编译 Android 版本的 libmad

1、 下载libmad源码2、 在目录C:\cygwin\home\Administrator\Android-ndk-r4b-windows\android-ndk-r4b\samples\下创建目录jni,并把libmad的源码解压到该目录下,这样mad.h的目录是:C:\cygwin\home\Administ......

1、 下载libmad源码

 

2、 在目录C:\cygwin\home\Administrator\Android-ndk-r4b-windows\android-ndk-r4b\samples\下创建目录jni,并把libmad的源码解压到该目录下,这样mad.h的目录是:C:\cygwin\home\Administrator\android-ndk-r4b-windows\android-ndk-r4b\samples\libmad\jni\libmad-0.15.1b

 

3、 在jni目录下建立Android.mk内容:

 

include$(all-subdir-makefiles)

 

4、 在jni/libmad-0.15.1b目录下建立Android.mk,内容:

 

LOCAL_PATH := $(call my-dir)

 

include $(CLEAR_VARS)

 

LOCAL_MODULE := mad

 

LOCAL_ARM_MODE := arm

 

LOCAL_SRC_FILES := bit.c decoder.c fixed.c frame.c huffman.c layer12.clayer3.c stream.c synth.c timer.c version.c

 

LOCAL_CFLAGS := -DHAVE_CONFIG_H -DFPM_ARM -ffast-math -O3

 

include $(BUILD_SHARED_LIBRARY)

 

5、 启动Cygwin,到目录samples下

 

6、 执行:../ndk-build NDK_PROJECT_PATH=$NDK_ROOT/samples/libmad

 

注意:这里使用的config.h不是执行configure生成的,而是从网上down的一个,内容是:
