Bwconncomp code conversion in c++ using matlab coder gives error

Question

Bwconncomp returns a variable with 4 fields. one of them is pixelIdxlist which is of type cell array. For code conversion, We have to allocate the memory to variable beforehand. While allocating memory, Matlab coder gives an error "Code generation does not support cell arrays in structure fields.","This structure does not have a field 'PixelIdxList'." How can I resolve these errors. Here's my code:

    n=14456;
    A = ones(1,n);
    sz = size(A);
    p = cell(sz);
    field6='PixelIdxList';  value6 ={p};
    CC = struct(field3,value3,field4,value4,field5,value5,field6,  value6 );
    CC = bwconncomp(I3);
    A=NaN(9999,1);
    for i = 1:size(CC.PixelIdxList,2)
        A(i) = size(CC.PixelIdxList{i},1);
    end
    [Val,Idx] = max(A);
    L = zeros(CC.ImageSize);
    for k = 1 : CC.NumObjects
        L(CC.PixelIdxList{k}) = k;
    end
    L(find(L~=Idx))=0;
    L(find(L==Idx))=1;
   %continue....
