I compile my program with the module builder and I
get the following warnings:

ccom: Warning: unformat_to_3dLat.c, line 87: Argument 3 Type Doesn't Match prototype description; prototype: pointer to pointer to void is different from actual: pointer to pointer to int
        cxLatPtrGet(lattice_2d, 0, &int_ptr, 0, 0);

Are these warning bad? 
Any ways to eliminate the warnings?

Thanks in advance.
