Chapter 2. Compiling and linking
Developers porting code to the AIX operating system from other UNIX operating systems might, at first, have difficulties with the compile and linking tasks on AIX. This chapter helps the developers with the tasks on AIX by providing the following sections:
Section 2.1, “32- and 64-bit development environments” on page 38
Section 2.2, “Compiling and linking: A quick overview” on page 43
Section 2.3, “Resolving symbols at link-time” on page 53
Section 2.4, “Supported link methods on AIX” on page 63
Section 2.5, “Run-time linking” on page 68
Section 2.6, “Dynamic loading” on page 82
Section 2.7, “Commands when manipulating objects and libraries” on page 85
Section 2.8, “Creating shared objects” on page 92
Section 2.9, “Shared libraries in a development environment” on page 99
For further information about the compile and linking tasks on AIX and how to manage shared libraries, please refer to AIX 5L Version 5.2 General Programming Concepts: Writing and Debugging Programs and the ld command section in AIX 5L Version 5.2 Reference Documentation: Commands Reference.
Note
The definitions shown in Table B-1 on page 443 are very useful in understanding the technical details of linking and loading process on AIX.
