i have developed a code and add a method "AddTwoNo()" in that code and i build it and get static library file (.lib) . but when i use in keil software it return " Not Define AddTwoNo() Method" , i already given declaration of the same method in .H file .
Note:Keil is using other .lib files .
Can any one help me to solve it , is .lib files have more than one format?
