I don't get the error about a type mismatch for a redeclaration of rect in the code you posted.

However, this is not correct:

#include "d:\kumaracc\button.c"
#include "d:\kumaracc\hvline.c"
#include "d:\kumaracc\label.c"
#include "d:\kumaracc\rect.c"
#include "d:\kumaracc\rmbutton.c"
#include "d:\kumaracc\textbox.c"
 

You do not include source code files in a source code file. This is the same as inserting a copy of the file itself. So if file A.c includes B.c and C.c and B.c also includes C.c you get redefinition errors because there are two copies of C.c and the code will never compile.

Instead you use a project to contain the source files and you use header files to declare functions leaving the linker the job of combining all the object files into your .exe.

You might want to read up on the C/C++ build process.

Do any of those other c files also include rect.c?

By the way, main() should return an int. You should not define it as returning void.
