Solaris 1.x to 2.x Transition Guide

Reorganized Libraries

Several functions and groups of functions were moved into different libraries. This can cause references to these functions to be flagged as undefined when compiling a SunOS release 4.x application in the Solaris 2.6 environment.

After a compile, check the man page of any functions flagged as undefined. The synopsis list both the -l linker option and any include files that you need to resolve the symbol.
