Undefined reference to `WinMain@16' while compiling [duplicate]

Question

I just installed Visual Studio Code and was trying to run my code when this came up:

Undefined reference to `WinMain@16' while compiling

I searched through the web for a relevant answer, but none that I found worked.

Here is a more detailed output in the console:

cd "f:\" && g++ testing.cpp -o testing && "f:\"testing
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../libmingw32.a(main.o):(.text.startup+0xa0): undefined reference to `WinMain@16'
collect2.exe: error: ld returned 1 exit status,

By the way, I am using code-runner to run that single file. I have MinGW path all set up—though I don't know if that even matters.

Answer 1

The code runner does not save your code before running it. You can see the commands it executes in the error snippet you have added

cd "f:\" && g++ testing.cpp -o testing && "f:\"testing

So make sure you save your code before running it. This happened with me and I wasted quite some time.
