当我启动程序并按下 pushButton2 时，会出现登录对话框。当我在其中输入内容并按下登录对话框的按钮时，程序就死了。如果我在 .pro 文件中评论 cryptopp 行，程序将正常运行。如果我将 lineEdit 留空并按下 logindialog 的 passwordButton，它会再次询问我有关密码的信息，我给出空白，但又死了 - 看到第二个日志出现(注意两个日志中的 P1、P2、P3...)。我从 this 中获取了 openssl链接和 criptopp 来自 this .我认为问题出在 cryptopp 的某个地方。如何增加 qt android 的堆栈和堆大小？我不认为这是问题所在，并且已经阅读了一些有关“堆栈跟踪调试”的内容，但不知道该怎么做。没关系，在这种情况下可能是什么问题？

修改后:

我已经在我的 android 4.1.2 设备 LG optimus L1 e410 上对其进行了测试。无论我是否使用 android 23/14/18/16 在 AVD 上测试它 -> 它都失败了。如果 cryptopp 被评论一切正常。 log2编译输出与第一个相同，只是时间不同。

第 2 版之后:

pushButton 使用 cryptopp 的应用程序日志:

I/Adreno200-EGL( 6066): Reconstruct Branch: NOTHING
W/IInputConnectionWrapper( 6066): showStatusIcon on inactive InputConnection
F/libc    ( 6066): Fatal signal 11 (SIGSEGV) at 0x54ff002e (code=1), thread 6156 (le.testAndroid4)
I/DEBUG   (  147): pid: 6066, tid: 6156, name: le.testAndroid4  >>> org.qtproject.example.testAndroid4 <<<
I/ActivityManager(  457): Process org.qtproject.example.testAndroid4 (pid 6066) has died.


"org.qtproject.example.testAndroid4" died.

请参阅 mainwindow.cpp 中的 pushButton 和 mainwindow.h 中的注释内容(它们实际上没有注释)。

最佳答案

您正在手动加载 libSTLport_shared.so，我想这是因为 libcryptopp.so 需要它。

默认情况下，Qt 在编译和部署时使用 STL 库(在我的例子中为 libgnuSTL_shared.so，您可以在编译后在 android-build\libs\armeabi-v7a 文件夹中检查它)。如果您的加密库使用不同的库(显然是 libSTLport_shared.so)，请像您一样从 .pro 文件手动加载它(ANDROID_EXTRA_LIBS += , LIB + =) 将使 libcryptopp.so 可加载，但是每当您传递 STL 对象 (std::string 例如)从您的代码到加密函数。

两个环境(您的代码和加密环境)没有使用相同的 STL 实现，因此它们无法安全地相互发送任何 STL 对象而不会出现严重的潜在段错误(因为当它实际上是用另一个创建的:对象很可能具有不同的属性....这就像在两种完全不同的类型之间强制转换)。

你可以这样验证:

void MainWindow::on_pushButton_clicked()
{
    byte ivec[16];
    byte salt[32];

    qDebug() << "Calling OS_GenerateRandomBlock";
    CryptoPP::OS_GenerateRandomBlock(false, salt, sizeof(salt));
    qDebug() << "Calling OS_GenerateRandomBlock";
    CryptoPP::OS_GenerateRandomBlock(false, ivec, sizeof(ivec));

    std::string v;

    qDebug() << "Passing std::string to CryptoPP::StringSink";    
    CryptoPP::StringSink* sink = new CryptoPP::StringSink(v);

    qDebug() << "Creating HexEncoder";    
    CryptoPP::HexEncoder hex( sink );

    hex.Put(salt, sizeof(salt));
    hex.MessageEnd();

    QMessageBox::about(this,tr("Test1"),tr(v.c_str()));
    QMessageBox::about(this,tr("Test1"),tr("XXX"));
}

请确认，但我很确定您会看到“将 std::string 传递给 CryptoPP::StringSink”而不是“创建 HexEncoder”。

您应该重新编译 libcryptopp.so 以使其使用与您的主程序相同的 STL 实现(并且希望该库能够与该 STL 实现一起工作)。
