Rubyのtrunkをインストール

Rubyのビルド手順については第1回ログ参照。

今回はsvnの r20629 を使用。

が、いきなりmakeに失敗。

revision.h が無いというエラーがおきるので、

% make up

を実行する。

bison2.4だと parse.c のmakeでこけるらしいので、MacPortsのbison 2.4が入ってたりする人は、

% make YACC=/usr/bin/bison parse.c
% make parse.o

つぎに、parse.yを以下のように変更。

- $$ = in_single;
 + $<val>$ = in_single;

やっぱりRuby開発者の皆さんはMacでビルドなんかしてなくて、Macユーザーはtrunkなんか全然使ってない、ということなんでしょうかね。

ともあれ、なんとかインストール完了。

% ~/ruby/bin/ruby19 -v
ruby 1.9.1 (2008-12-11 revision 20629) [i386-darwin9.5.0]

railsのEdgeを取得

% git clone git://github.com/rails/rails.git rails

% ruby19 ~/src/rails/railties/bin/rails -v
Rails 2.3.0

以下が動作せず。

% ruby19 ~/src/rails/railties/bin/rails

% ruby19 ~/src/rails/railties/bin/rails -h

vつけてもこれだけ。

% ruby19 -v ~/src/rails/railties/bin/rails
ruby 1.9.1 (2008-12-11 revision 20629) [i386-darwin9.5.0]

activesupport/lib/active_support/inflector.rb で死んでることがわかった。

最小ケース by 田中さん

% cat foo.rb
class Foo
end

% cat test.rb
autoload 'Foo', 'foo'
class Foo
end

とりあえずruby-devに報告して、ここで断念。

1_9_1ブランチで実行してみたらどうか？ by ささださん

ビルドに失敗して先に進めず。trunkと同様の変更を入れてみたけどビルドできず(謎)。

じゃあ YARV on Merbでもやるか

% gem19 i merb
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
    bad response Internal Server Error 500 (http://rubyforge.iasi.roedu.net/gems/rake-0.8.3.gem)

rubyforgeが死んでてgemがインストールできず。

Ruby 1.9に期待できること by ささださん

九州Ruby会議01を先取り！

Ruby 1.9.1 preview2 on Rails

% ruby19 ~/src/rails/railties/bin/rails asakusarb4

preview2ならふつうに動く。

server起動

% ruby19 ./script/server
=> Booting WEBrick
=> Rails 2.3.0 application starting on http://0.0.0.0:3000
/Users/matsuda/asakusarb4/vendor/rails/actionpack/lib/action_controller/routing/segments.rb:6: warning: encoding option is ignored - N
=> Call with -d to detach
=> Ctrl-C to shutdown server

警告が出る。 Ruby 1.9では末尾のNが不要。かも。

Rackが落ちる。 @see nariさんの対応

でも Ruby 1.9 のほうは each_lineだね(by ささださん)

ということで、以下のように修正。 ~/ruby/lib/ruby19/gems/1.9.1/gems/rack-0.4.0/lib/rack/handler/webrick.rb

44 if defined? vs.each
 45 vs.each { |v|
 46 res[k] = v
 47 }
 48 else
 49 vs.each_line { |v|
 50 res[k] = v
 51 }
 52 end

これで動いた。

rake test

% rake test

すると死ぬ。以下詳細。

この件に関してはJeremy Kemperからチケット報告済みだったはず。

と思ったら、今日修正がコミットされてるじゃん！akrさん、ありがとうございます！

r20632以降なら動くようになってるのかも？

今回の成果

1. MacでMacPortsのbison 2.4が入ってたりする環境だとmakeに失敗するようになっていたことがわかった

2. autoloadが死ぬ件

3. Rubyのコミットログにasakusa.rbが登場！ by akrさん

4. RackのWEBrickハンドラがRuby 1.9で動かない件
