无法通过自制安装GCC48 - 卷曲的错误（AUTH？）

Question

我需要C11支持，但我似乎无法从自制安装gcc48：

$ brew install gcc48 
==> Downloading ftp://gcc.gnu.org/pub/gcc/snapshots/4.8.0-RC-20130316/gcc-4.8.0-RC-20130316.tar.bz2 

curl: (9) Server denied you to change to the given directory 
Error: Download failed: ftp://gcc.gnu.org/pub/gcc/snapshots/4.8.0-RC-20130316/gcc-4.8.0-RC-20130316.tar.bz2 

Answer 1

似乎curl不给予适当的错误，从而误导你认为这是某种授权问题。

真正的问题是指定的目录在ftp服务器上不存在。也许这是一个自制问题。

$ wget ftp://gcc.gnu.org/pub/gcc/snapshots/4.8.0-RC-20130316/gcc-4.8.0-RC-20130316.tar.bz2
