Rails - May 2006 - Rails, Ubuntu dapper & Mongrel > uninitialized constant Mongrel::HttpHandler error

This on Ubuntu testing with the default ruby1.8 package, RubyForge current
gems, mongrel...this look familiar to anyone??

andre@andre:~/rails_apps/depot$ mongrel_rails
/usr/lib/ruby/gems/1.8/gems/mongrel-0.3.13/lib/mongrel/rails.rb:44:
uninitialized constant Mongrel::HttpHandler (NameError)

Looks very familiar, had the same issue this afternoon on a system
that didn''t have a compiler tool chain installed.  The error is
because you haven''t compiled the HttpHandler module and thus mongrel
can''t run.  Check you have gcc installed and check the installation
process to see that it compiles http11 okay.

Paul.

gcc and friends installed, but http11 didn''t compile properly...kernel
header sources needed for this ?? it just seems kinda strange for a gem to
require this stuff...

I''ll probably take this over to "mongrel-users", not sure
it''s still
appropriate for "rails"...but maybe good for the listmonger to index
for
future people with same issue...

I actually use Ubuntu now *just* so I can suffer through all the crap
people have to put up with from the Debian packaging of Ruby.  That''s
right, I suffer so everyone might get some relief.

First off, the pre-release (0.3.13) now checks to see if http11.so
actually built and spits out a nasty error message.  This should help
with the silent denial from RubyGems when things fail.

Second, I have to write up the official Mongrel documentation on this
but here''s what got me started:

  * http://howtoforge.com/perfect_setup_ubuntu_5.10_p5

That whole series is really good, but this will get you a decent base
apache, php, mysql setup going.  It''s a little dated but should help a
lot.

Then there''s this older documentation set, with these specific
packages:

  * http://www.howtoforge.com/ruby_on_rails_apache2_fastcgi_debian_p4

These instructions install a whole ton of stuff, so you might want to go
through them too.  And remember that the stuff is old, so you''ll want
to
confirm versions and such.

Then you''ll also want to install packages for readline, irb, ri, and
potentially ruby1.8-dev if that didn''t get installed.  (I had to
install
it, but other folks don''t).  If you get really stuck and desperate then
you can try the shotgun approach:

  sudo apt-get install `apt-cache search ruby | cut -d '' '' -f
1`

But I really don''t suggest this.  When all that''s done, then
you should
go grab the source to RubyGems, install that manually (don''t use
debian''s since they install to weird locations IIRC).

Additionally, most people don''t even bother with Debian''s
packages and
instead compile Ruby from source.  I actually do this, but on my Ubuntu
machine I forced myself through the pain so I can write up some
instructions.  YMMV.

Once you''ve done all that, I recommend that you complain to the package
maintainers to create a meta-package that allows you to build gems that
have compiled extensions in them.

The irony of the whole problem is if you bring up performance as a
complaint people go off about how you need to learn C and make
extensions and you''re a whiner.  If you complain about how difficult it
is to setup Debian with a Ruby capable of building extensions the Debian
folks go off about how you''re an idiot and somehow carving a package
into 200 discrete pieces makes it easier to test (because we all know
that additional complexity makes things easier).

Since this is such a dichotomy with Ruby--and Mongrel is all about
making it easier for folks--I''ll hopefully have some documentation for
Mongrel users on this to match the Win32 documentation, but of course
it''ll be much much longer since even with Ubuntu it''s a royal
pain to
get a decent development system going.

Let me know how far you get.

Thanks Z for the info, I''ll fight with it until I finish it or it

me, then I''ll post back.

If you choose to install Ruby from source, but still want it Debian
packaged (for easy removal or updating in the future, and all of those
other great things that apt/dpkg provides), you can use checkinstall to
create a package.  It''s pretty easy to use.

Just sudo apt-get install checkinstall, then, instead of doing ''make
install'' as the last step of installing via the make chain, just type
''checkinstall'' instead.

So:
./configure
make
checkinstall

FWIW, I used Ezra Zygmuntowicz'' instructions [1] for setting up a
deployment server, using Ubuntu instead of Debian, and things are
going just fine. I upgraded to Dapper before it was released, so I
could get ruby 1.8.4 instead of Breezy''s 1.8.3.

Perhaps there''s something in Ezra''s directions that will be
helpful.

I''m currently running Litespeed, proxying to Mongrel. I had some
issues with Mongrel_Cluster which were probably related to Ubuntu''s
ruby packaging, but I figured out a solution and have written it up at
[2].

Very nice Alison.  Glad you got over the nasty debian hump.  It still
baffles me why that platform is so difficult for Ruby.

  ** Also check if you have ''make'' installed **.

I had a similar problem - installed ubuntu 6.06 x86_64 yesterday and mongrel
rails complained about uninitialized constant. I had gcc already installed,
but was  surprised to discover that ubuntu does not install GNU make by
default! Ubuntu is indeed an user-  not nerd-oriented system ;-)!

After the installation of ''make'' with synaptic, I had to
uninstall mongrel
# sudo gem uninstall mongrel
and install it again:
# sudo gem install mongrel.

Now mongrel_rails starts as it should.
