全志Linux Tina编译demoOmxVdec错误

测试裸流

Making install in demoOmxVdec
make[6]: Entering directory '/home/liuxueneng/WorkCode/Homlet-Tina-H2_H3/out/dolphin-p1/compile_dir/target/libcedarx/libcedarx/demo/demoOmxVdec'

编译的文件位于

.libcedarx/libcedarx/demo/demoOmxVdec

查找头文件位置

$find ./ -name "OMX_Types.h"
./libcedarc/openmax/include/OMX_Types.h
$ls ./libcedarc/openmax/include/
OMX_Audio.h      OMX_ContentPipe.h  OMX_Image.h     OMX_Index.h     OMX_Other.h  OMX_VideoExt.h
OMX_Component.h  OMX_Core.h         OMX_IndexExt.h  OMX_IVCommon.h  OMX_Types.h  OMX_Video.h

现在需要omx这个头文件到路径包含到对应的Makefile里面，

 349 demoOmxVdec_CFLAGS = $(CFLAGS_CDXG) $(LOCAL_INCLUDE)
 350 demoOmxVdec_CPPFLAGS = $(CPPFLAGS_CDXG) $(LOCAL_INCLUDE)
 351 LOCAL_INCLUDE = -I$(top_srcdir) \
 352                 -I$(top_srcdir)/libcore/base/include \
 353                 -I$(top_srcdir)/libcore/stream/include \
 354                 -I$(top_srcdir)/libcore/parser/include \
 355                 -I$(top_srcdir)/libcore/common/iniparser \
 356                 -I$(top_srcdir)/libcore/playback/include/ \
 357                 -I$(top_srcdir)/external/include/adecoder \
 358                 -I$(top_srcdir)/external/include \
 359                 -I$(top_srcdir)/../libcedarc/include \
 360                 -I$(top_srcdir)/../libcedarc/openmax/omxcore/inc/ 

查看Makefile发现LOCAL_INCLUDE原本是想包含该头文件路径，但是却被写错了“

-I$(top_srcdir)/../libcedarc/openmax/omxcore/inc/ 

正确的应该是

-I$(top_srcdir)/../libcedarc/openmax/include/

Makefile是由Makefile.am-->Makefile.in自动生成，正常需要修改Makefile.am文件然后重新configure生成新的Makefile执行Make
但在这里修改比较小，而且我只需要重新编译出结果即可，所以直接修改Makefile修正头文件路径即可。

另外在demo目录下的Makefile.am中有针对

demoOmxVdec demoOmxVenc

编译屏蔽的注释，具体原因不详。。。

   1 if XPLAYERDEMO_ENABLE
   2 SUBDIRS = xplayerdemo demoOmxVdec parserdemo
   3 endif
   4
   5 #SUBDIRS = muxtest parserdemo demoVdecoder demoVencoder xmetademo \
   6 #          jpegdemo recoderdemo xplayerdemo
   7 #not enable omx in linux default
   8 #demoOmxVdec demoOmxVenc   

demoOmxVdec parserdemo 是我自己加进去编译的。
