From the GCC documentation

C++0x was the working name of a new ISO C++ standard, which was then released in 2011 as C++11 and introduces a host of new features into the standard C++ language and library. This project seeks to implement new C++11 features in GCC and to make it one of the first compilers to bring C++11 to C++ programmers.

C++11 features are available as part of the "mainline" GCC compiler in the trunk of GCC's Subversion repository and in GCC 4.3 and later. To enable C++0x support, add the command-line parameter -std=c++0x to your g++ command line. Or, to enable GNU extensions in addition to C++0x extensions, add -std=gnu++0x to your g++ command line. GCC 4.7 and later support -std=c++11 and -std=gnu++11 as well.

So, for gcc 4.3 through 4.6 use -std=c++0x, for later version use -std=c++11. Library support for map::emplace was added in gcc 4.8

Nearly all C++11 features are implemented in the GCC 4.6.x . A good place to get latest GCC builds (MinGW) is the TDM website - http://tdm-gcc.tdragon.net/download . It should be easy to replace your current GCC with TDM GCC by overwriting files...

Yeah in fact I just met a very difficult problem that my program was compiled with the mingw32make.

As others already have written, the 32 in mingw32 is a red herring. It used to be standing for 32 bit (when I believe 16 bit was still a thing). Anyhow, nowadays it's just a name, so 'mingw32 API', 'mingw32-make' etc all also work on 64 bit!

So, coming back to the original question: Do you really need an executable that runs on Windows 32bit-only? Note that this is very rare, as Microsoft has been providing 64 bit Windows versions by default since more than a decade IIRC. The latest Windows 11 also doesn't have a 32 bit version anymore (though it seems that you could still install Windows 10 on a 32 bit only machine??).

If you do not need 32 bit actually, please use the mingw1120_64 toolchain that is part of Qt. It also contains a mingw32-make ;)

Install MinGW-w64 gcc (for either 32-bit or 64-bit Windows) via MSYS2's package manager (pacman), or get a standalone build from https://winlibs.com which requires no installation - just unzip (can coexist alongside other MinGW versions).

If you're new to programming in C, I recommend using an IDE, like Code::Blocks for example.
