HP-UX Linker and Libraries User's Guide

2 Determining How to Link Programs or Libraries (Linker

Tasks)

You have a great deal of control over how the linker links your program or library by using ld

command-line options. This chapter describes the tasks you can perform to determine how programs

and libraries must link by using the Compiler commands and Linker commands.
