Hi @robi56, Could you try to upgrade the gcc version to gcc9.4.0 as "[converter](std::shared_ptr source)......" only supports the higher gcc version. Please refer to https://gcc.gnu.org/projects/cxx-status.html#cxx17 and https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0512r0.pdf for better understanding. Thank you!

Well, the error still occur after I updating the gcc version to 9.4.0. Is there any missing procedures ?
