Hi

We are using 8052 in our project. We are using Keil C51 cross-compiler. Initially, our project code is below 64K. We defined numerical constants in the code as shown:

unsigned char code MAX_LINES = 100;

As the code increased due to more features upgrading, we implemented Code Banking of Keil with 2 code banks. Then, for the numerical constants definition, Keil compiler generated the Error:

Error L104 Multiple Public Definitions

So, We defined numerical constants in the code as shown:

const unsigned char code CA_MAX_LINES = 100; /* For Common area module */

const unsigned char code FB_MAX_LINES = 100; /* For Bank 0 module */

const unsigned char code SB_MAX_LINES = 100; /* For Bank 1 module */

These are defined seperately in the individual header files of the modules, and they are used in almost 150 locations in each file.

This is a single project with common area and 2 code banks. Logically, a single definition must solve the purpose.

Q. How to get rid of the error L104 when defining a single numerical constant, apart from creating 3 individual definitions for each module?

Please suggest.

Thanks in advance
