Error

Hi,

i download source on 30 may 2009

Here is the error i get when i compile

C:\upp\uppsrc\Geom\geometry.cpp: In function 'double Upp::Bezier2Length(Upp:ointf, Upp:ointf, Upp:ointf, double)':
C:\upp\uppsrc\Geom\geometry.cpp:55: error: 'ScalarProduct' was not declared in this scope
C:\upp\uppsrc\Geom\geometry.cpp:56: error: 'VectorProduct' was not declared in this scope

Please tell what is going wrong.

Regards

What platform are you compiling under please? This error sounds familiar but I haven't seen it recently. I suspect that you can just comment out the two lines but I'd like to know under what circumstances this error ocurrs so I can try to stop it in future.
Cheers,
Nick

Hi Nick,

Thanks for reply.

I use Windows Xp SP2 , U++ 2008 , Plugins (z , tiff, geotiff ) from the link provided on source download page.

its in geometry.cpp, commenting out will not solve the problem. Please see

{
 Pointf v = b - a, w = (c - b) - v;
 v *= 2;
 double w2 = Squared(w);
 if(fabs(w2) <= 1e-100)
  return t * Distance(c, a);
 double k = ScalarProduct(v, w) / (2 * w2);
 double d = fabs(VectorProduct(v, w)) / (2 * w2);
 double wl = sqrt(w2);
 double x = t + k;
 if(fabs(d) <= 1e-100)
  return wl * x * fabs(x) / 2;
 return wl * (x * hypot(x, d) + (d * d) * argsinh(x / d));
} 

there are comments in geometry.cpp

// temporary fix by Mirek Fidler:
//inline double ScalarProduct(Sizef a, Sizef b) { return a.cx * b.cx + a.cy * b.cy; }
//inline double VectorProduct(Sizef a, Sizef b) { return a.cx * b.cy - a.cy * b.cx; }

if i uncomment it, i get error for previous defined function. it is in Core

 friend T      ScalarProduct(Size_ a, Size_ b) { return a.cx * b.cx + a.cy * b.cy; }
 friend T      VectorProduct(Size_ a, Size_ b) { return a.cx * b.cy - a.cy * b.cx; }

I comment out these and uncomment the fix by Mirek Fidler. i get error

C:/upp/examples/openWind/RasterLayer.cpp:2424: undefined reference to `Upp::Value::Value(long)'
I comment out original string and use "test" to gt

// String s = Format("Failed to initialise the grid: left=%f,right=%f,top=%f,bottom=%f,nX=%d,nY=%d,resX=%f,resY=%f",
//       rc.left,rc.right,rc.top,rc.bottom,nX,nY,resX,resY);
  String s = "Failed to initialise the grid";

It go built but please suggest the better way.

thanks

Hi nick,

sorry that i have more to tell. Its related to the above post

After successful build or release the exe doesnot run. dbl clk on openwind.exe produces no effect.I tried on other system also.

I use standard build method with MinGW Optimal.

OCOE and all others donot build , give errors.

Also from IDE,  Execute doesnot work. (windows running process list doesnot have openwind.exe.it is there when i click  

"run in debugger" but its UI doesnot show ) 

Regards

Yeah I can't get it to work under MinGW either but then I use MSC9 under Windows.

Try using MSC9 with SDKv6.1 both downloadable for free from Microsoft.
