set( CUDA_SEPARABLE_COMPILATION ON )
in cunjunction with
find_package(CUDA 7.5 REQUIRED)
I get a problem in the make command generated for the link with the intermediate object file, especially, the "-ccbin" option that should give to the cuda command line the $CXX variable (in my case).
===================================================
test.cu:
#include "test.cu.h"
#include "thrust/device_vector.h"
void A::doIt()
{
thrust::device_vector<float> a(10,10);
std::cout <<"A = "<<a[0]<<std::endl;
}
===================================================
test.cu.h:
#include <iostream>
class A
{
public:
A()=default;
virtual ~A()=default;
virtual void doIt();
private:
int m_a;
};
===================================================
main.cpp:
#include <cstdlib>
#include "test.cu.h"
int main(int argc, char* argv[])
{
A a;
a.doIt();
return EXIT_SUCCESS;
}
