Link error when call "GemmStridedBatched<cl_float2>"

[diverger]

Hi,
I need to do complex matrix multiplication, but when I specialize the template function with "cl_float2", it passed compilation, but failed when link. The compiler complain:

undefined reference to `clblast::StatusCode clblast::GemmStridedBatched<cl_float2>....................

So, I guess this function doesn't support complex, or it's a bug.

It should be supported, see the docs. There is also a C version of the function. And the C++ version is compiled here. I guess the issue is that you are using cl_float2 whereas CLBlast uses the C++ data-type std::complex<float>; instead. You can keep your OpenCL buffers of type cl_float2, but the template argument and the value of the alpha and beta parameters should be C++ type, not the OpenCL type.
