Question

I'm using ubuntu 16.04 and I installed gnu octave (4.0.2) through the software center. I can run octave via the shell but I do not get behind how to start if I want to use it in a c++ code. It breaks directly at the beginning by missing the octave header:

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

leads to

/home/analysis/Filter/Filter.cxx:2:10: fatal error: 'octave/octave.h' file not found
#include <octave/octave.h>

I know it is in /usr/include/octave-4.0.2/octave/. How do I get my code to know this ? Thank you very much in advance!

Answer 1

You need to pass the right flags to your compiler. You can use the octave-config program to find them like so:

$ octave-config-4.2.1 -p OCTINCLUDEDIR
/usr/local/include/octave-4.2.1/octave

However, it's easier to use mkoctfile which is what is explained in the manual section about Stand-alone Programs . Like so:

mkoctfile --link-stand-alone standalone.cc -o standalone
