【问题描述】：
我正在尝试使用crosstool-ng 构建工具链，我已经全部设置好，按照http://crosstool-ng.org/#download_and_usage 中的说明选择了我的 cpu，我正处于可以构建工具链的阶段。但是，当我输入 ct-ng build 时，它会取消并出现以下错误：
$ ct-ng build

我知道它无法检索内核，有没有办法可以手动下载它并告诉脚本 tarball 的位置？
好的，我意识到了
wget http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz 将失败，但 wget --no-check-certificate http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz 将可以通过代理正常下载 tarball。
所以我将/usr/bin/wget 复制到 /usr/binwget~origand wrote a wrapper/usr/bin/wget` 中，如下所示：
#!/bin/bash
/usr/bin/wget~orig --no-check-certificate $1
但这似乎也不起作用，我现在在build.log 中得到以下信息：
[DEBUG] ==> Executing: 'wget' '--passive-ftp' '--tries=3' '-nc' '--progress=dot:binary' '-T' '10' '-O' '/home/ron/src/toolchain/work/.build/tarballs/linux-4.3.tar.xz.tmp-dl' 'http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.xz'
[ALL ] wget~orig: missing URL
[ALL ] Usage: wget~orig [OPTION]... [URL]...
[ALL ]
[ALL ] Try `wget~orig --help' for more options.
[DEBUG] Not at this location: "http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.xz"

[ALL ] wget~orig: missing URL

它是如何自动知道我原来的wget 二进制文件现在称为wget~orig？ Andit 尝试使用它而不是我现在位于 /usr/bin/wget 的包装器（是的，我已经添加了 x 权限并尝试了它，来自 shell 的 wget http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz （使用我的包装器脚本）现在工作得很好...... .
