Hi everyone,
I’m using VC++2008 and CUDA3.0. I can compile and run the SDK stuff just fine, but now I have created a small application that computes some stuff which has both a CPU and a GPU computation option. It compiles without errors or warnings. Whenever I run it though, I get the following access violations (regardless of whether I’m running it as Administrator or as a normal user). These happen before the program even does anything (I set a breakpoint in the first line of main(), but the violation happens while loading libraries, it seems).
I really don’t know why this happens. When I take out the GPU stuff (i.e. when I remove the GPU code and don’t link cudart into the project) everything is fine and works as expected. I have compared my build configuration with the ones that the SDK projects have and the only thing that’s different is that I’m using CLR (Common Language Runtime) since I’m using Windows Forms (and hence .NET), but that shouldn’t hurt, right?
Any help/ideas are appreciated a lot.
