This article contains instructions on how to create a true multilib Slackware64. A multilib 64bit Linux system is capable of running 64bit as well as 32bit software. The Filesystem Hierarchy Standard dictates the best way to achieve a clean separation between 64bit and 32bit software on a single system. With Slackware64 we chose to adopt this standard, so it has been prepared to look for 64bit libraries in /lib64 and /usr/lib64 directories. This is why I call Slackware64 “multilib-ready” - even though 32bit libraries will be looked for in /lib and /usr/lib, Slackware64 does not ship with any 32bit software.
