Unable to install memcached gem on ree-1.8.7-2011.03 on OS X 10.7

[eric]

I've been unable to compile the "memcached" gem with REE built with ruby-build.

@evan suggested I submit an issue about it here.

Here is the log of the compile:

https://gist.github.com/4ddb0712bf09f80858a4

I initially submitted it as ruby-build issue 99 but @jeremy pointed out the issue is either with rbenv or the memcached gem.

From @jeremy:

Looks like this may be because the memcached gem is reinvoking ruby to build libmemcached: https://github.com/evan/memcached/blob/master/ext/extconf.rb#L58

Does anyone have any suggestions for the best way to fix this?

[jeremy]

Did RBENV_VERSION=ree-1.8.7-2011.03 gem install memcached work?

[eric]

It did not. It has the same issue.

[jeremy]

To troubleshoot, I'd git clone the memcached repos, build the gem, and install it. If it failed, I'd go into its ext dir and ruby extconf.rb and make directly. Then work through why.

I did both and they work for me on a variety of Ruby versions, with and without rbenv.

From those logs, it looks like a linking issue in memcached, which could imply that there's another older libmemcached lib confusing things (missing symbols, struct members missing, .. ?)

(What led to suspecting this is a rbenv or ruby-build issue?)

[eric]

@evan suggested filing a ticket with you guys because it works fine on both the standard OS X ruby and on other REE installs, which made it seem likely it was something specific about the way ruby was compiled or some other environmental thing.

[jeremy]

OK -- good luck troubleshooting! Please update with your progress :)

Is this still a problem? This is related to #121

However I can compile memcached gem just fine. So closing
