Octave：编译 C++ 文件时找不到 mkoctfile

Question

I am trying to use Octave functions in C++. I install Octave-3.8.0 on Mac OS X 10.9.3 and follow the standalone program example on Octave website ,

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

int
main (void)
{
std::cout << "Hello Octave world!\n";

int n = 2;
Matrix a_matrix = Matrix (n, n);

for (octave_idx_type i = 0; i < n; i++)
  for (octave_idx_type j = 0; j < n; j++)
    a_matrix(i,j) = (i + 1) * 10 + (j + 1);

 std::cout << a_matrix;

return 0;
}

Then I type

      $ mkoctfile --link-stand-alone main.cpp -o standalone

But it shows mkoctfile: command not found. What is the problem?

I also tried to compile the C++ file with g++

     $ g++ -I /usr/local/octave/3.8.0/include/octave-3.8.0 main.cpp

but it shows 2 errors as follows. 1) 'config.h' file not found with include; use "quotes" instead. 2) fatal error: 'hdft.h' file not found.

Please help me!

Answer 1

It may be that octave is not registered in your system properly, judging by the shell response.

Try invoking the command from inside the octave interpreter.

Answer 2

Not sure about on MacOS, but on Linux, mkoctfile is not bundled within the default Octave distribution. Instead, it requires a supplementary package, liboctave-dev , that has to be installed in addition to Octave itself.

This is not documented in the Octave web tutorial.
