在[原]SDL开发教程我们知道了如何在pc下使用SDL进行开发，在android上面是否一样可以使用呢？答案是肯定的。
下面我们进行移植SDL到Android，这里都是基于SDL最新版进行移植的，在Eclipse中编译。
开发环境：Ubuntu 14.04 64位，Eclipse + CDT + ADT，NDK
一、到官网下载http://www.libsdl.org/hg.php 下载2.0的源码也可以通过hg来clone最新的源码
hg clone http://hg.libsdl.org/SDL
二、编译SDL
进入到下载的文件SDL2-2.0.3中将android-project导入到Eclipse中，进入jni文件夹，新建一个SDL文件，将SDL2-2.0.3\src 、SDL2-2.0.3\include、SDL2-2.0.3\Android.mk文件拷贝到android-project\jni\SDL\中。
android-project\jni\SDL\Android.mk文件内容如下：
LOCAL_PATH := $(call my-dir) ########################### # # SDL shared library # ########################### include $(CLEAR_VARS) LOCAL_MODULE := SDL2 LOCAL_C_INCLUDES := $(LOCAL_PATH)/include LOCAL_EXPORT_C_INCLUDES := $(LOCAL_C_INCLUDES) LOCAL_SRC_FILES := $(subst $(LOCAL_PATH)/,, $(wildcard $(LOCAL_PATH)/src/*.c) $(wildcard $(LOCAL_PATH)/src/audio/*.c) $(wildcard $(LOCAL_PATH)/src/audio/android/*.c) $(wildcard $(LOCAL_PATH)/src/audio/dummy/*.c) $(LOCAL_PATH)/src/atomic/SDL_atomic.c $(LOCAL_PATH)/src/atomic/SDL_spinlock.c.arm $(wildcard $(LOCAL_PATH)/src/core/android/*.c) $(wildcard $(LOCAL_PATH)/src/cpuinfo/*.c) $(wildcard $(LOCAL_PATH)/src/dynapi/*.c) $(wildcard $(LOCAL_PATH)/src/events/*.c) $(wildcard $(LOCAL_PATH)/src/file/*.c) $(wildcard $(LOCAL_PATH)/src/haptic/*.c) $(wildcard $(LOCAL_PATH)/src/haptic/dummy/*.c) $(wildcard $(LOCAL_PATH)/src/joystick/*.c) $(wildcard $(LOCAL_PATH)/src/joystick/android/*.c) $(wildcard $(LOCAL_PATH)/src/loadso/dlopen/*.c) $(wildcard $(LOCAL_PATH)/src/power/*.c) $(wildcard $(LOCAL_PATH)/src/power/android/*.c) $(wildcard $(LOCAL_PATH)/src/filesystem/dummy/*.c) $(wildcard $(LOCAL_PATH)/src/render/*.c) $(wildcard $(LOCAL_PATH)/src/render/*/*.c) $(wildcard $(LOCAL_PATH)/src/stdlib/*.c) $(wildcard $(LOCAL_PATH)/src/thread/*.c) $(wildcard $(LOCAL_PATH)/src/thread/pthread/*.c) $(wildcard $(LOCAL_PATH)/src/timer/*.c) $(wildcard $(LOCAL_PATH)/src/timer/unix/*.c) $(wildcard $(LOCAL_PATH)/src/video/*.c) $(wildcard $(LOCAL_PATH)/src/video/android/*.c) $(wildcard $(LOCAL_PATH)/src/test/*.c)) LOCAL_CFLAGS += -DGL_GLEXT_PROTOTYPES LOCAL_LDLIBS := -ldl -lGLESv1_CM -lGLESv2 -llog -landroid include $(BUILD_SHARED_LIBRARY) ########################### # # SDL static library # ########################### LOCAL_MODULE := SDL2_static LOCAL_MODULE_FILENAME := libSDL2 LOCAL_SRC_FILES += $(LOCAL_PATH)/src/main/android/SDL_android_main.c LOCAL_LDLIBS := LOCAL_EXPORT_LDLIBS := -Wl,--undefined=Java_org_libsdl_app_SDLActivity_nativeInit -ldl -lGLESv1_CM -lGLESv2 -llog -landroid include $(BUILD_STATIC_LIBRARY)
在Eclipse中配置NDK, Eclipse->Window->Prefreneces->Android->NDK.
三、如果直接编译的话会提示如下错误
fatal error: EGL/egl.h: No such file or directory
查看EGL的支持是在2.3版本以上，所以我们需要添加平台的支持，所以在jni目录修改下Application.mk文件来指定编译平台：
# Uncomment this if you‘re using STL in your project # See CPLUSPLUS-SUPPORT.html in the NDK documentation for more information # APP_STL := stlport_static APP_ABI := armeabi armeabi-v7a x86 APP_PLATFORM := android-9
四、在Eclipse中执行Ctrl+B，就会编译出libSDL2.so，编译过程如下:

后面我们就可以来使用sdl进行开发了
