Hello. I'm new in OpenCL. I would like to take advantage of vector data types (like float4...). I'm working with NBody problem and would like to store location and charge of particles in 1D array of float4 (like struct -> x, y, z, charge). I've included in my main program library like this: #include <vecLib/vecLib.h> But it seems like it doesn't work this way. Have I forgotten anything? Is there anything else I need to include so that float4 would work?
