So I still have some questions... I have tried with a C routine and the pascal unit and program but it doesn't work.

What exactly you done ? It's really trivial task if you know both C and Pascal and thus it's hard to guess where newbie without C knowleadge can fail...

So, I would like to use a beta random deviates I have in C, in my pascal program. I have downloaded "randlib" which contain this function. In randlib.h, there is: extern float genbet(float aa, float bb);

First, I have written beta.p : unit beta; interface function genbet(x,y:real);C; implementation end.

Second, test.p: program betadev; uses beta; begin writeln(genbet(100,150)); end.

Finally, I compile it with gpc and the following message appears: "undefined first referenced symbol in file genbet /var/tmp/cciCa09s1.o ld: fatal: symbol referencing errors No output written to test collect2 : ld returned 1 exit status"

So... What is wrong?

Thanks in advance,

Nathalie
