At first I thought it might be using a C++ standard that is too new or too old, but std::shuffle seems to have been standardized in C++11 and has not been removed since. Hmm. https://en.cppreference.com/w/cpp/algorithm/random_shuffle Still, I'd try compiling again with different compiler flags, might have some luck. Or looking into how std::shuffle is defined in the standard library.
