C251 User's Guide

Environment Settings

When running the C251 Compiler within the µVision IDE, no environment settings are needed. When running the C251 Compiler and utilities from the command prompt, set the following environment variables manually:

VariablePathDescription
PATH\KEIL\C251\BINPath to C251 executable programs.
TMP Path for temporary files generated by the compiler. If the specified path does not exist, then the compiler generates an error and aborts compilation.
C251INC\KEIL\C251\INCPath for C251 include files.
C251LIB\KEIL\C251\LIBPath for C251 library files.

Note

  • Set environment variables using Control Panel — System — Advanced — Environment Variables.
