I am trying to make the to_string(NUMBER)
function work in my Ubuntu computer for weeks but it never ever works in the QT environment or anywhere else. My code works perfectly on my Mac osx, but when I try running it in Ubuntu it complains that to_string
is not declared in scope. Any solutions to this would be greatly appreciated. I have tried to update the gcc compiler but it didn't fix the problem. Please help.
I am using QT Creator 4.8.1 and I am using C++ and latest version of Ubuntu.
int Bint::operator*(int temp){
Bint b(to_string(temp));
return ((*this)*b);
}
I was missing the QMAKE_CXXFLAGS += -std=c++0x in the pro file.
There could be different reasons why it doesn't work for you: perhaps you need to qualify the name with std::
, or perhaps you do not have C++11 support.
This works, provided you have C++11 support:
#include <string>
int main()
{
std::string s = std::to_string(42);
}
To enable C++11 support with g++ or clang, you need to pass the option -std=c++0x
. You can also use -std=c++11
on the newer versions of those compilers.
