    Jay,
    the exact definition is
    unsigned char tecla='N';
    in the main C file
    an the declarations are
    extern unsigned char tecla='N';
    in all other c files, and i still have the same problem.
    The "include" files that i initially wanted to debug are now saved as .c files and included in the sourcegroup. This files have pure C code. I don't know what else should i do.
    Thanks a lot

    Javier,

    This problem is again, one that has only to do with basic C programming. Anything that allocates space is a DEFINITION. This means that any place you have an "=" after a variable to initialize it is a definition. So... you need to have the line

    unsigned char tecla='N';

    in only ONE file and then

    extern unsigned char tecla;

    in all the other files that use this variable. If the "=" are in all the files, then the linker will rightfully continue to complain about multiple definitions.

    Thanks a lot jay and you all, finally i made it. As hans said i used a header for the extern an th e declarations in the main. I also worked without the "=", but i don't kwon why because i had already tested that
