[cfe-users] error: non-type template argument depends on a template parameter of the partial specialization

[John Owens]

Greetings!

We’re about to release a graph library for GPUs. The library compiles fine on, well, everything except clang (I’m using OS X), and it’s because clang does not support the same template feature set as other compilers. ("error: non-type template argument depends on a template parameter of the partial specialization")

Here’s the issue and the reply from Duane Merrill at NVIDIA:

https://github.com/gunrock/gunrock/issues/1

(I’ll append a short version of it below.)

What I’d love to know is “is this something that clang will support in the near future / is there an easy clang workaround”. If neither is true, perhaps we do some refactoring, per Duane’s suggestion. But if either is true, that would ease our support issues.

load_tile.cuh:207:

        template <int LOAD, int dummy>
        struct Iterate<LOAD, LOAD_VEC_SIZE, dummy>

The error I'm getting is:

../../gunrock/util/io/load_tile.cuh:207:23: error: non-type template argument
      depends on a template parameter of the partial specialization
