SDL2 Msys2 Windows X64 构建

如何解决SDL2 Msys2 Windows X64 构建

尝试使用最新的 MSYS 在 Windows 上构建 SDL2-2.0.14。

如果我尝试使用根 SDL 目录中的最小 makefile 进行构建，则会出现以下错误：

cc -g -O2 -I./include   -c -o src/timer/dummy/SDL_systimer.o src/timer/dummy/SDL_systimer.c
cc -g -O2 -I./include   -c -o src/video/SDL_RLEaccel.o src/video/SDL_RLEaccel.c

解决了在 include/SDL_config_windows.h:269 中删除 OPENGL 支持的问题：

#ifndef SDL_VIDEO_OPENGL_EGL
/* #define SDL_VIDEO_OPENGL_EGL    1  commented for wind64 build */
#endif

现在我有 libSDL.a 文件，但是如果我尝试从 test 文件夹构建一个测试：

我需要链接其他东西吗？
