application that lets webdesigners compile stylesheets by using SASS and Compass without using the command line.

The source can be found on GitHub here: https://github.com/handlino/CompassApp.

CompassApp is a an application developed in Jruby.

From the GitHub webpage of the project:

If you want to build your own copy, you will need JRuby and rawr

I am using Windows 7 as operating system for my webdesign projects. I never built a jruby app from source. It seems on linux it's easier to install the required things, anyway i'm using Windows now.

First i cloned the GitHub repository.

Then i installed jruby.

Now i should install rawr (https://github.com/rawr/rawr)

It seems that rawr also requires javac and rake

I saw that rawr and rake are 2 ruby gems.

  1. So how do i install those 2 ruby gems for jruby on Windows?
  2. And how do i build CompassApp from source after i have everything i need?

I would need a step by step guide from the install of the requirements to the build of the application.

(i never used jruby in the past).

If someone of you develops apps in jruby i think that can help me easily.

I thank you in advance.

@Fabio Hi, we made Compass.app and Fire.app :-)

It is easy to build Compass.app on OS X or Linux. We have a (almost) step by step guide about building Fire.app on the GitHub wiki and it can be applied to Compass.app too: https://github.com/handlino/FireApp/wiki

We have never tried to build it on Windows, and do not think it can be done easily.

Thanks for your answer. I didn't try yet but as you said it seems (almost) a step by step guide. A similar wiki could be added also to Compass.app on github, so others may find it more easily. I'll try to install it, anyway i also bought your app after some time trying building it from source :P

I'm trying to do a similar thing, but in my case only package the gems in a self-contained executable jar. the docs are not very descriptive and some are outdated.

I tried rawr but managed to get further with warbler

here's what I did: I created a folder named jrcompass and installed compass into it:

c:\test\jrcompass>%JRUBY%\jruby -S gem install compass -i .

I installed warbler and then ran the warble command in that folder:

C:\test\jrcompass>c:\apps\jruby\bin\jruby -S warble

that created a ~20MB jar file named jrcompass.jar which is farther than I got with rawr.

now I'm trying to execute the jar with:

C:\test\jrcompass>java -jar jrcompass.jar

and I get the following error below. I hope that this will help you make progress. please let me know if you figure it out.
