Ruby Enterprise and WebROaR

[Bruno Guimarães Sousa]

Hi everyone!

Installed ruby enterprise edition 1.8.7-2010.02 and now i'm trying to install webroar.
Don't know where to find the dynamic ruby library (libruby.so) for it. Read http://groups.google.com/group/webroar/browse_thread/thread/30502a739701534a?pli=1 and none of those solutions worked.
Here is the error:
# webroar install
Checking for the dependencies ...
Checking for ruby........found   at /usr/local/ree/bin/ruby.
Checking for libruby.so.1.8.7........not found.
Unable to find libruby.so.1.8.7 at /usr/lib.

The following dependencies required for installation could not be found:
libruby.so.1.8.7
Please refer the user guide for the list of prerequisites.
Sorry, WebROaR could not be installed on this machine.

# find / -name libruby.so*
(returned no results)

Searched for it in REE sources and nothing there.

How can I solve it? I couldn't compile REE with --enabled-shared flag?

Bruno,

Please refer:
http://www.rubyenterpriseedition.com/documentation.html#_rubycocoa_compatibility_and_tt_enable_shared_tt

In our testing, we have installed REE by passing '--enable-shared'
argument to 'installer' script and it has worked for us.

./ruby-enterprise-X.X.X/installer -c --enable-shared

Please let us know, how it goes with you?

Thanks,
Dharmarth

Thanks!
It did work! I had to remove previous instalation, extract source files, recompile it and then it was fine.
I'm just worried about what is said in http://www.rubyenterpriseedition.com/documentation.html#_rubycocoa_compatibility_and_tt_enable_shared_tt :
"Please note that enabling --enable-shared will make the Ruby interpreter about 20% slower. It is for this reason that we don’t recommend enabling --enable-shared on server environments, although it’s fine for desktop environments."

Is that true?

It would be true(as their creator saying it). We haven't benchmarked
it with WebROaR, once we starts supporting static Ruby build(very much
on our top TODO), we would surely do our benchmarks and let you know.

Please do share your experience with WebROaR.

Thanks,

Dharmarth,
I don't understand much about the difference between using shared libraries and static Ruby build. Why does WebROaR needs to use those  shared libraries from ruby interpreter ? Are they recompiled somehow?

I'm writing a paper about Rails applications benchmarks. In this paper is been compared different application servers, and how RoR apps would scale with load balancers softwares. As soon as it's done, i'll translate it to english and publish.

Bruno,
There was some mistake in embedding Ruby interpreter, which was
causing load path error with static Ruby build. That forced us to use
shared Ruby build. We have committed necessary fixes, and WebROaR
should work with static/dynamic Ruby build. You can checkout latest
code from github and test in your setup.

Please do share your benchmarks methodology and results. We would be
happy to have look on it.

Thanks,
Dharmarth

Bruno,
We have recently released WebROaR v0.4.0, which supports static Ruby
build. Please check out the release announcement for details:
