Using a prebuilt library● is one of n or f for normal and full, respectively● is either empty for no support for position-independent code or p forposition-independent code.Note: The library configuration file has the same base name as the library.The IAR Embedded Workbench IDE will include the correct library object file andlibrary configuration file based on the options you select. See the MSP430 IAREmbedded Workbench® IDE User Guide for additional information.If you build your application from the command line, you must specify the followingitems to get the required runtime library:●●●Specify which library object file to use on the XLINK command line, for instance:dl430fn.r43Specify the include paths for the compiler and assembler:-I msp430\incSpecify the library configuration file for the compiler:--dlib_config C:\...\dl430fn.hNote: All modules in the library have a name that starts with the character ? (questionmark).You can find the library object files and the library configuration files in the subdirectory430\lib.CUSTOMIZING A PREBUILT LIBRARY WITHOUT REBUILDINGThe prebuilt libraries delivered with the MSP430 IAR C/C++ Compiler can be used asis. However, it is possible to customize parts of a library without rebuilding it. There aretwo different methods:● Setting options for:● Formatters used by printf and scanf● The sizes of the heap and the stack● Overriding library modules with your own customized versions.The following items can be customized:Items that can be customizedDescribed inFormatters for printf and scanf Choosing formatters for printf and scanf, page 51Startup and termination code System startup and termination, page 56Low-level input and output Standard streams for input and output, page 60Table 12: Customizable items50MSP430 IAR C/C++ CompilerReference Guide
