3 The GNAT Compilation Model

This chapter describes the compilation model used by GNAT. Although similar to that used by other languages such as C and C++, this model is substantially different from the traditional Ada compilation models, which are based on a centralized program library. The chapter covers the following material:

• Topics related to source file makeup and naming
  • Source Representation
  • Foreign Language Representation
  • File Naming Topics and Utilities
• Configuration Pragmas
• Generating Object Files
• Source Dependencies
• The Ada Library Information Files
• Binding an Ada Program
• GNAT and Libraries
• Conditional Compilation
• Mixed Language Programming
• GNAT and Other Compilation Models
• Using GNAT Files with External Tools
