linux - Enabling gcc-multilib manually after successful gcc installation on Debian system? -

i installed gcc-4.7.2 on i686 debian system don't know how enable gcc-multilib after installation.

i installed gcc-4.7.2 on debian system configuration "--enable-multilib" not work.

i copied files(gcc-multilib package files) @ same location mentioned in gcc-multilib package file list though not work.

i guess must install gcc-multilib:

sudo apt-get install gcc-multilib libc6-dev-i386
