#181322 - Fundamental 'C' programming error! Responding to: ???'s previous message |

... We defined numerical constants in the code ... These are defined seperately in the individual header files of the modules, and they are used in almost 150 locations in each file. That is a fundamental 'C' programming error - nothing to do with Keil or banking! You should not place data definitions in header files! If a header file contains definitions, and you #include it in more than one (ie, multiple) .c files, then that will give you a definition in each .c file - ie, multiple definitions!! Your headers should contain only extern declarations; Each definitions should be in exactly one .c source file. http://c-faq.com/decl/decldef.html |
