Error: no matching constructor for initialization of 'std::shared_ptr<uint8_t []>'

Issue

I am trying to use std::shared_ptr <uint8_t []> in my NDK application, but compiler throws below error.

error: no matching constructor for initialization of 'std::shared_ptr<uint8_t []>'

std::shared_ptr<uint8_t[]> x_data(new uint8_t[bytes_to_send]);

My NDK version is r19c and the CMake looks like below

cmake {

           version "3.10.2"

          cppFlags "-std=c++17 -stdlib=libc++ -frtti -fexceptions"
...
}

Solution

According to the libc++ Feature Test Macro Support page, the __cpp_lib_shared_ptr_arrays feature is currently unimplemented.

It may have something to do with this task not having been started according to this page.

---

An alternative in the meantime might be to explicitly specify an array deleter:

std::shared_ptr<uint8_t> x_data(new uint8_t[bytes_to_send], std::default_delete<uint8_t[]>());

(as seen in the documentation here)
