Environment Settings

If you run the BL51 Linker within the µVision IDE, you do not need any additional settings on your computer. If you want to run the linker and utilities from the command prompt, you must manually create the following environment variables.

VariablePathDescription
PATH\KEIL\C51\BINPath to the executable programs.
TMP Path to use for temporary files generated by the compiler. If the specified path does not exist, the compiler generates an error and aborts compilation.
C51INC\KEIL\C51\INCPath to the folder for C51 include files.
C51LIB\KEIL\C51\LIBPath to the folder for C51 library files.

Environment variables are entered under Control Panel — System — Advanced — Environment Variables.
