Accessing C API (no class from C++ library) from Command line or script

I have a C++ built library in ubuntu which exposes C APIs. Associated header-file defines the APIs without use of 'extern C'. The header file also includes other headerfiles from other packages (Eigen).
- seems cannot use loadlibrary. I tried library-name headerfile-name,i get:
> loadlibrary libfile.so file.h
Failed to preprocess the input file.
Output from preprocessor is:file.h:5:9: warning: #pragma once in main file
#pragma once
^~~~
file.h:7:10: fatal error: Eigen/Core: No such file or directory
#include <Eigen/Core>
^~~~~~~~~~~~
compilation terminated.
- do i need to use other mechanism? (fairly new to matlab)

You haven't answered my question. If the original C++ header files did not have extern "C" in them, why do you think they are not decorated names in the object library file?
