Details:
In MATLAB, the mexfunction has highest priority. In Octave my code errors out
with a max recursion limit error. Looks like m-file has priority over
mexfunction.
1. Create a directory @testme with the following files.
2. At Octave prompt: >> testme
3. >> testme
g++ -c -fPIC -I/usr/local/include/octave-5.2.0/octave/..
-I/usr/local/include/octave-5.2.0/octave -I/usr/local/include -pthread
-fopenmp -flto -s -fomit-frame-pointer -march=native -I. -DMEX_DEBUG
/home/work/octave/@testme/testme.cpp -o /tmp/oct-3Gdij3.o
g++ -I/usr/local/include/octave-5.2.0/octave/..
-I/usr/local/include/octave-5.2.0/octave -I/usr/local/include -pthread
-fopenmp -flto -s -fomit-frame-pointer -march=native -shared -Wl,-Bsymbolic
-o /home/mark/octave/@testme/testme.mex /tmp/oct-3Gdij3.o
-L/usr/local/lib
error: max_recursion_depth exceeded
error: called from
testme at line 10 column 8
4. Incidentally the clickable link in the error message brings up the wrong
file.
++ver
testme.m
function output = testme(varargin)
mexbin = [mfilename('fullpath') '.' mexext];
if ~exist(mexbin,'file')
mexcpp = [mfilename('fullpath') '.cpp'];
mex('-v',mexcpp,'-output',mexbin);
end
output = testme(varargin{:});
testme.cpp
#include "mex.h"
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <iostream>
void mexFunction(int nlhs, mxArray * plhs[], int nrhs, const mxArray *
prhs[])
{
std::cout << "testme cpp" << std::endl;
}
