glibc ubuntu install

Question

Estoy usando Ubuntu 14.04.2 LTS /n /l .

Aquí están las libc que instalé.

$ 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

Pero cuando hago $ sudo apt-get install libdbus-1-3:i386

Me pregunto ¿cuál es la diferencia entre libc6: i386 y libc6-i386?

Answer 1

libc6: i386 es la versión i386 de libc para núcleos / sistemas de arquitectura i386. Esto es para ejecutar paquetes creados para sistemas i386 y sería necesario si está tratando de usar paquetes i386 en un sistema amd64. Esto se llama multiarch.

libc6-i386 es el paquete de desarrollo de 32 bits de libc para sistemas amd64. Esto no es para ejecutar software, es para compilar y vincular código de 32 bits.
