我正在尝试为 ARM 和 i586 架构构建跨 NG。ct-ng build尝试编译 GCC 时失败。我已经安装了 PPL 1.0-1 版。还尝试了 0.11.2-2 版本。我不明白为什么 GCC 的配置脚本找不到 PPL，而 PPL 已经在那里了......

所有相同的结果：

...

[CFG  ]    checking for the correct version of mpfr.h... yes
[CFG  ]    checking for the correct version of mpc.h... yes

万一这很重要，我的盒子：

uname -m x86_64
distro: archlinux
gcc -v: gcc version 4.7.1 20120721 (prerelease) (GCC)

Crosstool-NG自行下载并构建其依赖项。在 ct-ng menuconfig 中，有这样的注释：

  │ │    ()  Extra addons                                                 │ │  
  │ │          *** WARNING !!!                                            │ │  
  │ │          ***   For glibc >= 2.8, it can happen that the tarballs    │ │  
  │ │          ***   for the addons are not available for download.       │ │  
  │ │          ***   If that happens, bad luck... Try a previous version  │ │  
  │ │          ***   or try again later... :-(

可能下载服务器暂时关闭或您的网络连接中断。“稍后再试” ？

要尝试的另一件事是在 Companion 库下的 ct-ng menuconfig 中选择不同版本的 PPL。就我而言，我选择了 gcc 和 crosstool 不支持的其他版本的组合。尝试使用库存通用 arm-unknown-linux-gnueabi 配置而不进行修改。这对我有用。
