无法获取linux tarball

Question

我正在尝试使用crosstool-ng构建一个工具链，我已经全部设置好了，选择了usage上描述的cpu，现在我可以构建我的工具链了。但是，当我输入ct-ng build时，它将取消以下错误：

$ ct-ng build

在build.log中，我得到以下内容：

我知道它无法检索内核，有什么方法可以手动下载它并告诉脚本tarball位于哪里？

好的，我意识到wget http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz会失败，但是wget --no-check-certificate http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz会通过代理很好地下载tarball。因此，我将/usr/binwget~origand wrote a wrapper/usr/bin/wget`复制/usr/bin/wget，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'
[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
[ALL  ]    Usage: wget~orig [OPTION]... [URL]...

它如何自动知道我最初的wget二进制文件现在被称为wget~orig？和试图使用这个，而不是我现在位于/usr/bin/wget的包装(是的，我已经添加了x权限并尝试了它，从外壳(利用我的包装脚本)的wget http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz现在工作得很好.

Answer 1

好吧,

由于wget是用多个(9)参数调用的，所以我将包装器脚本(at /usr/bin/wget)固定如下：

#!/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。

Answer 2

您可以配置ct-ng以防止它下载源代码：

ct-ng menuconfig

• 转到Path and misc options
• 在*** Downloading ***中，选择[*] Forbid downloads
• 出口..。

当您尝试构建您的工具链(ct-ng build)时，构建过程将期望您将手动下载的tarball放在~/src中。

只要检查一下build.log，就知道需要什么焦油球了。

Answer 3

您可以配置ct-ng将额外的参数传递给wget：ct-ng menuconfig。

• 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
• 出口

这是不安全的，但是它允许您放弃为wget创建其他答案中提到的包装脚本。
