remark: linking in "IQmath_coff.lib" in place of index library "IQmath.lib"

>> Compilation failure

    Hello Puneeth,

    It seems like somewhere you are using calling/using "_main" but this is not declared. Is this something that exists in your code or is it referring to your "void main(void)" function?

    Best regards,
