sqlite-ruby gem not building extension

Jim Freeze

Hi all

I am having troubles building the sqlite-ruby gem.
I don't think it is a gem problem, but a extconfig issue.

% gem install sqlite-ruby -v 2.2.3
Attempting local installation of 'sqlite-ruby'
Local gem file not found: sqlite-ruby*.gem
Attempting remote installation of 'sqlite-ruby'
Select which gem to install for your platform (powerpc-darwin7.7.0)
1. sqlite-ruby 2.2.3 (mswin32)
2. sqlite-ruby 2.2.3 (ruby)
3. Cancel installation

Building native extensions. This could take a while...
ERROR: While executing gem ... (RuntimeError)
ERROR: Failed to build gem native extension.
Gem files will remain installed in
/Users/jdf/local_ruby/ruby-1.8.2/lib/ruby/gems/1.8/gems/sqlite-ruby-2.2.3 for
inspection.
ruby extconf.rb install sqlite-ruby -v 2.2.3\nchecking for main() in
-lsqlite... no
checking for sqlite.h... no


Results logged to
/Users/jdf/local_ruby/ruby-1.8.2/lib/ruby/gems/1.8/gems/sqlite-ruby-2.2.3/ext/gem_make.out

For some reason, it is not finding my sqlite library and include file.
I have them, and I have even set environment variables to locate them:

% env | grep -i flag
CFLAGS=-I/Users/jdf/local/include
LDFLAGS=-L/Users/jdf/local/lib

% ls /Users/jdf/local/include/
sqlite.h
% ls /Users/jdf/local/lib
libsqlite.0.8.6.dylib libsqlite.a libsqlite.la
libsqlite.0.dylib libsqlite.dylib pkgconfig

The following should work, but does not:

% cd /Users/jdf/local_ruby/ruby-1.8.2/lib/ruby/gems/1.8/gems/sqlite-ruby-2.2.3/ext
% ruby extconf.rb
checking for main() in -lsqlite... no
checking for sqlite.h... no

Are there some tricks to get extconf to find my lib and include files?

Wow, thanks.

% ruby extconf.rb --with-sqlite-dir=/Users/jdf/local
checking for main() in -lsqlite... yes
checking for sqlite.h... yes
checking for sqlite_open() in -lsqlite... yes
creating Makefile

How do I get rubygems to do this? Chad, Jim, anyone??

gem install sqlite-ruby -v 2.2.3 -- --with-sqlite-dir=/Users/jdf/local

Uses the double dash separate similar to the old startx script with X.

....
On a parallel note, be aware that many people having tried to use
SQLite3 with RoR have at some point given up.
After a good start, I had an issue with the usage of quotes around
columns name. Sometimes they were OK, sometimes they seemed missing.
I met that issue when I started using a Table.find_by_column call but
couldn't make it work. The same code worked like a treat with MySQL,
which unfortunately was over-dimensioned for my little hack (where
SQLite would have been perfect).
Before using such constructs, the adapter behaved as expected. So your
mileage may vary ...
