kldd: ldd Style Analysis For Solaris Kernel Modules

in Oracle Solaris Performance, Panics, Hangs, and Dtrace (MOSC)

Solaris 11.4 comes with a new user level command, /usr/bin/kldd.

kldd performs ldd style analysis for kernel modules.

The ldd utility is used to analyze the dependencies of a userland dynamic object. Given an object, it tells you what other objects it depends on, as well as revealing related details.

This is very basic, and very useful ability. ldd has been part of our product since it debuted, along with support for dynamic linking in SunOS 4.0 in late 1988.

It subsequently became part of AT&T System V Release 4 Unix, and has been adopted by numerous other Unix vendors, and Linux. The reason for this ubiquity is that ldd performs a basic and necessary service.

Howdy, Stranger!
