Cxx.jl converting between Julia Complex and std::complex

Question

I'm currently using Cxx to allow Julia code to interact with a C++ library. Part of what I want to do is to efficiently pass collections (typically vectors) of complex data in both directions. That is, I'd like something along the lines of:

cv = [1 + 2im, 0 - 1im, ..., 1 + 0im]
cxxv = convert(cxxt"std::vector<std::complex<int>>", cv)
new_cv = icxx"process_complex_vector($cxxv);"
# do some stuff with new_cv

Any suggestions?

Answer 1

My impression is that Cxx.jl is not well maintained and that if you're serious about wrapping a C++ lib, you should use CxxWrap.jl. I tried to use Cxx to wrap a library and gave up. Your results may vary.

That said, it may be that Keno would respond better on the Julia slack.
