eventmachine

[Chhi'mèd Künzang]

I tried getting the eventmachine gem working on MagLev (1.0.0-27184) with no luck.  I tried the main branch and also the fork in the maglev section at GitHub.

It's also entirely possible that I did something wrong along the way.  Has anyone else successfully installed eventmachine?

Either way, can anyone offer any advice for either getting this working or determining how hard that would be?

Thanks,

Chhi'mèd

Chhi'mèd,  can you post the error(s) here that you're seeing when you attempt to install eventmachine?  Next, are you using this with a Rails or Ruby application with Bundler?

 

Thanks,

Chhi'mèd

Think different and code well,

Hi

It seems something changed in MagLev itself that made the EM C-ext not
load. I fixed that in the Maglev/eventmachine repository, and it loads
now, and runs some tests. Not all tests work, though, and I would
recommend the pure Ruby version of EM, unless you need features that
only the C-ext has.

Chhi'mèd, I would also recommend filing an issue here with the steps to reproduce:

Here's what I got after fetching the latest from the MagLev version.  It looks like maybe a development pathname is built into the bundle?

Hm

This is a pathname for the Mac OS X build, I'm not sure what's going on,
but I got rid of my Mac some time ago, so I'm just guessing.

One thing that seems strange to me is that rubyeventmachine.bundle
should have a direct reference to that libssl, since it should have
compiled and linked on your machine. Secondly, I'm not sure how rvm sets
this up, but running from the source tree, I have the rubyeventmachine
shared object in lib/maglev/gems/1.8/gems/eventmachine-1.0.0.beta.4/ext/

Have you tried running from a source tree, or else install and run
MagLev using rbenv[1] and ruby-build[2]? RVM juggles with the paths for
Ruby installs, so it may be something wrong there.

If the problem persists, please file an issue on github with the backtrace.

This is a known issue. I'm not sure why that version got pushed out, but I'll try and get a correct version out shortly.

We can look into this for the next MagLev update, which we're planning in August. There is a dependency on finishing up a customer release of GS/S 3.1.0.1 which will be used as the underlying VM, so plans could get delayed.

Okay, thanks for all the help.  I'll keep an eye on the next release and see what happens.
