Ubuntu上的Qt和OpenSSL不兼容版本

我在尝试使QNetwork类与Ubuntu 18.04上的Qt5.11.1配合使用时遇到问题

我的系统上安装了openssl 1.1.0g和libssl-dev。

Qt使用的openssl版本是1.0.2k。我已经与QSslSocket::sslLibraryBuildVersionString()进行了核对。加QSslSocket::supportsSsl()返回false。

我正在努力解决这个问题，但是我总是遇到这些错误：

qt.network.ssl: QSslSocket: cannot resolve CRYPTO_num_locks
qt.network.ssl: QSslSocket: cannot resolve CRYPTO_set_id_callback
qt.network.ssl: QSslSocket: cannot resolve CRYPTO_set_locking_callback

qt.network.ssl: Incompatible version of OpenSSL

我已经检查了多个与此有关的问题和论坛，但似乎对我没有任何帮助。有人知道吗？

我终于设法使它起作用。

我已经从源代码安装了openssl 1.0.2k。我已经下载了需要的版本here，并按照this page上的教程进行操作。

这样做之后，我仍然遇到一些错误，但对于不兼容的版本却没有。要修复我已经安装的libssl1.0-dev，一切都很好（谢谢this guy）。

我希望这会对某人有所帮助。

我已将<?php foreach($tickerDisplays as $key => $ticker):?> <form id="Items" method="post"> <label id="ItemLabel">Item 1: </label> <input type="text" name="Items[]"><br/> <!--form starts with one input--> <button type="button" class="moreItems_add">+</button> <!--button dynamically adds input, up to 10 per form--> <input type="hidden" name="tickerID" id="tickerID" class="tickerIdClass" value="<?php echo $ticker['ticker'] ?>"><!--hidden input used for tickerID--> <input type="submit" name="saveTickerItems" value="Save Ticker Items"> <!--submit button--> </form> <?php endforeach;?> <!-- This is the functionality for each form to click the '+' button and create new inputs --> <script type="text/javascript"> $("button.moreItems_add").on("click", function(e) { var tickerID = $(this).closest('form').find('.tickerIdClass').val(); //get value of hidden input for form var numItems = $("input[type='text']", $(this).closest("form")).length; if (numItems < 10) { var html = '<label class="ItemLabel">Item ' + (numItems + 1) + ': </label>'; html += '<input type="text" name="Items[]"/><br/>'; $(this).before(html); console.log(tickerID); } }); </script> <!-- This is the ajax call to send all filled out and created inputs from form along with the hidden input --> <script type="text/javascript"> $("#Items").submit(function(e) { e.preventDefault(); var data = $("#Items").serializeArray(); console.log(data); $.ajax({ type: "POST", url: "addticker.php", data: $("#Items").serializeArray(), // serializes the form's elements. success: function(data) { alert(data); // show response from the php script. } }); }); </script> 和libcrypto.so（v1.0.2）复制到当前的编译器lib目录（libssl.so）中。 在我的情况下，我在<QTDIR>/5.11.1/gcc_64/lib中使用了theese 2个库：/usr/lib/x86_64-linux-gnu/和libssl.so.1.0.0，并进行了复制和重命名。 它对我有用。

我通过以下方式解决了创建opensl 1.1.0链接的问题：

  1. 在/ opt / f5 / vpn / lib中删除libcrypto.so.1.0.0和libssl.so.1.0.0;

  2. 创建链接：

    sudo ln -s /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1 /opt/f5/vpn/lib/libcrypto.so.1.0.0 

sudo ln -s /usr/lib/x86_64-linux-gnu/libssl.so.1.1 /opt/f5/vpn/lib/libssl.so.1.0.0

我在Ubuntu 16.04上使用Qt 5.13.1遇到了这个问题。

在我的Qt环境中，QSslSocket::sslLibraryBuildVersionString()和QSslSocket::supportsSsl()的值为"OpenSSL 1.1.1b 26 Feb 2019"和false。

每次QNetworkAccessManager访问https地址时都会生成此输出：

以上所有解决方案都不适合我。我在Ubuntu上安装了Homebrew软件包管理器，然后像这样安装了openssl@1.1：

$ brew install openssl@1.1

然后我将这些行添加到我的项目文件中：

LIBS += -L/home/linuxbrew/.linuxbrew/Cellar/openssl@1.1/1.1.1c/lib -lssl -lcrypto
INCLUDEPATH += /home/linuxbrew/.linuxbrew/Cellar/openssl@1.1/1.1.1c/include

QSslSocket::sslLibraryBuildVersionString()的值仍然是旧值"OpenSSL 1.1.1b 26 Feb 2019"，但是QSslSocket::supportsSsl()的值变成了true，这解决了我的问题。
