    Hi,

    To add to @raven-worx, are you sure that your OpenSSL libraries are built for MinGW and in 32 bit ?

    @SGaist
    OpenSSL binaries should only expose a C-interface, so there shouldn't be a problem regarding this.
    I know that the 1.1.x libraries do append -x64 in the library filename, but i don't know if that was also the case prior v1.1.x

      @TheMushroom
      oh... the Modules panel is hidden by default.
      You can make it visible from the menu (Window -> Views -> Modules)

      Did you override the run environment (in the project settings) - specifically the PATH variable - maybe?

      For some reason my Window->Views button is greyed out and can't be clicked.

      Is this the "project settings" tab? :

      There doesn't seem to be any upper case PATH value, only a "Path" one.

      @SGaist
      I'm not sure what they were compiled for actually. I downloaded them off this site.

        you need to be in the Debug view (big Tab selected on the left side), then the menu item is enabled.

        Is this the "project settings" tab? :

        yes. Your environment isn't overridden.

        I downloaded them off this site.

        I just used OpenSSL today successfully with Qt 5.10.1 and mingw. I've downloaded it from here.

          @raven-worx indeed there shouldn't. However it's usually better to have everything from one compiler if possible to avoid surprises.

          I was also thinking about 32 VS 64 bit builds.

            How would I link the OpenSSL to Qt?

            I tried using the "Add Library..." feature in Qt, which generated the following lines in my .pro file:

            win32:CONFIG(release, debug|release): LIBS += -LD:/OpenSSL-Win32/lib/MinGW/ -lssl-1_1
            else:win32:CONFIG(debug, debug|release): LIBS += -LD:/OpenSSL-Win32/lib/MinGW/ -lssl-1_1d
            else:unix: LIBS += -LD:/OpenSSL-Win32/lib/MinGW/ -lssl-1_1
            
            INCLUDEPATH += D:/OpenSSL-Win32/include
            DEPENDPATH += D:/OpenSSL-Win32/include
            
            win32:CONFIG(release, debug|release): LIBS += -LD:/OpenSSL-Win32/lib/ -llibcrypto
            else:win32:CONFIG(debug, debug|release): LIBS += -LD:/OpenSSL-Win32/lib/ -llibcryptod
            else:unix: LIBS += -LD:/OpenSSL-Win32/lib/ -llibcrypto
            
            INCLUDEPATH += D:/OpenSSL-Win32/include
            DEPENDPATH += D:/OpenSSL-Win32/include
            

            I also added the libssl-1_1.dll and libcrypto-1_1.dll into the same places as I did with the libeay32.dll and ssleay32.dll files.

            Still the same errors :(

              You don't link. By default Qt loads the OpenSSL .dll.

              However from the looks of it, you downloaded the 1.1 series which is not compatible with the 1.0.

                for that you would have to reconfigure and recompile Qt. As @SGaist said by default the OpenSSL libs are loaded dynamically.

                What does the modules view show now?

                      Had the same problem. Thought I was on MinGW, but somehow was on MSCV2015. Switching the Kit (back) to Desktop Qt 5.10.1 MinGW 32bit did the trick for me.

                                    You can use QSslSocket:: sslLibraryBuildVersionString to ensure which version was used.

                                      i made a function to send sms and when i click on the pushbutton it always shows me this errors :
                                      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

                                        Have you tried the steps above? How did you install Qt? Is OpenSSL installed/available?


                                        If debugging is the process of removing software bugs, then programming must be the process of putting them in.
