Issue
When installing mingw on a fresh MSYS2 instance I run into the issue of gcc not found:
$ g++ bash: g++: command not found
Setup
Fresh MSYS2 install on relatively clean windows 10 install:
pacman -Syu pacman -Su pacman -S make pacman -S mingw-w64-x86_64-gcc
Diagnostics
It appears that GCC is successfully installed into the directory /mingw64/bin
Yet my path consists of
/usr/local/bin:/usr/bin:/bin:/opt/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:
As such gcc is not found.
I have tried adding /mingw64/bin to the $PATH however this seems like a temporary fix of an underlying problem.
My question specifically is, is there any reason as to why either the mingw is not installed into the /usr/bin/ directory or the installation did not add itself to the path, and or any simple reason as to what is causing this.
Thanks in advance!

Answer
Since you installed mingw-w64-x86_64-gcc it seems like you want to compile 64-bit native Windows applications. Therefore, you should start MSYS2 by running mingw64.exe, found at the top level of your MSYS2 installation. That will put /mingw64/bin/ on your PATH and set some other useful environment variables.
