Question

我想在Mac OS X（Mavericks）上安装libRmath.dylib，最好使用Homebrew，因为我已经使用了这个包管理器。

我没有找到libRmath的公式，但我确实找到了R的公式，所以我尝试将其扩展（最后查看整个文件）：

# Also build libRmath.dylib
system "cd src/nmath/standalone"
system "make"
system "make install"
system "cd ../../.."
lib.mkpath
ln_s prefix+"R.framework/Resources/lib/", lib

如果我手动执行命令，./configure; cd src/nmath/standalone; make会创建libRmath.dylib。但不使用brew install r。我在libRmath.dylib中找不到Cellar。我究竟做错了什么？（请注意，我是Ruby和Homebrew公式的新手。）

以下是整个文件。

Answer 1

Formula r现在有选项with-librmath-only，它只构建独立的libRmath库。

使用Homebrew在Mac OS X上安装libRmath
