I installed Rails 1.8.6 on a Panther system. Everything is ok but I  
can’t install sqlite3-ruby gem. This is the terminal result:

* * *

$ sudo gem install --local sqlite3-ruby-1.2.1.gem  
Building native extensions. This could take a while…  
ERROR: Error installing sqlite3-ruby-1.2.1.gem:  
ERROR: Failed to build gem native extension.

/usr/local/bin/ruby extconf.rb install --local sqlite3-ruby-1.2.1.gem

checking for sqlite3\_open() in -lsqlite3… no

make  
make: \*\*\* No rule to make target `ruby.h', needed by`sqlite3\_api\_wrap.o’. Stop.

Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/  
sqlite3-ruby-1.2.1 for inspection.  
Results logged to /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.1/  
ext/sqlite3\_api/gem\_make.out

I try to solve the problem today looking for something similar in  
newsgroups but I did’t find anything useful. Any suggestions?

I solved the problem using this command line:  
sudo gem install sqlite3-ruby – --with-sqlite3-include=/opt/local/  
include --with-sqlite3-lib=/opt/local/lib  
the problem was that the sqlite3 was not installed in the default  
locations.

Thanks again,  
G.

I see the problem with install gem sqlite3-ruby. This way help me to fix  
it! Just install developer headers for provide compile the library from  
sources.  
SQLite3:

Without the -d option, rails will default to sqlite. To install SQLite3:

~$ sudo apt-get install libsqlite3-0 libsqlite3-dev  
~$ sudo gem install sqlite3-ruby
