I have localhost:3000 working.  
Windows xp system  
I placed sqlite3.exe and dll in windows/system directory and made sure  
it was in the path.

When I used gem install sqlite3-ruby it gave a large number of  
errors indicating no definition. Looked like it couldn’t find the  
master table or something.

Other than placing sqlite3.exe in the windows\system was I supposed to  
create a db table? Not clear from two different books I bought.

I got the say/hello application working. Wondering what to do next or  
should I continue to follow the tutuorial?

There were many error lines. The last one follows the pattern of all  
of them.

After invoking gem install sqlite3-ruby I got

‘No definition for \_wrap\_sqlite3\_aggregate\_context’

The say hello program works however.

Using gem install sqlite-ruby it seemed to install without these  
messages but the webrick server would crash as soon as I tried to do  
the say/hello example.

Do I just rename sqlite3.exe to sqlite.exe and try again?

Post the actual error message you get from the gem install. That  
makes it much easier to give you some help.

Sqlite3 is what you want to use. Before installing sqlite3-ruby you  
need to be sure you’ve got sqlite3 installed correctly. The site to  
go to is: [http://www.sqlite.org/](http://www.sqlite.org/).

You can follow the Downloads link to get the pre-compiled version for  
Windows. You want to get both sqlite-3\_6\_20.zip and  
sqlitedll-3\_6\_20.zip. They need to be installed in a directory that  
is on your path.

I have little experience with the MS environment but  
sqlite3\_aggregate\_context comes from the sqlite3 api. I’m guessing  
that, if you’ve already installed sqlite3, that it cannot be found  
when you do “gem install sqlite3-ruby” Part of the gem installation  
includes compiling some c code. This code will need sqlite3 header  
files and library.
