UnsatisfiedLinkError:找不到libcrypto.so.1.0.0

标签: android-ndk openssl

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.solibsslNative.so个文件,但是我收到有关libcrypto.so.1.0.0未找到错误的错误。我该如何解决这个问题?

这是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);
    }

}

我有类似的问题。 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readelf来查看分配给库的实际名称的一个很好的技巧(如果您的.so文件是elf格式,如果没有,请参阅this发布其他选项)。 / p>

运行此功能后,您需要查找DEPEND& 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,你基本上有两个选择 - 重新编译你的libcrypto.so& libssl.so再次,这次添加适当的标志,以防止它附加版本后缀,或编辑库以删除版本后缀。我将展示如何做第二个选项。

确保安装了rpl命令行工具。如果不是,请运行:

brew install rpl

您可能需要使用sudo运行此功能。

安装此工具后,您需要使用它来编辑ssl和amp;中的符号。像这样的加密库:

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

差不多完成了!

再次运行readelf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,加载库时,请务必使用调整后的文件名:

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

现在应该有用了。希望这能解决你的问题。
