libc6 6:i 386和libc6 6-i 386有什么区别？

Question

我在用Ubuntu 14.04.2 LTS \n \l。

下面是我安装的libc。

$ dpkg --list | grep libc6
ii  libc6:amd64                                           2.19-0ubuntu6.7                                     amd64        Embedded GNU C Library: Shared libraries
ii  libc6-dbg:amd64                                       2.19-0ubuntu6.7                                     amd64        Embedded GNU C Library: detached debugging symbols
ii  libc6-dev:amd64                                       2.19-0ubuntu6.7                                     amd64        Embedded GNU C Library: Development Libraries and Header Files
ii  libc6-i386                                            2.19-0ubuntu6.7                                     amd64        Embedded GNU C Library: 32-bit shared libraries for AMD64
rc  libc6-x32                                             2.19-0ubuntu6.7                                     amd64        Embedded GNU C Library: X32 ABI Shared libraries for AMD64

但当我做$ sudo apt-get install libdbus-1-3:i386时

出现下列错误

我想知道libc6 6:i 386和libc6 6-i 386之间有什么区别？

Answer 1

libc 6:i 386是libc的i386版本，用于i386体系结构内核/系统。这是为了运行为i386系统构建的包，如果您试图在amd64系统上使用i386包，则需要这样做。这就是所谓的多重弓。

Libc6-i 386是用于amd64系统的32位libc开发包。这不是用于运行软件，而是用于编译和链接32位代码。
