2D Arrays in local functions

Hello all,
I’m fairly new to OpenCL, and am just now trying to figure out all the semantics but I think I can do some pretty neat stuff with it. I have managed so far to pass an array to a kernel function, make a local copy of it, and pass my local copy to a local (perhaps that’s not the correct term) function for processing.

Now I would like to be able to create a local 2d array inside that local function, but it seems I can’t do that? Or perhaps I haven’t found the syntax that is preferred yet. Here are a few different things I’ve tried:

uint * func1 (uint x[], uint y[]) {
    // Doesn't like this
    uint ** z [5][5];
    // This works...
    uint ** z [5];
    // until this line.
    z[0] = uint[5];

    // This doesn't work either, but I'm not sold there is a "new" keyword
    uint ** z[5];
    z[0] = new uint[5];

    // In a similar fashion this doesn't work either
    uint ** z[5];
    z[0] = &uint[5];

I’m running out of ideas, can anyone help out?

There is no new keyword in OpenCL. So the syntax will always be int oneDArray[100] for a 1D array, int twoDArray[5][5] for a 2D array, etc. Hence you would want to use uint z[5][5][5] I think. You cannot change this at run time.

Thanks, turns out I did something dumb in my host program, so that my opencl code was never correct when trying that… Thanks again.
