ubuntu - libc6 :i386 and libc6-i386有什么区别

Question

我正在使用 Ubuntu 14.04.2 LTS\n\l。

这是我安装的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

但是当我执行 $ sudo apt-get install libdbus-1-3:i386

出现以下错误

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

我想知道 libc6:i386 和 libc6-i386 之间有什么区别？

Answer 1

libc6:i386 是 i386 架构内核/系统的 libc 的 i386 版本。这是为了运行为 i386 系统构建的包，如果您尝试在 amd64 系统上使用 i386 包，则需要这样做。这称为多架构。

libc6-i386是libc为amd64系统开发的32位开发包。这不是用于运行软件，而是用于编译和链接 32 位代码。
