当我启动程序并按下pushButton2时，它会显示logindialog。当我输入内容并按下logindialog的按钮时，程序即将消失。如果我在.pro文件中注释cryptopp行，程序就能正常工作。如果我留空lineEdit并按下logindialog的passwordButton，它再次询问我密码，我给空白，但再次死 - 看到第二个日志出现（注意两个日志中的P1，P2，P3 ......）。我从this链接和来自this的criptopp获取了openssl。我认为这个问题出现在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，并且已经阅读了关于＆＃34;堆栈跟踪调整的内容＆＃34;但不知道该怎么做。没关系，在这种情况下会出现什么问题？

版本之后：

我在我的Android 4.1.2设备LG optimus L1 e410上测试过它。无论我是用Android 23/14/18/16在AVD上测试它 - >它失败了。如果cryptopp被评论，一切顺利。 log2编译输出与第一个相同，只是时间不同。

第2版之后：

pushButton的cryptopp使用的应用程序日志：

请参阅mainwindow.cpp中的pushButton并在mainwindow.h中注释thigs（它们实际上没有被注释）。

您手动加载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（在我的情况下为libgnustl_shared.so，您可以在编译后在android-build \ libs \ armeabi-v7a文件夹中检查）。如果您的加密库使用不同的加密库（显然是libstlport_shared.so），那么从.pro文件手动加载它（ANDROID_EXTRA_LIBS +=，LIB +=）将使libcryptopp.so可加载，但是每当你将STL对象（例如std::string）从你的代码传递给加密函数时，你很可能会遇到段错误。

两个环境（您的代码和加密一个）没有使用相同的STL实现，因此他们无法安全地发送任何STL对象而没有严重的潜在分段错误（因为人们会认为对象是从其自己的实现创建的它实际上是用另一个创建的：对象很可能具有不同的属性....就像在两个完全不同的类型之间强制转换一样。）

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，但我很确定你会看到“将std :: string传递给CryptoPP :: StringSink”而不是“创建HexEncoder”。

您应该重新编译libcryptopp.so以使其使用与主程序相同的STL实现（并指出lib将与该STL实现一起使用）。
