c++ - Using std::tr1::normal_distribution in Qt -

i generate numbers normal_distribution in c++11. using qt 4.8 mingw. have added next line

qmake_cxxflags += -std=c++0x

to .pro file , next errors: 'swprintf::' has not been declared 'vswprintf::' has not been declared

tr1 should avoid when using c++11 designed meet limitations of previous standard. (also considered useful went on , became integrated standard.)

luckily there comprehensive random number generation library in c++11 normal distribution.

see here:

#include <random> ::: std::random_device rd; std::normal_distribution<double> dist(0,99); std::mt19937 engine(rd()); double a=dist(engine);

the exact error getting though particular implementation of tr1 isn't anyway. (missing include or missing namespace prefix).
