Ik heb zelf  gevonden wat ik zocht, echter kleine probs met compiler :

random.cpp :
#include <iostream>
#include <RndInt.h>
#include <RNG.h>

int main() {
 RNG *gen;
 RandomInteger a(gen);
 int b=a.asInt();
 cout << b << endl;
 return 0;
}

waarop de compiler zeer cryptisch antwoord :

linux-prompt > g++ rnd.cpp -o rnd

/tmp/ccdLXHJk.o: In function `main':
/tmp/ccdLXHJk.o(.text+0x12): undefined reference to
`RandomInteger::RandomInteger(RNG *)'
/tmp/ccdLXHJk.o(.text+0x21): undefined reference to
`RandomInteger::asInt(void)'
collect2: ld returned 1 exit status

Wat gaat hier fout ??
