I need to compile a source with full optimization; however, I get the following error

Command line error D8016: '/ZI' and '/Ox' command-line options are incompatible

the source:


[source lang="cpp"]#include <SFML/System.hpp>#include <algorithm> #include <iostream> void func1() { // generate data const unsigned arraySize = 32768; int data[arraySize]; for (unsigned c = 0; c < arraySize; ++c) data[c] = std::rand() % 256; //std::sort(data, data + arraySize); // test long long sum = 0; sf::Clock clock; for (unsigned i = 0; i < 50000; ++i) //just to see the difference { // primary loop for (unsigned c = 0; c < arraySize; ++c) { //int t = (data[c] - 128) >> 31; //sum += ~t & data[c]; if (data[c] >= 128) sum += data[c]; } } float elapsedTime=clock.getElapsedTime().asSeconds(); std::cout << elapsedTime << std::endl; std::cout << "sum = " << sum << std::endl; std::cin.get();}int main(){ func1();}[/source]

Nothing to do with the source, you're trying to combine compiler optimization flag Ox with debug flag ZI which is invalid. Go into your project options and uncheck the debug flag.

“If I understand the standard right it is legal and safe to do this but the resulting value could be anything.”

There are three options. I tried all of them and still get errors

1)C7 compatible(/Z7) 1>cl : Command line error D8016: '/Ox' and '/RTC1' command-line options are incompatible
2)Program Database(/Zi) 1>cl : Command line error D8016: '/Ox' and '/RTC1' command-line options are incompatible
3)Program Database for Edit and Continue(/ZI) 1>cl : Command line error D8016: '/ZI' and '/Ox' command-line options are incompatible
