我尝试使用mingw（最新版本）和SDL2-devel-2.0.2-mingw来编写简单SDL2的lazyfoo教程。 我使用这个编译命令：
G:\dev\cpp\SDL\tests_mingw\01_hello_SDL\01_hello_SDL>g++ -g 01_hello_SDL.cpp -IC:\Dev64\mingw_libs\include\SDL2 -LC:\Dev64\mingw_libs\lib -w -Wl,-subsystem,windows -lmingw32 -lSDL2main -LSDL2 -o
01_hello_SDL.exe
我收到这些链接器错误：

我在这里做错了什么？
我正在使用32位编译。
