FYI: Compiling stand alone programs, another example....

[Douglas Eck]

I am able to compile a stand-alone program linked against liboctave.
I did it on a debian "sid" box.

For future reference, here is the makefile and the program code.
It is similar to other examples on this list, but I found I needed
a couple of different libraries. Note as well that I needed
kpathsea from Octave. I believe this has been mentioned before.

Regards,
Doug Eck


Source Code:
-------------------SNIP----------------------------
#include <octave/oct.h>
int main(void) {
  int sz=20;
  Matrix m = Matrix(sz,sz);
  for (int r=0;r<sz;r++) {
    for (int c=0;c<sz;c++) {
      m(r,c)=r*c;
    }
  }
  cout << "Hello world! " << endl;
  cout << m;
}

Makefile:
--------------------SNIP---------------------------
##Primitive but effective
##Thanks to Paul Kinzele for mkoctver.sh and the Makefile
##I used as an example to generate this one.
