error c2143: syntax error: missing ')' before 'type'

I have been trying to debug this error for the past few hours with no avail.
When using the following batch file to build my program,

    REM Build process for text editor
@echo off
pushd build
cl /Zi /MDd /IC:UsersGiovannidev_libSDL2-2.0.4include /I"C:Program Files (x86)Microsoft Visual Studio 12.0VCinclude" /I"C:Program Files (x86)Windows Kits8.1Includeshared" ..*.c /link /NODEFAULTLIB:msvcrt.lib /ENTRY:mainCRTStartup /SUBSYSTEM:console /LIBPATH:C:UsersGiovannidev_libSDL2-2.0.4libx64 /LIBPATH:C:UsersGiovannidev_libSDL2_image-2.0.1libx64 SDL2.lib SDL2main.lib SDL2_image.lib /out:text_editor.exe
popd

I get the following error message in CMD:

My entire class is here:

    assert(renderer);

    u32 *screen_pixels = (u32*) calloc(SCREEN_WIDTH * SCREEN_HEIGHT, sizeOf(u32));
    assert(screen_pixels);

    SDL_Delay(3000);

}

(its only 40 lines long)

If you could pleas explain what I am doing wrong (I am new to C), that would be very helpful! Thanks!
