MeCabる手順.md

classpathは$HOME/opt/lib/mecab-javaにする。

$ sudo emerge app-text/mecab

$ cd $HOME/tmp

$ wget https://mecab.googlecode.com/files/mecab-java-0.996.tar.gz

$ tar xvf mecab-java-0.996.tar.gz

$ mv mecab-java-0.996 $HOME/opt/lib/mecab-java

$ cd $HOME/opt/lib/mecab-java

$ patch < $HOME/tmp/Makefile.patch ### oracle-jdkに変更＆UTF8化

$ make

$ $HOME/tmp

$ LD_LIBRARY_PATH=$HOME/opt/lib/mecab-java/:$LD_LIBRARY_PATH scala -cp $HOME/opt/lib/mecab-java/MeCab.jar:. mecab-scala.scala
