Here's how I merged imneme's randutils with her pcg-random generators

randutils_with_pcg.hpp

/*

imneme's pcg-cpp random generator I use:
https://github.com/imneme/pcg-cpp

Here's imneme's blog post describing why randutils.hpp is useful:

/*
imneme's original randutils does not support pcg32 out of the box,
but you can add this to easily support pcg32
*/
namespace randutils
{
	typedef randutils::seed_seq_fe<2, ui32> seed_seq_fe64;
	typedef randutils::auto_seeded<seed_seq_fe64> auto_seed_64;
}

//how to merge randutils with her pcg-cpp
typedef randutils::random_generator<pcg32, randutils::auto_seed_64> pcg32_fe;
typedef randutils::random_generator<pcg64, randutils::auto_seed_128> pcg64_fe;


/*
Here's the simplest way how I use the above:
But I personally recommend creating a class that inherits from pcg32 so you can hide this in a constructor or something.
*/

pcg32 myPcg32 = pcg32_fe().engine();
