Question

我正在尝试使用crosstool-ng构建工具链，我已将其全部设置完毕，按照http://crosstool-ng.org/#download_and_usage中的说明选择了我的cpu并且我在我可以构建我的工具链的步骤。但是当我输入ct-ng build时，会取消以下错误：

$ ct-ng build

在build.log我得到以下内容：

我知道它无法检索内核，有没有办法可以手动下载并告诉脚本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会失败，但wget --no-check-certificate http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.gz可以通过代理下载tarball。所以我将/usr/bin/wget复制到/ usr / binwget~oru and wrote a wrapper / 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"
[DEBUG]    Trying 'http://www.kernel.org/pub/linux/kernel/v4.x/longterm/v4.3/linux-4.3.tar.xz'

[ALL  ]    wget~orig: missing URL
[ALL  ]    Usage: wget~orig [OPTION]... [URL]...

如何自动知道我的原始wget二进制文件现在被称为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（利用我的包装脚本）现在工作得很好......

Answer 1

您可以配置ct-ng以防止其下载来源：

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，构建过程会要求您将手动下载的tarball放在~/src中。

只需检查build.log即可知道需要哪些tar包。

Answer 2

好，

由于使用muliple（9）参数调用wget，我修改了我的包装器脚本（在/usr/bin/wget）看起来像：

#!/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

所需的源代码压缩包

Answer 3

您可以配置 ct-ng 以将额外参数传递给 wget： 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，但是它允许您放弃为其他答案中提到的 wget 创建包装器脚本

crosstool-ng无法获取linux tarball
