在Mac上安装R gsl软件包 [英] installing R gsl package on Mac

问题描述

我正在尝试为R安装gsl软件包，据我理解，这只是OSX Mavericks下GSL的包装.我已经尝试了显而易见的方法:

I'm trying to install the gsl package for R, which I understand is simply a wrapper around the GSL, under OSX Mavericks. I've tried the obvious:

> install.packages('gsl')
Installing package into ‘/Users/myusername/Library/R/3.1/library’
(as ‘lib’ is unspecified)

   package ‘gsl’ is available as a source package but not as a binary

Warning in install.packages :
  package ‘gsl’ is not available (for R version 3.1.0)

所以我跑了

> install.packages('gsl',type = 'source')
Installing package into ‘/Users/myusername/Library/R/3.1/library’
(as ‘lib’ is unspecified)
trying URL 'http://cran.rstudio.com/src/contrib/gsl_1.9-10.tar.gz'

opened URL
==================================================

* installing *source* package ‘gsl’ ...
** package ‘gsl’ successfully unpacked and MD5 sums checked
checking for gsl-config... no
configure: error: gsl-config not found, is GSL installed?
ERROR: configuration failed for package ‘gsl’
* removing ‘/Users/myusername/Library/R/3.1/library/gsl’
Warning in install.packages :
  installation of package ‘gsl’ had non-zero exit status

未安装GSL.天哪！所以我通过Homebrew安装GSL:

No GSL install. D'oh! So I install GSL via Homebrew:

~  brew install gsl
==> Downloading http://ftpmirror.gnu.org/gsl/gsl-1.15.tar.gz
######################################################################## 100.0%
==> ./configure --prefix=/usr/local/Cellar/gsl/1.15
==> make
==> make install
  /usr/local/Cellar/gsl/1.15: 239 files, 6.7M, built in 101 seconds

尝试再次安装R软件包:

Try to install the R package again:

> install.packages('gsl',type = 'source')

(as ‘lib’ is unspecified)

我显然会以错误的方式进行操作，但是不确定问题出在哪里.

I'm obviously going about this the wrong way but am unsure about where exactly the problem lies.

推荐答案

通过标准的brew安装，我可以使工作正常(OS X Yosemite 10.10，R 3.1.1，gsl 1.16，gsl R包1.9-10).通过分别用gsl-config --cflags和gsl-config --libs的输出手动在CFLAGS和LDFLAGS前面加上前缀，R和gsl.

I was able to get things working (OS X Yosemite 10.10, R 3.1.1, gsl 1.16, gsl R package 1.9-10) with standard brew-installed R and gsl by manually prefixing CFLAGS and LDFLAGS with the output from gsl-config --cflags and gsl-config --libs respectively.

以下:

CFLAGS="-I/usr/local/opt/gsl/include" LDFLAGS="-L/usr/local/opt/gsl/lib -lgsl -lgslcblas" R
...
> install.packages("gsl")

为我工作.

请注意，gsl-config列出了通往我的酒窖的直接路径，上面的路径是Brew符号链接.

Note that gsl-config lists the direct path to my Cellar, the paths above are brew symlinks.
