c++ - Crossplatform reproducible number generator -

i need "random" number generator, produces same result given seed on windows, mac, linux, ios , android. tried std::rand , boost::random_int_generator boost::mt19937 sadly result different between windows , mac.

does know of (c++) implementation, works reliably on platforms?

edit 1:

to more specific, diff between numbers boost::mt19937 on windows , mac shows, on windows there (2) additional blocks of numbers being generated. looks strange because majority of numbers same these blocks being present on windows.

edit 2:

boost::mt19937 works reliably on platforms. our problems not bug there.

if don't need too-high-quality rng, can implement one-liner according description here: https://en.wikipedia.org/wiki/linear_congruential_generator linear congruential gens got quite bad name recently, many practical purposes they're fine.

as long you're careful using guaranteed-size types (uint32_t etc.), should fine on platforms.

if need better-quality rng, once again can implement mersenne twister (https://en.wikipedia.org/wiki/mersenne_twister) yourself, more complicated.

yet way use aes (or other block cypher matter, chacha20) in ctr mode (using predefined key) prng; of best known (cryptographic) quality :-). won't take coding on side, you'd need link aes implementation (they're available).

edit: example pseudo-code illustrate crypto-based prng:

class cryptobasedprng {   uint128_t key;  uint128_t count;   cryptobasedprng(whatever-type seed) {    //derive key , initial counter seed    //  we'll using sha256, other split should (like odd bits/even bits of seed)    uint256_t sha = sha256(seed);    key = low_128bits(sha);    count = high_128bits(sha);   }    uint128_t random_128_bits() {     count += 1;//with wraparound     return aes128(key,count);//encrypting 'count' input data aes128 (in ecb mode, if asks mode @ point)   } } 

rather easy , random.
