Linux下的命令源码下载

1、首先安装dpkg-dev：

apt-get install dpkg-dev

2、设置资源的URL

进入 sudo vim /etc/apt/sources.list ，然后加入以下URL：

deb-src http://archive.ubuntu.com/ubuntu trusty main restricted #Added by software-properties deb-src http://gb.archive.ubuntu.com/ubuntu/ trusty restricted main universe multiverse #Added by software-properties deb-src http://gb.archive.ubuntu.com/ubuntu/ trusty-updates restricted main universe multiverse #Added by software-properties deb-src http://gb.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse #Added by software-properties deb-src http://security.ubuntu.com/ubuntu trusty-security restricted main universe multiverse #Added by software-properties deb-src http://gb.archive.ubuntu.com/ubuntu/ trusty-proposed restricted main universe multiverse #Added by software-properties

并执行命令：apt-get update

不然会报错： apt-get (You must put some ‘source’ URIs in your sources.list) E: You must put some ‘source’ URIs in your sources.list

3、下载相应的源码，这里以ls为例

注意：最好在root下，运行下面命令

（一）查找ls命令的位置 ， 执行：which ls

运行结果：/bin/ls

（二） 查找命令所在的包，执行：dpkg -S /bin/ls

运行结果：coreutils: /bin/ls

（三） 下载源码，执行：apt-get source coreutils

（四）下载完成后，当前目录下面可以看到四个文件，其中coreutils-8.21是源码的目录，相应的源码在它里面 。

可能出现的错误：

W: Download is performed unsandboxed as root as file coreutils_8.21.orig.tar.gz couldnt be accessed by user _apt. - pkgAcquire::Run (13: Permission denied) root@morun:/home/# ls

情况一：当前目录已经生成了三个文件，还差一个源码目录

这时可以通过手动解压源码包，产生源码目录

执行：dpkg-source -x coreutils_8.21-1ubuntu5.4.dsc （你的xxx.dsc）

可能出现的错误

W: Download is performed unsandboxed as root as file coreutils_8.21.orig.tar.gz couldnt be accessed by user _apt. - pkgAcquire::Run (13: Permission denied) root@morun:/home/hukejian# ls

情况二：当前目录没有生成任何文件

方法：

一、执行：sudo chown _apt /var/lib/update-notifier/package-data-downloads/partial/

二、然后再执行一遍：apt-get source coreutils
