How to link, and compile, a C++ code using GNU Octave functions?

  • 772

I am new to C++, and I have troubles to get going. I want to re-implement a code, written in GNU Octave, using C++. I would, however, still want to use some GNU Octave functionality in that C++ code.

I have installed GNU Octave 4.0.0 on Ubuntu 14.04 LTS. My problem is that I can not even compile, since the 'octave/oct.h' is missing?

A simple code 

#include <iostream>
#include <octave/oct.h>

using namespace std;

int main ()
{

  Complex number = Complex(0, 1);
  cout << number;

}

when compiled with g++ (4.8.4) produces:

"fatal error: octave/oct.h: Aucun fichier ou dossier de ce type #include compilation terminated.".

Thanks for your help.

    Working with GNU Octave's own minimal example, you should be able to compile and run it without problems using

    $ mkoctfile --link-stand-alone standalone.cc -o standalone
$ ./standalone
Hello Octave world!
 11 12
 21 22

    In order to be able to use mkoctfile, you need to install the liboctave-dev Install liboctave-dev package

    $ sudo apt-get install liboctave-dev
