Using std::stoi and std::stod with clang++ in Windows

Question

I am trying to compile some code in Windows with clang++ using this command line

clang++ -std=c++11 *.cpp -Wall

but I get the following:

Datetime.cpp:74:9: error: no member named 'stoi' in namespace 'std'

(I have included in those files)

The code compiles and works fine in Visual Studio 2013. How can I make it work with clang++?

Answer 1

You have to include the <string> header and compile with -std=c++11 or -std=c++14 or anything above that and remember to select the proper standard library with -stdlib=libc++.
