sqlite3-ruby gem install problem

Tom Cloyd

8/4/2008 1:18:00 PM

[on Kubuntu Linux 8.04.1, with Ruby 1.8.6 and latest rubygems]

I think the installation routine was looking for sqlite3.h and couldn't
find it, but I may be way off. I'm clearly beyond my comfort/knowledge
boundary...again. Here's the first part of the console output:

===
tomc@tomc-desktop:~/Ruby-work$ sudo gem install sqlite3-ruby
[sudo] password for tomc:
Building native extensions. This could take a while...
ERROR: Error installing sqlite3-ruby:
ERROR: Failed to build gem native extension.

/usr/local/bin/ruby extconf.rb install sqlite3-ruby
checking for fdatasync() in -lrt... yes
checking for sqlite3.h... no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

Well, drat. While poking around a blog post about the Junebug wiki,
relevant because it's installed on the Radiantcms.org website (which
presumably is running Radiant (!) - and that confuses me - I found this:

"make sure you have the libsqlite3-dev package installed on
(ubuntu|debian), or the sqlite gem won't compile"

I love secret knowledge, but only when I'm in on the secret. I simply
cannot imagine how I might have know this in advance.

In any case, THAT IS in the adept package manager, and installing solved
the problem.

On to the next one.

You probably need the libsqlite3-dev package.

Niklas, I would only ask you to consider that there are people out there
struggling with ruby - to get some rather mundane things done (like
translate HTML to Textile) - who come from very far away, conceptually.
We find minutes in the evening, and sometimes hours on weekends, to do
our struggling. We do NOT know what header files are (could that be
because we're not C programmers? Maybe. I'm just guessing, though.) Many
things are a mystery to us.

I'd love to take a year off and get really educated in things
Ruby-related, but that's not going to happen. I'm glad - very glad -
that there are forums to which we can bring our simple questions, else
we'd mostly just die in the midst of our perennial ignorance.

So, I'm glad that what's a problem for me probably isn't for most other
people here on in the Ruby community. And I do know that every month a
learn a little more, but it comes slowly.

I'm not in any way offended by anything you said, or by the fact that my
question might have seemed bafflingly simple. I'm just wanting to
explain things a bit. I'm an expert in a very different field, and I
know that THERE, it also is easy to forget how little others know who
pass through my world only occasionally. For what it's worth, in well
over a decade of being professionally involved in my field, and
avocationally involved in yours, I never once met any who comes close to
my level of knowledge of matters relating to computer and programming.
I'm sad about that, but it's true. Here I'm pretty dumb, true, but not
in the rest of the world. (All of which is not much help to me when I
get stuck.)

But don't worry. I'll likely give you and others occasion to practice
patience again, and possibly soon!

t.
