Luigi,

I am using 2005 beta, so maybe it is difernet. All I know is that if you do NOT implement a default constructor my own code does not work.

 

I have experienced sttange things when moving to versions > 6.

 

regards

 

Daniel

Daniel,
        this is strange, since MersenneTwister _does_ have a default 
constructor:

explicit MersenneTwisterUniformRng(unsigned long seed = 0);

Are you saying that in VS > 6, the following won't compile? May you try it?

----------------------------------------
#include <ql/quantlib.hpp>

using namespace QuantLib;

int main() {
        MersenneTwisterUniformRng twister;
        return 0;
}
----------------------------------------

Later,
