Newbie issue probably ?

Question

Hi,
I was trying to play for the 1st time with flascc following https://github.com/adobe-flash/crossbridge/wiki/Using-C---code-for-path-finding-in-your-Ac tionScript-game to understand how to create a swc as I want to create an optimized version of the Math.sqrt() I could use in Flex.
The point is arriving at "Making the SWC more AS3 friendly" and creating a Flex 4.9.1 project when I type "flascc_", a lot of functions apprears in the list except the one created (move, createPather, etc...) I double checked I copy/paste all the code indicated.
So, I wonder, can I use the generated swc with other versions than SDK 4.7 ? If yes, how ?
I haven't been able to get the pathFinder.zip supposed to contain all the sample files, someone knows where I can get it ?
Thanks,
-Fred

Answer 1

Following the doc linked above, I had this error: [PathFinderAS3Project]: Error code: 1180: Call to a possibly undefined method flascc_createPather.
I created another swc for my custom MathUtil.squareRoot function but the result was the same, same kind of errors I mean with this as3api.cpp:
#include "MathUtil.h"
#include "AS3/AS3.h"
// First we mark the function declaration with a GCC attribute specifying the
// AS3 signature
////** flascc_createMathUtil **////
void flascc_createMathUtil() __attribute__((used,
    annotate("as3sig:public function flascc_createMathUtil():int"),
    annotate("as3package:com.doublefx.flascc_interface")));
void flascc_createMathUtil()
    // Create an instance of the Class
    MathUtil *result;
    result = (MathUtil *)new MathUtil();
    // Create int for the pointer into memory for this object instance
    AS3_DeclareVar(asresult, int);
    AS3_CopyScalarToVar(asresult, result);
    // return the pointer value of this object in memory
    AS3_ReturnAS3Var(asresult);
////** flascc_deleteMathUtil **////
void flascc_deleteMathUtil() __attribute__((used,
    annotate("as3sig:public function flascc_deleteMathUtil(self):void"),
    annotate("as3package:com.doublefx.flascc_interface")));
void flascc_deleteMathUtil()
    MathUtil *mathUtil = (MathUtil *) 0 ;
    AS3_GetScalarFromVar(mathUtil, self);
    delete arg1;
    AS3_ReturnAS3Var(undefined);
////** flascc_squareRoot **////
void flascc_squareRoot() __attribute__((used,
    annotate("as3sig:public function flascc_squareRoot(self, x:int):Number"),
    annotate("as3package:com.doublefx.flascc_interface")));
void flascc_squareRoot()
  int arg1 ;
  double result ;
    AS3_GetScalarFromVar(arg1, n);
  result = (double)sqrt(arg1);
    AS3_DeclareVar(asresult, Number);
    AS3_CopyScalarToVar(asresult, result);
    AS3_ReturnAS3Var(asresult);
So, I tried to go by Swig.
MathUtil .h:
class MathUtil {
public:
          double sqrt(int n);

So, I tried to manually removed the duplicated MathUtil class definition and force the make to continue but I had :

I hope I've been clear enought, any thoughts ?
