Homebrew R建立缺少开罗 [英] Homebrew R build missing Cairo

问题描述

我使用brew在OSX 10.7.5服务器上安装了R:

I installed R on an OSX 10.7.5 server using brew:

brew install R

一切似乎都还可以，但是开罗无法正常工作:

Everything seems so OK far, however Cairo is not working:

> svg(tempfile())
Warning messages:
1: In svg(tempfile()) :
  unable to load shared object '/usr/local/Cellar/r/2.15.2/R.framework/Resources/library/grDevices/libs//cairo.so':
  dlopen(/usr/local/Cellar/r/2.15.2/R.framework/Resources/library/grDevices/libs//cairo.so, 6): image not found
2: In svg(tempfile()) : failed to load cairo DLL

共享对象文件似乎完全丢失:

The shared object file seems to be missing completely:

id-86-243:Resources jeroen$ ls -ltr library/grDevices/libs/
total 488
-rwxrwxr-x  1 jeroen  admin  245764 Dec 22 17:03 grDevices.so

我很少使用OSX，所以我不太确定这是否是R的特定发行版中的错误，还是在构建它时做错了什么?

I rarely use OSX, so I am not quite sure if this is a bug in this particular distribution of R, or if I have done something wrong when building it?

推荐答案

我只是遇到了这个问题.在R configure阶段，pkg-config定位cairo似乎是一个问题.解决方法似乎是:

I just ran into this problem. It seems to be a problem with pkg-config locating cairo during the R configure stage. The workaround seems to be:

export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig

以便R可以正确使用cairo.

我直接从源代码而不是通过homebrew来安装R，但是我确实使用homebrew来使其他库保持最新.这样可以为我解决问题.

I install R directly from source, rather than with homebrew, but I do use homebrew to keep other libraries up to date. This resolves the problem for me.

作为参考，我正在运行OSX Mavericks.

For reference, I am running OSX Mavericks.
