CUDA: Error while compiling my first cuda program

Question

I am very new to CUDA programming.. I wrote my first code and when I compiled it, it is showing me a lots of error. Can anyone tell me what is wrong

the code

#include <stdio.h> #include "cuda.h" #include <stdlib.h> __global__ void kernel(void) { } int main(int argc, char *argv[]) { kernel<<<1,1>>>(); printf("finished \n"); return 0; }

The errors are

cuda.c:5: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âvoidâ cuda.c:7: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âvoidâ cuda.c: In function âmainâ: cuda.c:12: error: âkernelâ undeclared (first use in this function) cuda.c:12: error: (Each undeclared identifier is reported only once cuda.c:12: error: for each function it appears in.) cuda.c:12: error: expected expression before â<â token

I compiled using

nvcc cuda.c

Can anyone tell me what mistake I am making....

nvcc runs .c files through the normal C compiler. Rename your file to cuda.cu.
