    Hi
    Its not bad pr se, but i did burn my fingers using other version
    that the one Qt provides. One issue can be 64 bit but it seems you are using 32.
    so i would try the included mingw.
    I know the test is not trivial due to huge compile times:)

            Hi @mrjj, finally done!

            But just a empty qtquick App 600Mo ?

            I knew static makes the executable bigger but i was not expecting 600mo. There must be some techniques to optimise the executable size, no ?

            edit : actually that was a debug build, release version is 20Mo

            @mrjj meny thx for help

              Good work :)
              and yes, debug builds are amazingly fat.

                  I would check where you had build folder. it most like is in that folder too.
                  Seems a bit big :)
                  So there might be tons of .o files etc remaining.

                      Hi,

                      Always build with -nomake tests -nomake examples especially when doing a static build.
