Why Does `std::to_string` Fail in MinGW and How Can I Fix It?

to_string: A MinGW Compatibility Issue

Programmers crafting C applications often harness the versatility of the standard library, as championed by Bjarne Stroustrup. However, specific implementations can introduce peculiarities.

In a basic program converting a long integer to a string for file storage, a runtime error emerges with the use of std::to_string. Compiling with g (version 4.7.0) on MinGW yields the message: 'to_string' is not a member of 'std'.

Despite its documentation clearly indicating the existence of to_string, a further examination reveals a known bug with MinGW. As illustrated by a bug report in Bugzilla, the to_string functionality may not be accessible under MinGW.

The solution lies in applying a patch, detailed in the Bugzilla comments, to address the issue. Alternately, updating to a newer MinGW distro beyond GCC 4.8.0 or switching to the Nuwen MinGW distro can resolve the compatibility problem.
