Runtime Libraries

A runtime library provides low-level functions that support high-level C and C++ language features, such as memory management and file system access. Conceptually, a runtime library acts as an interface between a target system's hardware or operating system and the CodeWarrior C or C++ runtime environment.

This CodeWarrior product includes many runtime libraries and support code files. These files are here:

    installDir \PowerPC_EABI_Support\Runtime 
  

where installDir is a placeholder for the path in which you installed your product.

For your projects to build and run, you must include the correct runtime library and startup code. These sections explain how to pick the correct files:

• Required Libraries and Source Code Files
  Every CodeWarrior project must include a runtime library.
• Allocating Additional Heap Space
  If you specify a heap size in the EPPC Target settings panel, the linker creates a default heap of this size. The default heap needs no initialization.
• Choosing a Runtime Library
  Substrings embedded in the name of a runtime library indicate the type of support the library provides. Use these substrings to pick the runtime library appropriate for your project.
