homebrewでRをインスコ

homebrewにscienceをtap

$ brew tap homebrew/science

gfortranはgccに含まれているのでこのまますんなりインスコと思いきや。

$ R

どうも、gfortranのライブラリを読み込んでいない。

$ ls /usr/local/lib/gcc/
4.9

ん！　x86_64-apple-darwin14.0.0なんてdirectory無いぞ！
libgfortran.3.dylib　は/usr/local/lib/gcc/4.9/の下にあるみたい。
x86_64-apple-darwin14.0.0/4.9.2/ directryにsymbolic linkしても良いが、libR.dylibを書き換えたほうがよさげ。

$ otool -L /usr/local/Cellar/r/3.1.2/R.framework/Versions/3.1/Resources/lib/libR.dylib

ヤッパね。

$ install_name_tool -change /usr/local/lib/gcc/x86_64-apple-darwin14.0.0/4.9.2/libgfortran.3.dylib /usr/local/lib/gcc/4.9/libgfortran.dylib /usr/local/Cellar/r/3.1.2/R.framework/Versions/3.1/Resources/lib/libR.dylib

確認。

マジか？　で、

$ install_name_tool -change /usr/local/lib/gcc/x86_64-apple-darwin14.0.0/4.9.2/libgfortran.3.dylib /usr/local/lib/gcc/4.9/libgfortran.dylib /usr/local/Cellar/r/3.1.2/R.framework/Versions/3.1/Resources/library/stats/libs/stats.so

としておけー！
