Boost bootstrap throwing errors - c++

Question

Premise: I'm new to this. Anyway, I'm trying to bootstrap the boost library through the command bootstrap.bat mingw. As you guessed, I'm on windows 64-bit and using the MinGW toolchain. But when I run the command, the output is

Answer 1

Download MinGW_w64 instead.
Looks like support for MinGW has dropped while boost has continued active. For latest versions of boost use MinGW_w64.
I removed MinGW path and added a new MinGW_64 containing the files from https://winlibs.com/#download-release in C:\MinGW_64 and added to PATH. Could build the b2.exe afterwards.
