    @SGaist said in Rotate Qt app in framebuffer.:

    Hi,

    Looks like you would need to apply the patch you can find here to the linuxfb backend. It's the first one on the list.

    Can you tell me how exactly I should do it? I downloaded the patch and not sure what I should do next. Where do I put it? To the qt directory where the configure file is? Then I should run the commands:

    git init
    git apply --stat <patch_name>
    git apply --check <patch_name>
    git am --signoff < <patch_name>
    

    ?
    And then recompile the whole Qt?
    Thanks.

      Yes, did you try?

        Yes, and after git apply --check I get:

        error: recipes-qt/qt5/qtbase_git.bb: No such file or directory
        

        I don't have anywhere in my qt dir file named qtbase_git.bb. I downloaded qt with:

        sudo wget http://download.qt.io/archive/qt/5.15/5.15.0/single/qt-everywhere-src-5.15.0.tar.xz

          @Piotrrr I think you can remove "diff --git a/recipes-qt/qt5/qtbase_git.bb b/recipes-qt/qt5/qtbase_git.bb" part from the patch.

            After removing "diff" I still get the problem because at lines 208-209 there are:

            --- a/recipes-qt/qt5/qtbase_git.bb
            +++ b/recipes-qt/qt5/qtbase_git.bb
            

            which have the same directory. Of course can't remove these because then I get:

            error: patch fragment without header at line 209: @@ -31,6 +31,8 @@ SRC_URI += "\

              Make a file only containing the part relevant to 0001-Fix-the-qt5.6-linuxfb-ratation-problem.patch

              Then apply that smaller patch.

                I'm not sure which lines I can remove and which I shouldn't. I removed everything between line with "+2.7.4" (line 125) and the last line in the file with "+PR = "r2"". The commands with "--stat" and "--check" passed but at the git am --signof < fileName I get output:

                meta-qt5-qtbase-Fix-the-qt5-linuxfb-ratation-problem.patch:28: trailing whitespace.
                 
                meta-qt5-qtbase-Fix-the-qt5-linuxfb-ratation-problem.patch:40: trailing whitespace.

                meta-qt5-qtbase-Fix-the-qt5-linuxfb-ratation-problem.patch:74: trailing whitespace.

                warning: 14 lines add whitespace errors.
                

                Did this apply succeded? Can I now recompile Qt?

                  If you do a git diff what do you get ?
                  If you see the changes required then just go and build.

                    When I do git diff I get nothing, I built it but nothing has changed, rotation still doesn't work.

                      Then the patch was not applied.

                      That thing is really simple. If you do not manage to apply it, do the corresponding changes yourself in the files.

                        Then I'll try do it yourself. Thanks for the help.
                        Edit:
                        I made the changes myself and it works, app rotates. Thanks once again.
