and Gemfile:

platforms :mri do
    gem "memcached", ">= 0.20.1"

Full details:

Long story short, the memcached gem cannot be installed on the travis box.

I would really like to get Padrino running on travis. Can you update the vagrant memcached recipe so that the 'memcached' gem can be installed successfully.


This turns out to be a known memcached gem issue:


I am trying to work around it but the root of the issue seems to in the configure script bundled with memcached [gem].


It seems like there is no way to work around the issue with a bundled configuration script. Please use dalli which both installs fine and is actually maintained. Or push memcached gem authors to fix this issue on 32-bit ubuntu 10.04 and do a new gem release.


Fair enough, thanks for looking into this


I personally think that if you can make your code use either dalli or memcached (as a fallback), that will be beneficial to Padrino users, too. And as soon as you are doing that, we will be happy to host you on Travis. dalli installs just fine in our environment.


Yeah we actually support a pluggable architecture for cache stores so Dalli also is tested and supported as well and is used as the default. The memcached support was more of about giving people options. I simply removed memcached from our Gemfile for now and still include Dalli.

Worked great:!/padrino/padrino-framework/builds/68622. The JRuby problem seems to be unrelated:

$ bundle install
connect: Connection refused
Done. Build script exited with: 1

but all the others pass. Weirdly enough this used to be that jruby was the only one that passed just a few builds ago...odd the connection is refused now.


JRuby problems are known, we are waiting for JRuby core team members to come home from all the conferences to help us with investigations. And also release 1.6.4.

JRuby also has 2 more issues:

  • C extensions support crashes 32-bit JVM
  • Officially documented way of disabling C extensions is broken

So we recommend people to disable testing against JRuby until these issues are resolved. And ask JRuby team to release 1.6.4 soon and pay attention to those issues.

We also provide 1.9.3 (preview1, of course) and rbx-2.0 (Rubinius 2.0.0pre), you may want to test against those.


Excellent thanks for the heads up, I wasn't aware of the issues with JRuby. I will disable JRuby and add rbx-2.0 support for now. Hopefully we can enable jruby again soon. Thanks for the quick response.

@michaelklishin michaelklishin referenced this issue from a commit in travis-ci/travis-cookbooks
@michaelklishin michaelklishin Install libsasl2-dev as part of the memcached recipe
It was originally a part of travis-ci/travis-ci#204 investigation. Even though libsasl
actually has nothing to do with that particular issue, it is a useful addition to

Enabled ruby-head and rbx-2.0 and things are looking good, disabled jruby for now. I assume even with libsasl2-dev installed my problem would still persist with memcached?


the problem is in configure script[s] memcached gem bundles. I installed libsasl2-dev just because it is a recommended addition (for memcached but not just).


I see ok makes sense. As I said everything seems fine for us now. Glad to have Padrino on travis-ci finally and thanks for your guys hard work on this. Awesome project!


Try this. It worked for me

apt-get install gettext


Wow landtax, you saved my day!
