Cross compile with i686-w64-mingw32-g++ and use main() as entry point

I am compiling for Linux in a make target using plain g++ for my linux executable and for windows in a separate make target using i686-w64-mingw32-g++. If I use main(), the g++ target builds and the windows target fails with:

./build/i686-w64-mingw32-i686-w64-mingw32-crt/./mingw-w64-crt/crt/crt0_c.c:18: undefined reference to `WinMain@16'

I tried the two solutions from the link above, but neither worked.

Here is my windows build target:

RayCaster1.cpp SDLWrapper.cpp -I/usr/local/i686-w64-mingw32/include -L/usr/local/i686-w64-mingw32/lib -lmingw32 -lSDL2 -lSDL2_ttf -static-libgcc -static-libstdc++ -Wl,-Bstatic -lstdc++ -lpthread -Wl,-Bdynamic -o testWindows.exe

Adding -mwindows or -Wl,-subsystem,windows did not solve the problem for me. I tried putting one of them at a time at the end, beginning, middle. My windows build target has become really bloated, am I borking it with another flag?

Here is my main function:

int main(int /*argc*/, char */*argv*/[])
{
    SDLWrapper sdlWrapper;

    initRasterPixels();
    sdlWrapper.setupSDLRenderer(WINDOW_WIDTH, generateRaster);
    return 0;
};

Use -mconsole instead of -mwindows.
