Re: GSoC project nio4r

[Tony Arcieri]

Hi there!

I'm really glad to hear you're interested in working on nio4r! I'd also be glad to be your mentor.

There are a number of potential projects you could work on. I listed filesystem monitoring as one, but there are other outstanding ones including the ability to change "interest ops" on the fly.

ruby-core contributor Koichi Sasada also mentioned it would be interesting if Ruby could reach feature parity with Python asyncio, so if you could build out the interesting features from Python asyncio into nio4r that'd be great.

Hi Tony,
I have a small question. Is there any template structure you would prefer for the GSoC Application. 

Thanks and Regards,
Upekshe.

[Tony Arcieri]

That's a really good question! Let me do some research to see if there's any recommendations for it.

I believe Melange has a standard template.

Hello Tony,

I find Python Software Foundation has a detailed template for proposal. Maybe we can refer to it.

Here is this template: http://www.google-melange.com/gsoc/org2/google/gsoc2015/python

This is a nice template...I agree, we should adopt this format or something very close.

First I clone the git repo. Then I install the Development Kit, and follow the instructions in the wiki page of https://github.com/oneclick/rubyinstaller/wiki/Development-Kit#quick-start . Then 
Then run the commands 
'gem install bundler'

'bundle'

'rake compile'

none of them give me errors. But when I run the command 'rake' it gave me the above error. Then I re-install the ffi (gem install ffi --platform=ruby), But still the same error.

Am I doing something wrong. I am currently using Windows 8. BTW, the files mentioned in the error are in place. According to the error it is a Load error.
I am really grateful if you can provide me some help with this problem.

Hi Upekshe,

I don't know a whole lot about Ruby on Windows but I pinged someone who might be able to help.

Hi Tony,
Thanks for that. Anyway I decided to move to Ubuntu, Which I though would be the best option. I think It will be easy for both you and me since it is better to stay on the same platform, when discussing problems arise when developing. :) .

Thanks and Regards,
Upekshe

[Tony Arcieri]

Cool, sounds good!

It seems the source of this particular problem may have been the FFI gem has not been updated to support Ruby 2.2 on Windows yet.

Better Windows support for nio4r would be an interesting project in and of itself! But Ubuntu makes it easier for me as a mentor ;)

Hi Tony,

I installed Ubuntu and It seems I was able to build the project nio4r successfully. :D
Thanks for the help provided, (Y).
