= Mac OS X Mountain LionでRのrglパッケージをインストールする(Rでglを使う)

[2012-08-31 13:37:14]

Mac Portsで入れたRでplot3d使おうとしてrglパッケージをインストールしたらエラーがでた．

こんなエラー

GLが見つかってないようですね．

portsでのRのインストールオプションでopenglを指定できるかと思ったけど，どうもわからんかったので，openglのパスを通すことにしました．

Xcodeのインストールが必要だと思います．

glの場所を探す

% locate GL/gl.h
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/include/GL/gl.h
% locate libglut
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib/libglut.3.7.dylib
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib/libglut.3.dylib
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib/libglut.dylib
/usr/X11/lib/libglut.3.dylib

パスを指定しながらパッケージをインストール

Installing rgl in R under OS X Lion | drop.bit ここをみてたらMacPortsでfreeglutをインストールすればいいみたいですが，Xcodeに入ってるのでそっちを指定することにしました．

install.packages("rgl", configure.args="--disable-cocoa --with-gl-includes=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/include --with-gl-libs=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/lib --with-x")

これでうまくいった．
configureオプションの --disable-cocoa と --with-xが必要なのかは確認してません．
