Follow-up Comment #4, bug #60687 (project octave):
The nan package uses the mex interface.
Can you try a basic oct file like examples/code/helloworld.cc:
https://hg.savannah.gnu.org/hgweb/octave/file/97e12df28ee6/examples/code/helloworld.cc
#include <octave/oct.h>
DEFUN_DLD (helloworld, args, nargout,
"Hello World Help String")
{
octave_stdout << "Hello World has "
<< args.length () << " input arguments and "
<< nargout << " output arguments.\n";
// Return empty matrices for any outputs
octave_value_list retval (nargout);
for (int i = 0; i < nargout; i++)
retval(i) = octave_value (Matrix ());
return retval;
}
>> mkoctfile helloworld.cc
>> [x, y, z] = helloworld (1, 2, 3, 4);
Hello World has 4 input arguments and 3 output arguments.
