Clion无法识别的元组

Question

CLion doesn't seem to recognize c++ tuple s, although I can build and run my program from the terminal.

When trying to build, I only get "Build failed", while all the members of tuple are highlighted and I'm getting "Can't resolve namespace member tuple" (same with tie and make_tuple ).

Here is my simple test:

#include<iostream>
#include<tuple>
std::tuple<int,int> testTuple();

int main(int argc, char** argv) {
    int a, b;
    std::tie(a,b) = testTuple();
    std::cout<<a<<" "<<b;
    return 0;
}
std::tuple<int,int> testTuple()
{
    return std::make_tuple(0,1);
}

My CMakeLists.txt :

cmake_minimum_required(VERSION 2.8)
project(testTuple)
SET(CMAKE_CXX_COMPILER, /usr/bin/g++-4.8)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_BUILD_TYPE Debug)

set(SOURCE_FILES "src/main.cpp")
add_executable(simplification ${SOURCE_FILES})

For implementing such features as code-competition, jump to definitions and so on features CLion has it's own c++ parser. So if your code compiled, but CLion show some kind of errors, go and report bug to jetbrain ( https://youtrack.jetbrains.com/issues/CPP )
