This is not surprising at all because you haven't initialized the Octave
interpreter. This is not a complete example.

Please compare this code with examples/code/embedded.cc

  
https://hg.savannah.gnu.org/hgweb/octave/file/baa7e37453b1/examples/code/embedded.cc

And compare the equivalent example for Octave 4.2
