UnsatisfiedLinkError:找不到libcrypto.so.1.0.0

Question

我在eclipse中使用android ndk.我编译了我的项目,但在运行时遇到了错误.我有libcrytpoNative.so和libsslNative.so文件但我得到这个错误libcrypto.so.1.0.0没有找到错误.我该怎么解决这个问题？

这是输出 ndk-build V=1

这是加载libs的MainActivity.java:

package com.example.myproject;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

public class MainActivity extends Activity {

    static {
        System.loadLibrary("gmp");             
//        System.loadLibrary("ssl");
//        System.loadLibrary("crypto");
        System.loadLibrary("glib");
        System.loadLibrary("pbc"); 
        System.loadLibrary("sslNative");
        System.loadLibrary("cryptoNative");
        System.loadLibrary("cpabe");          
    }

    //System.loadLibrary("ssl_static");


    public static native void InitMainActivityjni();
    public native String cpabeNative();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        TextView  tv = new TextView(this);
        tv.setText(cpabeNative());
        setContentView(tv);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

}

谢谢

我遇到了类似的问题.Android不喜欢版本化的库文件,在这种情况下,单独更改.so lib的文件名是不行的.您可以通过运行来查看分配给库的实际名称的一个很好的技巧readelf(如果您的.so文件是精灵格式,如果没有,请参阅此帖子了解其他选项).

运行此功能后,您需要查找DEPEND&下显示的项目SONAME.如果你看到版本化的.so.1.0.0名称,那么继续阅读,救恩就在附近:)

现在,您基本上有两个选择 - 重新编译libcrypto.so和libssl.so,这次添加适当的标志以防止它附加版本后缀,或者编辑lib以删除版本后缀.我将展示如何做第二个选项.

确保已rpl安装命令行工具.如果不是,请运行:

brew install rpl

你可能需要运行它sudo.

安装此工具后,您将需要使用它来编辑ssl和crypto库中的符号,如下所示:

rpl -R -e .so.1.0.0 "_1_0_0.so" /path/to/libssl.so
rpl -R -e .so.1.0.0 "_1_0_0.so" /path/to/libcrypto.so

几乎完成了!

readelf再次运行该工具以确保符号已正确更改.现在唯一要做的就是将实际文件名更改为libssl_1_0_0.so&libcrypto_1_0_0.so,并在加载库时,确保使用调整后的文件名:

System.loadLibrary("ssl_1_0_0");
System.loadLibrary("crypto_1_0_0");

事情现在应该奏效.希望这能解决你的问题.
