推荐:【android NDK及JNI】ubuntu12.10 64位 + android-ndk-r9 编译ffmpeg遇到的问题 .

android-ndk-r8d/build/core/build-binary.mk:41:?***?target?file? `clean'?has?both?:?and?::?entries.??Stop. ? ? 我也遇到了相同的问题,不过经过一步步排查

android-ndk-r8d/build/core/build-binary.mk:41: *** target file 

`clean' has both : and :: entries.  Stop.     我也遇到了相同的问题,不过经过一步步排查,是因为在libavfilter目录中的Makefile的末尾处多了 Clean 这个玩意儿 将其注释掉或者删掉就可以了     恢复改方法 /libavutil/libm.h:183:40: error: static declaration of 'truncf' follows non-static declaration
  libm.h的static方法删除掉   /*#define av_restrict restrict*/
#define restrict      file included from jni/ffmpeg/libavcodec/aacdec.c:82:0:
jni/ffmpeg/libavcodec/../libavutil/float_dsp.h:150:50: error: expected ';', ',' or ')' before 'v1'
jni/ffmpeg/libavcodec/aacdec.c: In function 'apply_mid_side_stereo':
jni/ffmpeg/libavcodec/aacdec.c:1746:29: error: 'AVFloatDSPContext' has no member named 'butterflies_float'
make: *** [obj/local/armeabi/objs/avcodec/aacdec.o] Error 1     c、修改jni/ffmpeg/config.h下的 
#define avrestrict restrict为#define restrict

这个应该改为 #define av_restrict     stdlib 的错误  /home/usr/android-ndk-r9/platforms/android-18/arch-arm/usr/include/stdlib.h:54:14: error: expected identifier or '(' before 'void'
/home/usr/android-ndk-r9/platforms/android-18/arch-arm/usr/include/stdlib.h:54:14: error: expected ')' before numeric constant   --extra-cflags="-I${NDK_ROOT}/platforms/${PLATFORM}/arch-arm/usr/include -fPIC -DANDROID -std=c99" \ 添加了I,应该是stdlib的头文件没有找对导致的      


jni/ffmpeg/libavutil/parseutils.c:541:15: error: storage size of 'dt' isn't known
jni/ffmpeg/libavutil/parseutils.c:634:20: error: variable 'dt2' has initializer but incomplete type
jni/ffmpeg/libavutil/parseutils.c:634:38: error: invalid type argument of unary '*' (have 'int')

jni/ffmpeg/libavutil/parseutils.c:634:23: error: storage size of 'dt2' isn't known

这个问题的解决方法是:打开 libavutil/parseutils.h,把 #include <time.h> 替换为 #include <sys/../time.h>     undefined reference to 'inflateReset' 在libAvcodec的mk文件里做修改、 参考 http://blog.sina.com.cn/s/blog_5c4dd3330100mpdx.html   LOCAL_PATH := $(call my-dir)

移植ffmpeg的时候如果遇到这样的情况,在两个文件的Makefile中删掉一个log2_tab.o文件就可以了
打开libavformat的Makefile文件          lfg.o                                                            \

       mem.o                                                            \                                                   \   删除文件,如果是多行,就不要用注释了,直接删除掉     修改libavcodec的Makefile OBJS-$(CONFIG_RDFT)                    += rdft.o $(RDFT-OBJS-yes)
OBJS-$(CONFIG_SHARED)                  += log2_tab.o
OBJS-$(CONFIG_SINEWIN)                 += sinewin.o   ------------------------------------------   -------------------------------------------
