春山眉黛~xvid.mk文件书写注意事项

一、
vendor/sprd/proprietories-source/sprd_codecs/xvid//src/portab.h:134:6: error: You are trying to compile Xvid without defining address bus size.
#    error You are trying to compile Xvid without defining address bus size.
     ^
vendor/sprd/proprietories-source/sprd_codecs/xvid//src/portab.h:372:10: error: You are trying to compile Xvid without defining the architecture type.
#        error You are trying to compile Xvid without defining the architecture type.
         ^
solution：add ---LOCAL_CFLAGS += -DARCH_IS_32BIT -DARCH_IS_GENERIC -Wno-int-to-pointer-cast -Wno-implicit-function-declaration --std=c99 
          to .mk document
reason:portab.h 配置信息不完善ARCH_IS_32BIT、ARCH_IS_GENERIC，需要将这些信息写入.mk文件中


二、
vendor/sprd/proprietories-source/sprd_codecs/xvid/examples/xvid_encraw.c:57:10: fatal error: 'xvid.h' file not found
#include "xvid.h"


solution :将.mk文件重新命名，放在了统一的路径下面，在整体的Android.mk文件中加入include $(LOCAL_PATH)/xvid.mk、include $(LOCAL_PATH)/xvid_encraw.mk
重新写.mk文件中头文件和源文件的路径
XVID_PATH := xvid/
...
LOCAL_SRC_FILES := \
$(XVID_PATH)/examples/xvid_encraw.c \

LOCAL_C_INCLUDES := \
$(LOCAL_PATH)/$(XVID_PATH)/src \
编译通过


三、

书写一个.mk文件需要修改的地方

xvid_encraw.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
XVID_PATH := xvid/  //方便写路径
LOCAL_MODULE := utest_sw_xvidenc //生成文件的名称
LOCAL_MODULE_TAGS := debug


LOCAL_CFLAGS := -fno-strict-aliasing -Wno-date-time -D_VSP_LINUX_ -D_VSP_
LOCAL_CFLAGS += -DARCH_IS_32BIT -DARCH_IS_GENERIC -Wno-int-to-pointer-cast -Wno-implicit-function-declaration --std=c99 //文件需要进行的配置信息，要包含的define信息


LOCAL_PRELINK_MODULE := false
LOCAL_ARM_MODE := arm


LOCAL_SRC_FILES := \
$(XVID_PATH)/examples/xvid_encraw.c \  //源文件路径和文件名称

LOCAL_C_INCLUDES := \
$(LOCAL_PATH)/$(XVID_PATH)/src \  //头文件路径


LOCAL_SHARED_LIBRARIES :=  libomx_xvid_sw  //编译这个源文件需要调用的库的名称


LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES)
LOCAL_PROPRIETARY_MODULE := true


include $(BUILD_EXECUTABLE)

Android.mk

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)


ifeq ($(strip $(TARGET_VSP_PLATFORM)),whale)
include $(LOCAL_PATH)/h265dec_hw.mk
include $(LOCAL_PATH)/h265enc_hw.mk
include $(LOCAL_PATH)/vspenc_hw.mk
endif


ifeq ($(strip $(TARGET_VSP_PLATFORM)),iwhale2)
include $(LOCAL_PATH)/h265dec_hw.mk
include $(LOCAL_PATH)/h265enc_hw.mk
include $(LOCAL_PATH)/vp9dec_hw.mk
include $(LOCAL_PATH)/vp9enc_hw.mk
endif




include $(LOCAL_PATH)/h264dec_hw.mk
include $(LOCAL_PATH)/h264dec_sw.mk
include $(LOCAL_PATH)/h264enc_hw.mk
include $(LOCAL_PATH)/m4vh263dec_hw.mk
include $(LOCAL_PATH)/m4vh263dec_sw.mk
include $(LOCAL_PATH)/m4vh263enc_hw.mk
include $(LOCAL_PATH)/vpxdec_hw.mk
include $(LOCAL_PATH)/m4vh263enc_sw.mk
include $(LOCAL_PATH)/xvid.mk
include $(LOCAL_PATH)/xvid_encraw.mk
 //添加这两个文件，编译的过程中就会调用这两个新写好的mk文件来处理。

include $(call all-makefiles-under,$(LOCAL_PATH))

四、编译过程中遇见的类型检查报错问题处理

更改编译的环境，le不能通过，原因暂时不明~
