Bug ID: 44803
Summary: "dynamic initialization is not supported" when
compiling CUDA + Thrust code
Product: clang
Version: 9.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: CUDA
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
When compiling the following piece of code with on Windows:
```
#include <thrust/device_vector.h>
#include <thrust/transform.h>
#include <thrust/iterator/counting_iterator.h>
#include <thrust/copy.h>
using namespace thrust;
int main()
{
int size = 100;
device_vector<int> v(100);
auto counter = make_counting_iterator(0);
copy(counter, counter + size, v.begin());
auto multiply = [] __host__ __device__ (const int&x){ return x * x;};
transform(v.begin(), v.end(), v.begin(), multiply);
}
```
I get the following series of errors:
```
thrust/functional.h:1452:74: error: dynamic initialization is not supported for
__device__, __constant__, and __shared__ variables.
static const __device__ thrust::detail::functional::placeholder<0>::type _1;
thrust/functional.h:1461:74: error: dynamic initialization is not supported for
__device__, __constant__, and __shared__ variables.
static const __device__ thrust::detail::functional::placeholder<1>::type _2;
...
thrust/functional.h:1533:74: error: dynamic initialization is not supported for
__device__, __constant__, and __shared__ variables.
static const __device__ thrust::detail::functional::placeholder<9>::type _10;
```
I used the latest release of Thrust.
I checked the type being initialized and it looks like it has no data and an
empty constructor.
