Qt - SLL error on Windows

My app is throwing the following errors on windows:

QSslSocket: cannot call unresolved function SSLv3_client_method

QSslSocket: cannot call unresolved function SSL_CTX_new

QSslSocket: cannot call unresolved fun开发者_高级运维ction SSL_library_init

QSslSocket: cannot call unresolved function ERR_get_error

QSslSocket: cannot call unresolved function ERR_error_string

I have already installed the VS C++ Redistributables and OpenSSL but I have no idea on how to tell Qt to link against openSSL dynamically. I'm using the LGPL version of the Qt binaries and Qt Creator all on Windows 7 (the Linux build works just fine)

For some reason Qt wasn't dealing very well with the dlls downloaded from Win32 OpenSSL Installation Project. As I had observed that the application ran smoothly on machines with Tortoise Svn installed I just copied the dlls provided with Tortoise and this worked very well for me.

I know, it's weird that those dlls worked and those from the Win32 OpenSSL Installation Project didn't but for now copying the dlls from the Tortoise Svn installation folder solved my issue.

Download the the latest OpenSSL pre-build binaries from this website.

I used Win32 OpenSSL v0.9.8r Light as there is some debate about the v1 release. [Client tools are fine you don't need the full distribution]

Make sure that you install the dlls so that they are visible in the windows path. Either;

• the windows / system32 directory
• the application directory
• or add the location of the dlls to the path enviroment variable

This works for me with Qt v4.6.2
