I have just installed Qt Creator and am using C++11 syntax.
Unfortunately when I try to build my project I get:
/usr/include/c++/4.8/bits/c++0x_warning.h:32: error:
#error This file requires compiler and library support for the ISO C++ 2011
standard. This support is currently experimental, and must be
enabled with the -std=c++11 or -std=gnu++11 compiler options.
#error This file requires compiler and library support for the \
^
Then a bunch of errors like "tuple
not a member of std
".
My CMakeLists.txt contains:
project(routing_tests)
set(QMAKE_CXXFLAGS "-std=c++11")
cmake_minimum_required(VERSION 2.8)
aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})
EDIT: Tiny test case showing the issue https://gist.github.com/anonymous/8171073
#include <iostream>
#include <tuple>
int main() {
auto foo = std::make_tuple("bar", "foo", "can");
std::cout << std::get<0>(foo) << std::get<1>(foo) << std::get<2>(foo);
}
project(tuple_tests)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
# C++14: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++1y")
cmake_minimum_required(VERSION 2.8)
aux_source_directory(. SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})
