我正试图使用crosstool-ng构建一个工具链，我已经设置好了所有这些，并按照上所述选择了我的cpuhttp://crosstool-ng.org/#download_and_usage我正处于可以构建我的工具链的阶段。然而，当我输入ct-ng build时，它会取消，并出现以下错误：

我知道它无法检索内核，有没有办法手动下载它并告诉脚本tarball的位置？
好吧，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将通过代理下载tarball。所以我把/usr/bin/wget复制到/usr/binwget~origand wrote a wrapper/usr/bin/wget`，看起来像：
#!/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中得到了以下内容：
[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'

它是如何自动知道我原来的wget二进制文件现在被称为wget~orig的？？？Andit尝试使用它来代替我现在位于/usr/bin/wget的包装器(是的，我已经添加了x权限并尝试过了，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)现在运行得很好。。。
您可以配置ct-ng以阻止其下载源：
ct-ng menuconfig
- 转到
Path and misc options - 在
*** Downloading ***中，选择[*] Forbid downloads - 退出
当您尝试构建工具链(ct-ng build)时，构建过程将期望您将手动下载的tarball放入~/src中。
只要检查build.log就知道需要什么防水球。
好的，
由于wget是用muliple(9)参数调用的，所以我将包装器脚本(在/usr/bin/wget)修复为：
#!/bin/bash
/usr/bin/wget~orig --no-check-certificate $1 $2 $3 $4 $5 $6 $7 $8 $9
这似乎成功地下载了ct-ng所需的源tarball
您可以将ct-ng配置为向wget传递额外的参数：ct ng菜单配置
- 转到
Path and misc options - 在
*** Downloading ***中，在Connection timeout选项下 - 选择
(--passive-ftp --tries=3 -nc --progress=dot:binary... - 添加
--no-check-certificate - 退出
这是不安全的，但它允许您放弃为其他答案中提到的wget创建包装脚本
