ndk-build:静态链接到libxml.a时对..错误的未定义引用

Question

当我使用ndk-build工具编译单个c ++源文件时,我得到了很多未定义的引用...错误.为了记录,我在linux主机系统上使用NDK r6.

首先,我一整天都在反对这个问题,所以如果我要留下一些东西或者解释自己有点快,我很抱歉.请向我询问任何其他信息.

我的源代码有很多我想要静态链接到的依赖库.我在Android.mk文件中定义了所有不同的依赖库,如下所示:

include $(CLEAR_VARS)

LOCAL_MODULE    := <name>
LOCAL_SRC_FILES := lib<name>.a
LOCAL_EXPORT_C_INCLUDES := <header files related to this lib>

include $(PREBUILT_STATIC_LIBRARY)

虽然我确保使用我的Android.mk和Application.mk文件在我的jni /文件夹中以lib.a的形式提供这些文件.(和我的源文件)另外我通过添加APP_STL := stlport_static到我的Application.mk文件添加了STL支持.我的单个源文件(riidr-jni.cpp)目前是:

#include <string>
#include <jni.h>
#include <android/log.h>
#include "../com_riidr_apps_reader_RiidrEbookReaderActivity.h"
#include <dp_all.h>

void Java_com_riidr_apps_reader_RiidrEbookReaderActivity_init ( JNIEnv* env, jobject thiz ) {
    __android_log_write(ANDROID_LOG_INFO, "Riidr", "JNI init - start");
    dp::platformInit( dp::PI_DEFAULT );
}

如果我取消注释该dp::platformInit( dp::PI_DEFAULT );行并将其替换为std::string test = "asd";我没有任何错误,这使我相信因此STL lib被正确导入和链接.

我的Android.mk文件的最后一条指令是这样的

include $(CLEAR_VARS)

LOCAL_MODULE    := riidr-jni
LOCAL_SRC_FILES := riidr-jni.cpp
LOCAL_LDLIBS := -llog -ldl -lz
LOCAL_STATIC_LIBRARIES :=  \
hobbes \

include $(BUILD_SHARED_LIBRARY)

运行ndk-build工具时出现的错误如下:

任何信息,问题或任何事实都非常感谢.

Answer 1

添加行

LOCAL_ALLOW_UNDEFINED_SYMBOLS := true

到Android.mk文件,它应该工作.正如在ndk doc中所解释的那样,这是因为ndk执行调试检查,即使是为了避免运行时链接错误,并且对于某些动机,它在预构建的库中找不到正确的引用.希望它可以提供帮助.

Answer 2

您必须添加APP_STL := stlport_static到Application.mk文件，而不是Android.mk.

编辑：据我所知，您还没有链接到 stlport 静态库。所以我认为你应该添加类似的-lstlport内容LOCAL_LDLIBS。
