连接故障使用Android NDK R5B静态库

问题描述

最近升级到NDK R5B，并构建失败，未定义的引用到位于静态库函数。

下面是误差

<$p$p><$c$c>/home/brian/workspace/VoiceEngineDemo/obj/local/armeabi-v7a/objs-debug/voiceenginejni/voice_engine_jni.o:在功能上`initVE：
/home/brian/workspace/VoiceEngineDemo/jni/voice_engine_jni.c:944：未定义的引用`VE_ADT_create

这似乎链接过程没有加载，即使它是在Android.mk定义的静态模块如下：

  LOCAL_PATH：= $（叫我-DIR）包括$（CLEAR_VARS）LOCAL_MODULE：= voiceenginejniLOCAL_SRC_FILES：= voice_engine_jni.c printing.c jaudio.c etime.cLOCAL_CFLAGS：= -D __arm -D ANDROID -D USE_AEC_DEFAULTS -D USE_EC_DEFAULTS -D _DEBUG -D EC_VARIANT = EC_VARIANT_NEC -D AECG1_5_ENABLELOCAL_STATIC_LIBRARIES：= libvoiceengine libcpufeatures libaecg2LOCAL_LDLIBS：= -llog -ldl包括$（BUILD_SHARED_LIBRARY）$（呼叫进口模块，cpufeatures）
 

该VE_ADT_create函数位于libvoiceengine.a，已被放在/ OBJ /本地/ armeabi-V7A /目录。

我倒是AP preciate它，如果任何人都可以在此提供一些线索给我。谢谢！

解决方案

好像每个库需要将自己的prebuilt模块，如图：的

Recently upgraded to NDK r5b, and the build fails with "undefined reference" to functions located in a static library.

Here is the error

/home/brian/workspace/VoiceEngineDemo/obj/local/armeabi-v7a/objs-debug/voiceenginejni/voice_engine_jni.o: In function `initVE':
/home/brian/workspace/VoiceEngineDemo/jni/voice_engine_jni.c:944: undefined reference to `VE_ADT_create'

It seem the link process is not loading the static module even though it is defined in the Android.mk as follows:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE               := voiceenginejni

LOCAL_SRC_FILES            := voice_engine_jni.c printing.c jaudio.c etime.c

LOCAL_CFLAGS               := -D __arm  -D ANDROID -D USE_AEC_DEFAULTS -D USE_EC_DEFAULTS -D _DEBUG -D EC_VARIANT=EC_VARIANT_NEC -D AECG1_5_ENABLE

LOCAL_STATIC_LIBRARIES     := libvoiceengine libcpufeatures libaecg2

LOCAL_LDLIBS               := -llog -ldl

include $(BUILD_SHARED_LIBRARY)

$(call import-module,cpufeatures)

The VE_ADT_create function is located in libvoiceengine.a, which has been placed in the /obj/local/armeabi-v7a/ directory.

I'd appreciate it if anyone can shed some light on this for me. Thanks!

解决方案

Seems each library needs to be its own prebuilt module as shown in: Linking thirdparty libs (libs.a) with NDK
