It's using drand48() instead of rand()
r...@botelhor:/usr/ports/lang/perl5.12# make configure |& grep -i rand
drand48_r() NOT found.
random_r() NOT found.
srand48_r() NOT found.
srandom_r() NOT found.
Looking for a random number function...
Good, found drand48().
Use which function to generate random numbers? [drand48]
Checking how to generate random libraries on your machine...
Test results here:
GCC libc:
ga...@botelhor:~/testes> ./test
random value 0.396465
clang libc:
ga...@botelhor:~/testes> ./test
random value -inf
Source of test.c:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
int main() {
printf("random value %f\n", drand48());
exit(0);
}
