在android ndk项目中找不到libxml2

每个人都好。我尝试将libxml2添加到我的android ndk项目时，已经浪费了将近一周的时间来解决出了什么问题。

所以即使我将xml2.so作为共享库添加到我的项目中 - 没有任何反应。它strill找不到libs并给了我很多这个

start-spice中的

代码头看起来像这样：

#include <jni.h>
#include <android/log.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <libxml/parser.h>
#include <netdb.h>
#include <unistd.h>
#include <errno.h>
#include <libxml/parser.h>
#include <libxml/tree.h>

我在java代码中添加：

 static
    {
       System.loadLibrary("start-spice");
    }

如果有人帮忙，真的很感激！

答案 0 :(得分：2)

如果您在$(LOCAL_PATH)/libxml2/libxml2.a中拥有适用于Android的预建静态库，则可以在 spice-android 项目中使用它，

LOCAL_STATIC_LIBRARIES += xml2

使用

而不是 xml2 的include $(BUILD_SHARED_LIBRARY) 
LOCAL_SRC_FILES :=  libxml2/libxml2.a
include $(PREBUILT_STATIC_LIBRARY)

如果您有充分的理由将 xml2 用作单独的共享库，则需要添加调用

System.loadLibrary("xml2");

到您的Java代码（在加载libspice-android.so之前）并用{/ 1>替换LOCAL_SRC_FILES := $(LOCAL_PATH)/libxml2/libxml2.a 

LOCAL_WHOLE_STATIC_LIBRARIES :=  $(LOCAL_PATH)/libxml2/libxml2.a

答案 1 :(得分：1)

这是链接共享库的问题，您需要在LOCAL_LDLIBS += $(LIB_PATH) -lxm2之前添加LOCAL_SHARED_LIBRARIES= xml2。
