MinGW won't compile, Error 1

Making a simple hello world app in c++, but it won't compile. I have the folder C:\WiiGames\e3\ with the files main.cpp and Makefile. My makefile is:

build: main.cpp
    C:/MinGW/bin/g++.exe main.cpp -o e3.exe

My error is:

C:\WiiGames\e3>make build
C:/MinGW/bin/g++.exe main.cpp -o e3.exe
make: *** [build] Error 1

C:\WiiGames\e3>

Any help would be greatly appreciated.

My code:

#include <iostream>
#include <stdio.h>
#include <string>
#include <cmath>
#include <cstdlib>
#include <time.h>

int main() {
    printf("Hello World!");
}

g++ -v:

Using built-in specs.
COLLECT_GCC=g++
COLLECT_LTO_WRAPPER=c:/mingw/bin/../libexec/gcc/mingw32/4.6.2/lto-wrapper.exe

Yes, it's an old question. These are some solutions i came across (YMMV a lot):

Check if your paths start with c:/ as opposed to /c/ or vice-versa.

Check if you're running in the right shell, i.e., one of:

  • c:\msys64\msys2_shell.cmd -mingw32
  • c:\msys64\mingw32.exe
  • c:\msys64\usr\bin\bash.exe

which may differ if used within an IDE.

What happens when you run g++.exe main.cpp -o e3.exe on the command line directly? If nothing happens, is g++ in your path? I'd start by making sure that g++ is setup and in your path.

Make sure it is a tab rather than spaces in the make file before the c:/mingw... Line. It looks like it is make giving the error, not g++.
