Seth,

Take a look at the source code to the CUDA 3.0 wrapper I just finished. You have some mistakes in your coding and this should help provide you a better example. When I first was coding the CUDA 2.0 wrapper some people told me to look at opengl and how it was wrapper to the linux library so that is how I came up with this.

http://shelnutt2.host56.com/wrapper.tar.gz

Generally the specfile goes like

@  stdcall cudaGetDeviceProperties( ptr long ) wine_cudaGetDeviceProperties

Then in your .c file:

cudaError_t WINAPI wine_cudaGetDeviceProperties(
struct cudaDeviceProp *prop, int device) {
    WINE_TRACE("\n");
    return cudaGetDeviceProperties(prop, device);
}


Also your linking looks off. You shouldn't be linking -l"." . You need to specify the exact file, like for CUDA we did -lcudart or -lcufft.

I hope that help you some.
