Member access into incomplete type error

by

You’re asking for a member in the FooEncoder struct which isn’t visible anywhere in your foo_interface.cc file. This looks similar to a pimpl idiom.

In order to have your code aware of FooEncoder‘s structure you need to either

#include "foo_encoder.c"

in your foo_interface.cc file (I quite don’t like this solution and you didn’t post the full code either) or move your struct definition elsewhere in a header file and include that one (recommended).
