    Hi
    Got same result as you in step 6.
    I used 5.4.0 as in tut.

    After qmake which says nothing no moc file is
    generated and mingw32-make fails and no qsqlcipher.dll is produced.

    I then tried to create a moc by "moc.exe smain.cpp > smain.moc" and then copy that around but
    either i did not hit the right directory or its not ok to create it like that. Still same error.

    One should think that smain.cpp that do #include "smain.moc" should find it in same folder but
    maybe I should have tried with full path to the file.

    I have a feeling it is something really simple that will make us go facepalm once discovered.

      @mrjj Thank you for your help and time,

      what do you think, is it a bug in the qmake ?

      Pardon my English
      Thank you.

        Np, i can see the benefit of encrypted sqlite.

        Not sure it is a bug in qmake.
        More likely something with the PRI/PRO file but it does seem like qmake just sort of bails out.

        Im going now for a B.day but when i get home I going to try one more time. If same result it must be
        an build error.

          Ok, did it once more after some beers and it build ?!
          No errors.

          I have shared the DLLs (debug/release) and the A files here:
          https://www.dropbox.com/s/k1jm5qv7mvdyyzn/sqldrivers.zip?dl=0

          Cheers :)

                    Hi, I did the rest of the tut and
                    it did produce an encrypted db.

                    but, then i tried to use the test .pro and main.cpp i got same
                    error "driver not loaded"

                    I tried to find a fix but seems not to see the new dlls.
                    Not even if you make a Deploy folder with all the needed files.

                    I think its just a path problem like here
                    http://stackoverflow.com/questions/14362881/qt-mysql-cant-load-plugin-driver-qlibrary-qpluginloader-successfuly-loaded-qs

                    But I had time to try load the DLL which works. Did not try the add path etc.

                      @mrjj I tried the solution, it doesn't work.

                      And I tried the sqlite default driver qt provided it's works perfectly.

                      Pardon my English
                      Thank you.

                        Ok, very strange.
                        Im out of ideas why it will not load as driver.

                        The .a +.exe could produce a encrypted db and the dll can be loaded as DLL but
                        for some reason, it wont load as a sql driver.

                        So close and yet nothing :(
