Why Doesn't My MinGW G Compiler Recognize std::to_string()?

to_string Not Recognized by G (MinGW)

When trying to convert a long integer to a string using std::to_string(), some G users encounter an error claiming "to_string" is not a member of "std". This issue particularly arises with MinGW.

Ursache

This behavior is known to be a bug in MinGW distributions. The corresponding Bugzilla report provides a patch to resolve the issue.

Lösung

To fix the problem, follow one of the approaches below:

1. Update MinGW Version

Upgrade your MinGW installation to a version higher than GCC 4.8.0 provided by the MinGW-w64 project. This project provides toolchains for both 32-bit and 64-bit systems.

2. Install Alternative MinGW Distro

Install an alternative MinGW distribution such as Nuwen MinGW, which resolves this issue.

3. Patch Current MinGW Installation

Apply the patch provided in the Bugzilla comments to make the to_string() function available in your current MinGW installation.
