Example Simpleselector not working

Kussi

Hi there,

I'm new to Qt. I got the Qt Creator, Qt 5.5 and MinGW as compiler.

When trying the example "simpleselector" i got the following problem.

Using the example as is in debug mode, the application won't work and it shows:

QNetworkReplyImpl::_q_startOperation was called more than once
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

I copied the DLLs libeay32.dll and ssleay32.dll from C:\Qt\Tools\QtCreator\bin into the debug-folder of the example. The application started, but windows told me after a few seconds it was not responding.

I tried the same using the profile Release and it worked like charm.

Then I tried a website, which doesn't use SSL in Debug-Mode and it worked also.

Does anyone now, if there are special configurations necessary or if there is a bug in the example.

Thanks for your help.

Hi and welcome to devnet,

Don't copy these DLLs, unless it has changed over time, Qt Creator is build with MSVC and you have a MinGW Qt build. You should rather get the official OpenSSL package and install that one to use with your application.
