怎样打开64位 Ubuntu 的32位支持功能

大多数使用基于 Ubuntu/Debian 的发行版的人都更倾向于选择64位的系统对吧这是因为64位的系统能够充分发挥你的硬件的全部性能 它使你能够在更紧张的内存资源下使用更复杂的软件而且是真的快速使用不必每次做一件小事都要等上许久。现在32位仅有一个优点那就是没有太多兼容性上的问题。每次JAVA更新都很让人很困惑因为大多数用户都不能获得需要的库文件。在过去很多别的软件和驱动也没有64位版。

因此如果现在你有一个64位架构的系统而且你可以使用之前的支持包括驱动、64位版本和任何一个你需要的软件。这样就避免了所有的问题对吧现在有一个让你可以在64位系统中使用32位软件的方法爽吗就在你读了这篇文章然后照着做了之后就可以了。如果你有一个13.10或更高版本的Ubuntu/Debian你需要安装一个叫做 ia32-libs 的基础包。现在,这个包已经被废弃了,所以你必须手工安装。

下面的命令可以在 Ubuntu/Debian 13.10 或更高的发行版上运行。

###第一步: 确认你有一个64位架构的内核

你可以打开终端然后输入:

dpkg --print-architecture

你将会看到像下面这样的内容:

amd64

这说明着你已经拥有了64位架构内核。

###第二步: 确认你打开了多架构支持功能

(多架构支持可以让你在有64位库的情况下使用32位库。)

输入:

dpkg --print-foreign-architectures

输出是:

i386

如果你还没有多架构支持你需要打开它。

另一种第二步: 打开多架构支持。

输入:

sudo dpkg --add-architecture i386

sudo apt -get update

然后就会开始下载更新然后运行。

之后你需要输入:

sudo apt-get dist-upgrade

它会检查你已经拥有的库文件是否有更新的版本。

若果然有的话,它会问你是否需要更新(y/n)。

如此这般你就已经成功地为你的64位系统安装了32位支持了。
