[CM] incompatible pointer type warnings

Try this:

t_max_err s7_obj_to_max_atom(s7_scheme *s7, s7_pointer s7_obj, t_atom *atom){
    if( s7_is_boolean(s7_obj) ){
        atom_setlong(atom, (int)s7_boolean(s7, s7_obj));

s7_pointer is already a pointer, it doesn't need to be `s7_pointer *obj` in the signature.

Hi Bill and others, I'm trying to clean up the torrent of warnings my project is producing in Xcode now that it's pretty big, and this one has me stumped. here's a snippet of working code:

t_max_err s7_obj_to_max_atom(s7_scheme *s7, s7_pointer *s7_obj, t_atom *atom){

    if( s7_is_boolean(s7_obj) ){

        atom_setlong(atom, (int)s7_boolean(s7, s7_obj));


I get the following warning for every use of s7_obj like the above:

"Incompatible pointer types passing 's7_pointer *' (aka 'struct s7_cell **') to parameter of type 's7_pointer' (aka 'struct s7_cell *'); dereference with *"

If I try letting XCode "fix" it, the compiler things I should be using *s7_obj, which of course crashes (had to try it in case I was totally misunderstanding...)

Is there something I can do to not get this warning, or do I need to figure out how to tell xcode to just shut up with that one?
