gem install rmagickするとchecking for stdint.hでコケる

rmagick死ねカス。

さて、centos5に、ImageMagickが公式バイナリとしてrpmで出している6.6.9を（ImageMagick-develも一緒に）突っ込んである環境下で、rmagickのためにgemでインストールしてみます。ちなみにRuby1.9.2の環境。

[root@samidare ~]# gem install rmagick
Building native extensions.  This could take a while...

まじ、カス。ぐぐると、ruby-list MLにこのような記事が見つかり、同じようにしてみると

# vi /usr/local/lib/ruby/gems/1.9.1/gems/rmagick-2.13.1/ext/RMagick/extconf.rb

  $LOCAL_LIBS = ENV["LIBS"].to_s     + " " + `Magick-config --libs`.chomp

This installation of RMagick 2.13.1 is configured for
Ruby 1.9.2 (x86_64-linux) and ImageMagick 6.6.9 Q16
======================================================================

このようにMakefileが生成できた。出来たんだけどmake installじゃないんだろうしmake通っても、どないせいっちゅうねん。

まじrubbishだわ。.bash_profileなどにPATH通したりもしたけどうーんこ。まじうんこ。RMagick非推奨で今後はいこう。個人的には一生ご縁が無いだろうし。

追記；Makefileあった…。 /usr/local/lib/ruby/gems/1.9.1/gems/rmagick-2.13.1/Makefile 、なのでmake && make installしてみたが、、わからん。irbからrequire ‘RMagick’するとerror。もういいや。
