本文详细介绍了如何针对s3c6410平台修改Webrtc库源码以解决编译错误，并通过调整核心构建文件优化了构建流程，确保了Webrtc库在目标平台上的正确编译和部署。

1、修改源码使其支持s3c6410：

修改/WORKING_DIRECTORY/build/target/board/generic下的BoardConfig.mk文件：

修改以下内容为：
TARGET_ARCH_VARIANT := armv5te-vfp
TARGET_CPU_ABI := armeabi
TARGET_CPU_ABI2 := armeabi

修改external/webrtc/src/common_audio/signal_processing_library/main/interface/spl_inl.h，如图：

否则会报错

/tmp/ccqlae8X.s: Assembler messages:
/tmp/ccqlae8X.s:208: Error: selected processor does not support `qadd16 ip,r0,r3'
/tmp/ccqlae8X.s:236: Error: selected processor does not support `qadd16 r9,r4,r9'
/tmp/ccqlae8X.s:253: Error: selected processor does not support `qadd16 ip,ip,r4'
make: *** [out/target/product/OK6410/obj/STATIC_LIBRARIES/libwebrtc_spl_intermed
iates/auto_corr_to_refl_coef.o] Error 1

2、修改/WORKING_DIRECTORY/build/core/main.mk

include $(BUILD_SYSTEM)/legacy_prebuilts.mk
ifneq ($(filter-out $(GRANDFATHERED_ALL_PREBUILT),$(strip $(notdir $(ALL_PREBUILT)))),)
$(warning *** Some files have been added to ALL_PREBUILT.)
$(warning *)
$(warning * ALL_PREBUILT is a deprecated mechanism that)
$(warning * should not be used for new files.)
$(warning * As an alternative, use PRODUCT_COPY_FILES in)
$(warning * the appropriate product definition.)
$(warning * build/target/product/core.mk is the product)
$(warning * definition used in all products.)
$(warning *)
$(foreach bad_prebuilt,$(filter-out $(GRANDFATHERED_ALL_PREBUILT),$(strip $(notdir $(ALL_PREBUILT)))),$(warning * unexpected $(bad_prebuilt) in ALL_PREBUILT))
$(warning *)
$(warning ALL_PREBUILT contains unexpected files) //把error改为warning
endif

修改/WORKING_DIRECTORY/build/core/product.mk

define assert-product-vars
$(strip \
$(eval changed_variables:=)
$(foreach v,$(_product_stash_var_list), \
    $(if $(call streq,$($(v)),$($(strip $(1))_$(call rot13,$(v)))),, \
        $(eval $(warning $(v) has been modified: $($(v)))) \
        $(eval $(warning previous value: $($(strip $(1))_$(call rot13,$(v))))) \
        $(eval changed_variables := $(changed_variables) $(v))) \
   ) \
$(if $(changed_variables),\
    $(eval $(warning The following variables have been changed: $(changed_variables))),) //把error改为warning
)

修改/WORKING_DIRECTORY/build/core/Makefile

define check-product-copy-files
$(if $(filter %.apk, $(1)),$(warning \ //把error改为warning
Prebuilt apk found in PRODUCT_COPY_FILES: $(1), use BUILD_PREBUILT instead!))
