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.
| Variable | Path | Description |
|---|---|---|
| PATH | \KEIL\C51\BIN | Path 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\INC | Path to the folder for C51 include files. |
| C51LIB | \KEIL\C51\LIB | Path to the folder for C51 library files. |
For Windows NT, Windows 2000, and Windows XP, environment variables are entered under Control Panel — System — Advanced — Environment Variables.
For Windows 95, Windows 98, and Windows ME, the settings are placed in AUTOEXEC.BAT using the following commands:
PATH=C:\KEIL\C51\BIN;%PATH% SET TMP=D:\TMP SET C51INC=C:\KEIL\C51\INC SET C51LIB=C:\KEIL\C51\LIB
