    You should use the latest version of botan for security reasons.

    In any case, it's completely unrelated to my question: aare the architectures of your botan build and Qt the same ?

          Did you also compile botan with MinGW ?

              If you used nmake, it means that in fact you used Visual Studio to build botan. So there's your issue. You can't mix C++ code built with MinGW with C++ code built with Visual Studio.

              Tow options here:

              • rebuild botan using MinGW
              • change your Qt version and use the one that matches your Visual Studio version

                you recommend what version of qt for this?

                  As I said: the one matching your current version of Visual Studio.
