我正在尝试为ARM和i586架构构建交叉NG。ct-ng build在尝试编译GCC时失败。我已经安装了PPL版本1.0-1。还尝试了0.11.2-2版本。我能理解为什么GCC的配置脚本找不到PPL，而它已经存在了。。。
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
[CFG ] checking for the correct version of the gmp/mpfr/mpc libraries... yes

如果这很重要，我的盒子：
uname -m x86_64
distro: archlinux
gcc -v: gcc version 4.7.1 20120721 (prerelease) (GCC)
Crosstool NG下载&建立自己的依赖关系。在ct-ng菜单配置中，有这样一条注释：
│ │ () 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... :-(
也许下载服务器暂时关闭，或者你的网络连接出现故障。"稍后再试"？
另一件需要尝试的事情是在Companion库下的ct ng menuconfig中选择不同版本的PPL。在我的案例中，我选择了一个gcc和其他版本的组合，而交叉工具不支持这些版本。尝试在不修改的情况下使用股票通用arm未知linux gnueabi配置。这是为我构建的。
