Hi,
i wrote a program in D in win32 (commandline), and it works fine.
then i decided i would try and compile it using the linux port of D from
www.opend.org
it works, but only if i comment out my usage of getUTCtime().
the error message is this:


passGen.o: In function `__endif_599':
passGen.o(.text+0x30ff): undefined reference to `_D4date_10getUTCtime_FZl'
collect2: ld returned 1 exit status

what im using it for, is to further randomise the random seed when creating the
random number generator.
is there a way i can make getUTCtime() work in linux? or some other time
function i can use that will work? or even some other method of getting a unique
number for the rand_seed() func?
thanks,

Nick

One popular way is to use the chip cycle counter:

ulong read_timer()
{
    asm
    {    naked;
          rdtsc;
    }
}
