    Weird Brook+ compiler error

      What does this mean?

      I am trying to compile the following kernel but it gives a weird error. Any help most appreciated.



      kernel void Calculate_critvar (int aout_full[][], double orig_y[], double v_alt[], out double critvar<>, out double ubestt<>, int ndstart, int ndend,
          double sumnode, double nodecnt )
          int2 ind = instance().xy;
          int kv = ind.x;
          int j;
          double d;
          double suml=0.0, sumr;
          double npopl, npopr;
          double critParent = sumnode*sumnode/nodecnt;
          double crit;
              d = orig_y[aout_full[kv][j]];
              suml += d;
              sumr  = sumnode - suml;
              npopl = ((double)j-(double)ndstart)+1.0;
              npopr = nodecnt - npopl;
              if (v_alt[j] < v_alt[j+1]){
                  crit = (suml * suml / npopl) + (sumr * sumr /npopr) - critParent;
                  if (crit > critvar){
                      ubestt = (v_alt[j] + v_alt[j+1])/2.0;
                      critvar = crit;

          Darn, seems that brook+ doesn't like array indices within array indices. I encountered a similar problem that i reported in the bug list, so thought that this might be related.



              index = aout_full[kv][j];

              d = orig_y[index];

          instead of

              d = orig_y[aout_full[kv][j]];

          Solved the problem!


          Thanks for reading
