Well, that didn’t seem to go too well. It seems that somewhere in the
mkmf / extconf.rb soup the actual location of the mysql home has
gotten lost. The only way this will work is if mysql is installed in /
usr/local, the default for the distributed precompiled version is to
go in /usr/local/mysql.

I haven’t figured out how to pass “–with-mysql-dir” or any of the
other extconf.rb variants in on the command line so here’s what I did.
- Download the source from tmtm.org
- Modify extconf.rb such that for line 15:
WAS: inc, lib = dir_config(‘mysql’, ‘/usr/local’)
IS: inc, lib = dir_config(‘mysql’, ‘/usr/local/mysql’)
- Create a mysql.gemspec thus:
#################
require ‘rubygems’
require ‘rake’
version = Dir.pwd.split(pattern=“-”).last
spec = Gem::Specification.new do |s|
s.name = “mysql”
s.version = “#{version}”
s.email = “[email protected]”
s.homepage = “MySQL/Ruby”
s.platform = Gem::Platform::RUBY
s.summary = “MySQL/Ruby provides the same functions for Ruby
programs that the MySQL C API provides for C programs.”
s.files = FileList[‘[A-Za-z]*’].to_a
s.extensions = [“./extconf.rb”]
end
if $0 == FILE
Gem::Builder.new(spec).build
end
