I am desperately trying to install the latest version of mingw-w64 to get acess to gcc 10 on windows 10. I used the online installer for mingw-w64 in the past, but it is still stuck in 2018 on 8.1... More on stackoverflow.com

Here's a step by step flow- Go to winlibs.com Scroll down and find the "UCRT runtime" Download the "Zip archive" for Win64 (you can choose to download the one without clang) Extract the mingw folder from zip and place it somewhere Open mingw folder, there's a bin folder, open it Copy the current path, e.g., "C:\mingw\bin" Open environment variables editor Open Path, add new and paste the above copied path You're done More on reddit.com

I have the "Msys64" package installed. It uses "pacman" to do installation and updates. Hope you've memorized the switches. The main problem with that distribution is that there can be confusion as to which shell you need to run to get things done: "mingw32" shell "mingw64" shell "msys2" shell You'd think that "mingw64" and "msys2" would provide the same C compiler environment, but they do not. The "msys2" is intended on building applications that run under the "msys2" shell, and not for general use. The Windows headers that are included by the "msys2" GCC compiler are incompatible with standard Windows headers. As for how to install the compilers, if you literally ask for just "gcc", you get the MSYS2 version of GCC, not the Mingw64 version of "gcc", so you get broken Windows headers, unless you knew in advance not to download the "gcc" package.

It also has QtCreator IDE as the only IDE I've found so far in which open source integrated debugging actually works. (C::B is a joke) More on reddit.com
