      I am getting this error continuously while trying to build Qt5.9.5 source for Raspberry-Pi 3. What can be the possible reason ?

        hello guys , finally iam able to build Qt after making two blank files named
        1.) .qmake.stash
        2.) .qmake.super
        in build directory. So the problem is happening due to not creating this two files in the configuring step. I don't know why configuring script is behaving like this.

          Hi
          You are not stating Qt version, platform etc so hard to geuss at.

          Might be this ?

              @Vivx701 it looks like you're trying to cross compile (-device-option CROSS_COMPILE=...) so are you following this guide? It worked for me with Raspbian Stretch, Qt 5.10.1 and Pi Zero W
              Just in case, you stated "for Raspberry-Pi 3" but you shown configurating it for RPi 2 -> "-device linux-rasp-pi2-g++"

                  fedberry

                  Ok, it would be better to have stated it previously :-) (saving you and me a couple of posts...)

                  Even with that, I guess the suggested guide would still apply from step #5 onwards, wouldn't it?

                      @Vivx701 @Vivx701 Wow! it looks like you were super fast creating your sysroot and rscync'ing it.
                      Again, my suggestion is that you follow that guide step by step...

                            Hi,

                            You seem to be building Qt from within a directory that's inside the sources, is that correct ?

                            If so, then that's likely the problem. You should build Qt either within the top folder of the sources or even better in a folder outside of the sources.

                                  Are you doing that from clean sources ?

                                  If not, you should nuke them as well as the build folders you used and start over with an out of source build.

                                        Adding .qmake.super seemed that have fixed my issue as well. Has anyone found out why it wasn't created to begin with?

                                          Cloned GIT folder into Mint Linux 20, I had a failed configure in the root directory. Removed .qmake.super file from the root QT5 folder, then configured again within the QT5-build folder without error.
