Question

试图解决这个问题几个小时。我的Qt程序依赖于https连接但无法在Arch上启动它（在Debian和Ubuntu上运行正常）。

我将/ usr / lib添加到LD_LIBRARY_PATH lrwxrwxrwx 1 root root 13 2. lis 17.20 /usr/lib/libssl.so -> libssl.so.1.1 -r-xr-xr-x 1 root root 502024 25. kvě 18.54 /usr/lib/libssl.so.1.0.0 -rwxr-xr-x 1 root root 434176 2. lis 17.21 /usr/lib/libssl.so.1.1 -rwxr-xr-x 1 root root 359736 5. říj 22.49 /usr/lib/libssl3.so

节目输出

lrwxrwxrwx 1 root root      16  2. lis 17.20 /usr/lib/libcrypto.so -> libcrypto.so.1.1
-r-xr-xr-x 1 root root 2842880 25. kvě 18.54 /usr/lib/libcrypto.so.1.0.0
-rwxr-xr-x 1 root root 2594952  2. lis 17.21 /usr/lib/libcrypto.so.1.1

ls / usr / lib / libssl *

int main(int argc, char *argv[]) {
    QApplication a(argc, argv);
    qDebug()<<"SSL version use for build: "<<QSslSocket::sslLibraryBuildVersionString();
    qDebug()<<"SSL version use for run-time: "<<QSslSocket::sslLibraryVersionNumber();
    qDebug()<<QCoreApplication::libraryPaths();

    return 0;
}

ls -l / usr / lib / libcrypto *

Answer 1

我需要重新安装我的Ubuntu并安装openssl 1.0.x版本而不是1.1.x版本。除此之外，如果需要，您可以在构建项目之前运行Pixel。

Answer 2

我在使用Qt 5.10.1的ubuntu 16.04上遇到了同样的问题。我刚刚在我的机器上编译了Qt并安装了它，并且修复了ssl问题并开始使用opnessl 1.1.0。我已经配置了没有-openssl-linked标志的Qt。考虑到编译可能需要相当长的时间，2-4小时

Answer 3

将Ubuntu 16.x升级到18.04后，我遇到了同样的问题。原因似乎是新的Ubuntu上的默认libssl版本是1.1.0，而Qt的预构建二进制文件到现在为止期望是1.0.0（有关此问题的更多详细信息，请参见https://bugreports.qt.io/browse/QTBUG-68156）。

我的解决方法如下。

创建指向libssl 1.0.0版的符号链接

ln -s /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 libssl.so

确保您的LD_LIBRARY_PATH包含1）中的目录。

现在启动您的Qt可执行文件将选择正确的libssl版本。

Qt即使安装了libssl也找不到
