Why Doesn't My MinGW g Compiler Recognize the `to_string()` Function?

to_string Function Not Recognized in g with MinGW

Problem:

When attempting to use the to_string() function from the standard C library in a program, an error is encountered: "'to_string' is not a member of 'std'." This occurs despite using the -std=c 0x flag to enable C 0x features.

Cause:

This is a known bug specific to MinGW implementations of g .

Solution:

Option 1: Update MinGW

The issue has been resolved in MinGW-w64 distributions higher than GCC 4.8.0 or in Nuwen MinGW. Upgrade to one of these versions.

Option 2: Apply a Patch

A patch can be found in the comments section of this Bugzilla report: https://sourceforge.net/p/mingw/bugs/1735/

Details:

The to_string() function is defined in the header in the C standard library, but it was not included in MinGW implementations prior to GCC 4.8.0. The -std=c 0x flag only enables C 0x language features and is not sufficient to enable newer standard library features such as to_string() in MinGW.

Applying the patch or updating to a newer MinGW version will resolve the issue and allow you to use the to_string() function.
