Developing applications with IBM Open XL C/C++

By default, when you invoke the IBM® Open XL C/C++ compiler, all of the following phases of translation are performed. Usually, compiling and linking are combined into a single step

• Preprocessing of program source
• Compiling and assembling into object files
• Linking into an executable

You can use compiler options to perform only certain phases, such as preprocessing, or assembling. You can then re-invoke the compiler to resume processing of the intermediate output to a final executable.

The following sections describe how to invoke the IBM Open XL C/C++ compiler to preprocess, compile, and link source files and libraries:
