Homebrew で R をインストールする時に cairo.h がないエラーになるので cairo を外して回避する

Last updated at Posted at 2014-01-08

brew install r が以下のようにエラーとなる。

$ brew tap homebrew/science
Cloning into '/usr/local/Library/Taps/homebrew-science'...
(略)
$ brew doctor
Your system is ready to brew.
$ brew install r
==> Using Homebrew-provided fortran compiler.
This may be changed by setting the FC environment variable.
==> Downloading http://cran.r-project.org/src/base/R-3/R-3.0.2.tar.gz
(略)
/private/tmp/r-pW8z/R-3.0.2/lib/libRlapack.dylib is unchanged

Using Homebrew-provided fortran compiler. とあるので gfortran は入れる必要ないようだ。

エラーログをファイルにとる。

$ HOMEBREW_MAKE_JOBS=1 brew install -v r 2>&1 > _brew.log
Error: r did not build
$

_brew.log を見ると

(略)
In file included from devX11.c:72:
./devX11.h:62:12: fatal error: 'cairo.h' file not found
#  include <cairo.h>
           ^
1 error generated.
make[3]: *** [devX11.d] Error 1
make[2]: *** [make.X11] Error 2
make[1]: *** [R] Error 1
make: *** [R] Error 1

(略)

cairo.h が見つからなくてエラーになっている。

$ brew upgrade cairo
Error: cairo-1.12.16 already installed

cairo は最新。

R depends on cairo? を参考に、brew edit r して configure のオプションで cairo を外す。

$ brew edit r

エディタが立ち上がるので、以下のような部分を探して、

  def install
    args = [
      "--prefix=#{prefix}",
      "--with-aqua",
      "--enable-R-framework",
    ]

ここに --without-cairo を付け加える。

  def install
    args = [
      "--prefix=#{prefix}",
      "--with-aqua",
      "--enable-R-framework",
      "--without-cairo",
    ]

すると brew install r で R がインストールされる。このように cairo を外すと、きっとグラフィックス機能の一部が使えなくなるだろうと思う。
