Qt，Windows和OpenSSL-無法調用無法解析的函數xyz

Question

我最近在運行Qt 5.9.1的Windows 10計算機上安裝了ArcGIS Runtime SDK。 嘗試使用其中一個ArcGIS模板構建簡單的QWidget應用程序時，出現以下錯誤：

qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_new
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_library_init
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_new
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_library_init
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_new
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_library_init
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_new
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_library_init
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_new
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_library_init
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error
qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error

這個問題似乎很普遍，但是大多數Google結果為Linux系統提供了答案。

我已經完成以下工作：

• 下載並安裝了OpenSSL（來自GnuWin32 OpenSSL）
• 跨libeay32.dll和libssl32.dll復制到構建文件夾
• 在Qt pro文件中添加了include路徑
• 驗證network是否在pro文件的QT += config部分中

但是，以上所有內容都沒有任何區別。 我正在運行MSVC 2015 32位套件。

Answer 1

您必須將靜態庫添加到您的項目。

找出libeay32.lib和libssl32.lib並將它們添加到您的項目中。

參考

Answer 2

我認為你需要這樣的兩個DLL文件：的libeay32.dll和ssleay32.dll.I使用相同版本的QT你做，這樣你就可以下載它們在這里或直接從獲得的zip 這里 （這為我的作品）。

Qt使用了不同版本的openssl lib，因此，如果不確定，請使用下面的靜態函數在代碼中對其進行測試：

QSslSocket::sslLibraryBuildVersionString();
