There are three main versions of the MingW:

1- mingw32-gcc.exe the compiler will build 32-bit applications on 32-bit systems.

2- i686-w64-mingw32-gcc.exe the compiler will build 32-bit applications on 64-bit systems.

3- x86_64-w64-mingw32-gcc.exe the compiler will build 64-bit applications on 64-bit systems.

of course, more details arise once you read the documentation. ensure you are installing the correct version.

Pre-built Toolchains - mingw-w64
LLVM-MinGW is a toolchain built with Clang, LLD, libc++, targeting i686, x86_64, arm and aarch64 (ARM64), with releases both for running as a cross compiler from Linux and for running on Windows. It supports Address Sanitizer, Undefined Behaviour Sanitizer, and generating debug info in PDB format.

As of 2009-05-31, x86_64-pc-mingw32 has been replaced by x86_64-w64-mingw32. The change allows for mingw-w64 to have a host/target type independent of mingw.org's MinGW. All default libraries work! We are now in a functional beta stage. This file describes how to build the Mingw-w64 GCC toolchain ...

Linux to Windows: x86_64-w64-mingw32-gcc will not compile a 64-bit executable, how can I resolve this? - Stack Overflow
Also, for the record, the default gcc native to my Debian system works perfectly well with the -m32 and -m64 commands so it's not like my system isn't capable of it and... in fact, if anything, I would expect the behavior to be backwards as Linux seems to require special set-up to do 32-bit builds or run 32-bit programs on a 64-bit machine. For the last attempt to understand the problem myself I ran the command x86_64-w64-mingw32-gcc -v -o hello.exe hello.c hellofunc.c -I .

Most checks in binutils, gdb, gcc, etc (and all their testsuites) are still using mingw32[1]. To install the MinGW toolchain, prepare the system with a crossdev environment: root #emerge --ask app-eselect/eselect-repository sys-devel/crossdev ... We use a target descriptor to tell crossdev what to build: $outputarch-$runtime-mingw32. Throughout this article, the 32-bit toolchain has $outputarch == i686, the 64-bit toolchain has $outputarch == x86_64. Since only MinGW-w64 is used as the runtime, it is assumed $runtime == w64.
