Cygwin1.7にMeCab0.98+MeCab-rubyをインストールしたメモ
インストール: MeCab 0.98
$ ./configure --with-charset=utf-8 CPPFLAGS=-DNOMINMAX LIBS=-liconv --prefix=/usr/local $ make $ make install
prefixつけた以外は参照ページと同じ。
CPPFLAGSオプションつけない時はmakeでこける(なんか文法エラーで……)。こけ方は以下。

MeCab-ruby
$ ruby extconfig.rb $ make $ make install
の手順だと、makeでこける。

mecabライブラリをうまく探してくれないのでリンク時にこけてる模様。やりかたがわからなかったのでruby extconf.rbで生成されるMakefileを直接編集して直した。
# before ldflags = -L. # ... LIBS = $(LIBRUBYARG_SHARED) -lstdc++ -ldl -lcrypt # after ldflags = -L. -L/usr/local/lib # ... LIBS = $(LIBRUBYARG_SHARED) -lstdc++ -ldl -lcrypt -lmecab
これでビルド可能
