<pre><span class="quote">> Do you mean if I try to use STL in CUDA?</span >
Yes. Granted, it's a very limited subset that's usable on the GPU side, it
tends to grow as the standard library provides more constexpr APIs with new C++
versions.
<span class="quote">> - NVCC - constexpr is not implicitly __host__ __device__, you need to opt-in via an experimental flag: --expt-relaxed-constexpr</span >
Your example is not compileable with NVCC as it does not allow attribute-based
overloading. Regardless of --expt-relaxed-constexpr NVCC reports that it can't
redefine the function.

I suspect that the root cause of your issues is not whether constexpr functions
are __host__ __device__.</pre>
