MinGW not Building and Executing C++

Question

The full error I'm receiving on a simple hello world is, and the code is...

#include <iostream>

int main() {
    std::cout << "Hello, world!";
    return 0;
}

I downloaded MinGW and installed mingw32-base, mingw32-gcc-g++ and msys-base...

I downloaded and installed CodeLite 64 bit and scanned my computer for a C++ compiler in the setup wizard and selected MinGW. MinGW is also in my Path in the Environment Variables.

C:\WINDOWS\system32\cmd.exe /C C:/MinGW/bin/mingw32-make.exe -j4 SHELL=cmd.exe -e -f  Makefile

Does anyone understand why I am unable to build and execute the file?

What is in your makefile? Did you try to compile your sample with g++? — chronoxor

I successfully build your sample with C:\MinGW\bin\g++ test.cpp -o test.exe command.

However I recommend you go with MinGW-w64 which is improved version that supports both 32bit and 64bit compilation.
