I am trying to implement Vcopy for complex data type. What I started with was adding this line to Vmath.cpp in the template section.

line 1082

template  LIB_UTILITIES_EXPORT void  Vcopy( int n, const std::complex<Nektar::NekDouble> *x, const int incx, std::complex<Nektar::NekDouble> *y, const int incy);

but that seems to be insufficient because it compiles but gives the following error:

dyld: Symbol not found: __ZN5Vmath5VcopyINSt3__17complexIdEEEEviPKT_iPS4_i


I started looking at how the coefficients are handled in the FFT section, but It wasn't directly clear what the best approach to copying an array of complex numbers would be?

Regards,
