JavaCL: CLBuildException

Hi,

I'm having a problem with a basic JavaCL example (and with all the other ones aswell). I suppose I should note that I don't have a (sufficient) GPU and that I'm just trying to run my code on CPU (and I'll move on a computer with GPU later on). So this is my host code (it's basically the same as the example from the site):

public class JavacProba {
public static void main(String[] args) throws IOException {

    CLContext context = JavaCL.createBestContext();
    CLQueue queue = context.createDefaultQueue();
    ByteOrder byteOrder = context.getByteOrder();

    int n = 1024;
    Pointer<Float>
        aPtr = allocateFloats(n).order(byteOrder),
        bPtr = allocateFloats(n).order(byteOrder),
        outPtr = allocateFloats(n).order(byteOrder);

    for (int i = 0; i < n; i++) {
        aPtr.set(i, (float)cos(i));
        bPtr.set(i, (float)sin(i));
    }

    // Create OpenCL input buffers (using the native memory pointers aPtr and bPtr) :
    CLBuffer<Float> 
        a = context.createBuffer(Usage.Input, aPtr),
        b = context.createBuffer(Usage.Input, bPtr);

    // Create an OpenCL output buffer :
    CLBuffer<Float> out = context.createBuffer(Usage.Output, outPtr);
    // Read the program sources and compile them :
    String src = IOUtils.readText(new File("TutorialKernels.cl"));
    CLProgram program = context.createProgram(src).build();
    // Get and call the kernel :

    CLKernel addFloatsKernel = program.createKernel("add_floats");

    addFloatsKernel.setArgs(a, b, out, n);
    CLEvent addEvt = addFloatsKernel.enqueueNDRange(queue, new int[] { n });

    outPtr = out.read(queue, addEvt); // blocks until add_floats finished
    // Print the first 10 output values :
    for (int i = 0; i < 10 && i < n; i++)
        System.out.println("out[" + i + "] = " + outPtr.get(i));

}

}

This is my kernel:

__kernel void add_floats(__global float* a, __global float* b, __global float* out, int n)
{
/if(i < n){
int i = get_global_id(0);
out[i] = a[i] + b[i];}/
}

And this is the output I'm getting:

Exception in thread "main" com.nativelibs4java.opencl.CLBuildException: Compilation failure : CL_INVALID_BUILD_OPTIONS (devices: [Intel(R) Core(TM)2 Duo CPU T8100 @ 2.10GHz (ATI Stream)])

at com.nativelibs4java.opencl.CLProgram.build(CLProgram.java:828)
at javacproba.JavacProba.main(JavacProba.java:55)

Java Result: 1

I'm using this version of JavaCL:

javacl-opengl-demos-1.0.0-rc3-shaded.jar

And am running AMD SDK ... Also, I should mention that I can run the same kernel with JOCL, just not with JavaCL.
