Unable to interpret fixed size array, matlab compiler

I have two lines of c++ code that I'm trying to interface through matlab. (1) does not work, but (2) works - why is that? I need to use (1).

(1)

typedef unsigned short uint16;
const uint16 kLevels = 256;
bool SetTable(const float (*newLut)[kLevels]);

(2)

enum
{
  kLevels = 256;
};
bool SetTable(const float (*newLut)[kLevels]);

matlab calling routine:
table1 = zeros(1,256);
[flag] = calllib(libName,'SetTable', single(table1));

error is:

Error using loadlibrary (line xxx)
: error
C2057: expected constant expression
: error
C2466: cannot allocate an array of constant size 0

I have no problem using the uint16 in other places. Is the compiler not understanding this function definition?

You wrote

const unit16 kLevels = 256;

instead of

const uint16 kLevels = 256;

Sorry..that was a typo while asking the question. I have corrected the spelling mistake. The question still stands
