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。
