MissingSourceFile: no such file to load -- sqlite3/database

Hi,

I'm using active_record and sqlite3-ruby (gem) modules. When I try to
connect to sqlite3 database, I get a error :

"MissingSourceFile: no such file to load -- sqlite3/database"

I have "sqlite3/database.rb" in my $: path as shown below.

Does anyone know what this means or what causes it ?

My environment is :

- ruby 1.8.7 (2008-08-08 patchlevel 71) [i686-linux]
- gem 1.2.0

[gems]
- activerecord (2.1.0)
- activesupport (2.1.0)
- sqlite3-ruby (1.2.2)

Thanks in advance for any help.

Below are shown the steps of how this error occurs and some information
about database and RUBYLIB.

Try the advice given here:

http://wuhai.wordpress.com/2008/07/0...lite3database/

It would be REALLY nice if the maintainers would release 1.2.3 with a fix.

Are you sure you've read access on the file?

"Sorry, no posts matched your criteria."

> It would be REALLY nice if the maintainers would release 1.2.3 with a fix.

True. Or anything, really -- this is damned sloppy.

I'm seriously considering Amalgalite (spelling?), just because it seems
actively maintained.

Short answer: The permissions on that file are wrong. They're wrong in the
gem. You'll have to fix them manually.

Seems to be fixed -- or at least, not broken. Thanks!

Hey, it worked right before I posted it. :-)

Glad to hear 1.2.3 has been released.

About the changes on "ruby.h", they already there under ruby 1.8.7.

But, shame on me, I have not realized the missing 'r' permission for
'others':

--- snip ---
-rw-rw--w- 1 root root 24774 2008-08-26 18:54 database.rb
--- snip ---

Changing this permission as suggested in the link, have solved the
problem

Thanks for the help/time, Jos !

I haven't had:

--- snip ---
-rw-rw--w- 1 root root 24774 2008-08-26 18:54 database.rb
--- snip ---

I've corrected that

Welcome. But 1.2.3 doesn't run out of the box either, at least on CentOS 5 with
the stock Ruby 1.8.5.

/usr/bin/ruby: symbol lookup error:
/usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.3/lib/sqlite3_api.so:
undefined symbol: RSTRING_PTR

$ nm sqlite3_api.so | grep RSTRING
U RSTRING_LEN
U RSTRING_PTR

http://github.com/jamis/sqlite3-ruby...690e5987744cd2
says it fixes linking against Ruby 1.8.5 but the sqlite3_api_wrap.c generated
by swig (from extconf.rb) defines the necessary RSTRING_* macros too late in
the generated code. Moving the defines up in the generated file works around
the problem, but I'm not sure what the right fix is as the defines already sit
at the top of the sqlite3_api.i file.
