NVCC Warning Level

I would like NVCC to treat the warning below as an error:

warning : calling a __host__ function("foo") from a __host__ __device__ function("bar")

The NVCC "NVIDIA CUDA NVCC Compiler Driver" documentation does not even contain the word "warning."

Indication of the CUDA COMPILER DRIVER NVCC Reference Manual, Section 3.2.8. "General tool parameters":

--Werror kindMake warnings about these types of errors. The following is a list of alert types accepted by this option:

cross-execution-space-callBe more stringent about unsupported firewall calls. The compiler will generate an error instead of a warning to call the __host__ __device__to function __host__.

Therefore, do the following:

→ → → CUDA C/++ → → → add --Werror cross-execute-space-call

#include <cuda.h>
#include <cuda_runtime.h>

void foo() { int a = 2;}

__host__ __device__ void test() {
    int tId = 1;
    foo();
}

int main(int argc, char **argv) { }


warning : calling a __host__ function("foo") from a __host__ __device__ function("test") is not allowed


Error   3   error : calling a __host__ function("foo") from a __host__ __device__ function("test") is not allowed
