Using QSslSocket with custom OpenSSL

Opa114

Thanks! But why are my versions different?
I build Qt with OpenSSL 1.0.2j, so both outputs must be the same or not?

SGaist

Silly question but are you sure that you are using your self-build Qt in your kit ?

yes :)
could it have to do with Qt-Creator, which was build with another version?

SGaist

No, the Qt version used to build Qt Creator doesn't affect any any way the Qt version you are using with your kit.

Do you have another OpenSSL version installed on your system ?

on used to bui

no not installed like the precompiled OpenSSL Libraries. I searched the whole PC (Windows) for OpenSSL and libeay32.dll. I found many applications which are using OpenSSL but only one Application uses the specific OpenSSL version OpenSSL 1.0.2g 1 Mar 2016 i posted above. This Application is Adobe Lightroom.

Could this be the problem on building Qt that some shipped libeay32.dlls are used on build process?

@SGaist Sorry, i have the same problem.
When i print:
qDebug() << QSslSocket::supportsSsl(); ==> false
qDebug() << QSslSocket::sslLibraryBuildVersionString(); ==> "OpenSSL 1.0.2g 1 Mar 2016"
qDebug() << QSslSocket::sslLibraryVersionString(); ==> ""

and i obtain these messages:
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 have instaled only Qt 5.7 on Windows 7 32. What can i do?
Thanks

SGaist

Hi,

Do you have OpenSSL installed ? Built with the same compiler as Qt ? In a folder known to your application ?

CarlosQ

@SGaist No, no and no. Ohhhh. i'll try to build the libraries.

Sorry, thanks.

SGaist

You can find here prebuilt versions of OpenSSL for various compilers.

CarlosQ

@SGaist Thank you for the link. I was trying to build the libraries and I'm going crazy.

I have Qt 5.7.0 on a Windows 7 32 bits, which instalation should be correct?. I think "Win32 OpenSSL v1.1.0c". Is it ok?.

Thanks again.

SGaist

IIRC there was a renaming of the libraries of OpenSSL so you'll have to double check.
