Shared library that replaces C rand/srand with std::mt19937 implementation.
This version is designed for UNIX-like systems - if no srand() was called,
it fetches the seed from /dev/urandom, using POSIX API to read it.
The Makefile is somewhat hacky because of -fno-pic. It yields a neat result that is both small and well optimized, but might fail for some compilers.
Builds shared object that links to libc and libgcc_s, but libstdc++ part is included statically.
Tested on GCC 11 (Ubuntu 22.04).
Makefile might be helpful. If it's not, just compile libmtrandom.cpp
as a shared library.
Run a program that uses rand/srand with LD_PRELOAD=libmtrandom.so.
