Yesterday, I decided I was going to get Cloud9 running on my BeagleBoard. I didn't document every step, but below are a few helpful hints. I'm working with a recent Angstrom Distribution build with Node.JS v0.2.6.
At first, I tried using Node.JS v0.2.1 and I found that the 'connect' module wasn't present. I went to install 'npm', but the install attempts failed silently. When I found that v0.2.6 was in the feeds, I tried installing 'npm' again and it succeeded without much of a headache. I installed v0.2.19 of 'npm'.
Since the node-o3-xml package needs to be compiled for Cloud9, I installed a bunch of native tools onto my BeagleBoard, including 'opkg install task-sdk-native nodejs-dev', but I don't remember 100% of what I installed. My confusion began around an error on 'import Scripting' when running node-waf. Fortunately, someone already figured the issue out for me when they were trying to build node-inotify on a Gumstix board. I installed the extra Python tools and copied the .py code from my Mac. I did need to edit wscript to remove any x86 specific optimization flags and remove any .pyo files that accidentally got copied over.
Once I built o3, I installed it into my Cloud9 directory, which I checked out following the online directions. I am working from the Cloud9 0.2.0 tag. Since the submodules of Cloud9 include a set of pre-built binaries for o3, I added a repository that included my newly built ARM binaries.
I think this was pretty much it to getting Cloud9 invoked, but using the latest Firefox 4 beta as a client wasn't working. I tried using the '-d' flag at invocation and moving Cloud9 to a user account instead of root, but that didn't help. Based on a blog post that described invoking Cloud9 on an Ubuntu machine, I was using this command-line to perform the start-up:
node ~/cloud9/bin/cloud9.js -c ~/cloud9/config.js -w ~/testproject -d
I decided to install Chrome to see if it was a browser dependency and viola!
After a simple web server app, I decided to poke the LED SYSFS entries. I needed to change the SYSFS file entry permissions to 777 to enable my user account to set the state, but I was easily able to do so.
Am I the only one that gets how cool it will be to be able to distribute pre-configured SD cards you can drop into your BeagleBoard, plop it onto a network and start editing code to peek and poke hardware using an IDE without ever installing *anything*?
