[Dev-C++] Re: linking problem

[Horst R. <hr...@un...>]

Hi Ioannis,

of course, there is one. I have the code truncated.
Here the first part of it. 

[...] 

arrhenius::arrhenius()
{
} 

bool arrhenius::calc()
{
 for (int i = 0; i < K; i++)
 {
   for (int j = 0; j < aN[i]; j++)
   {
     aSY[i]  += aY[j][i];
     aSSY[i] += sqr(aY[j][i]);
   } // for j
   aMean[i] = aSY[i] / zw.M;
   zw.SY   += aSY[i];
   zw.SX   += aN[i] * aX[i];
   zw.SSX  += aN[i] * sqr(aX[i]);
[...] 

the code is very long. The project is just at the begin.
There are oly link errors but no compiler errors.
Horst 

PS: from now I will write to the list from a new e-mail adress: 
h.r...@gm.... This subscription will be closed. I subscribed today on 
the new adress,
