    Hi,

    Unrelated to your issue, unless you plan to hack on Qt itself, drop the -developer-build option.

    the man, the myth, the legend, @SGaist

    I'm currently building with that option enabled. Does it alter qt in any major way? Or is it fine to use a build that has that option?

      @logan-massey it modifies some of the flags used for the build (sorry I don't remember the details right now). The point is that the build is not optimized as a release build which is what you want to have for building and distributing your applications.

          Hello @logan-massey,
          you are getting this two error because your Qt source code build is not generated xcb and wayland flatform libraries.

          sudo apt-get install build-essential libgl1-mesa-dev
          try the above common for build essentials. in configure commond add both wayland and xcb.
          example - ../configure -prefix pathtoinstall -xcb -xcb-xlib -bundled-xcb-xinput -developer-build -wayland -- -DQT_BUILD_TESTS_BY_DEFAULT=OFF

          @Durugesha @ChrisW67 So currently while trying to configure with these flags "-xcb, -xcb-xlib, -bundled-xcb-xinput", I get the following 2 errors:
          35e046f9-85f0-4f6e-bd0c-4572f51bef72-image.png

          I also figure this would be relevant, what can I do to ensure these (xkbxommon-x11,, and xcb-sm) are "yes" ?
          7c0915b2-051a-4dff-915e-6e0aaa736c5b-image.png

          When in fact i have this installed already
          651a931b-7343-41db-b72f-78a684b22ea0-image.png

          Also, qtwayland says it is still missing required dependencies:

          Thank you for your help!

            Hi,

            Did you restart the configuration from a clean state after installing the missing dependencies ?

              I delete all folders in the build folder. And start a new terminal. Is that enough?

              Once I removed the -developer-build option from the configure line, like you suggested earlier, I started getting those "Forcing to ON breaks its condition" errors, so I am only using the -bundled-xcb-xinput option.

              Also, I am skipping a good amount of modules to keep the space it takes up fairly low and since I have encountered errors building all of them in the past. Here is a screenshot of my full configure line:

                Check the logs generated from the configure tests, they might give you more hints about what is going wrong.

                  @SGaist
                  After a break from this, I am back and retrying. This is where I stand now. Help would be much appreciated as I am a little naive with this topic. Thanks

                  I do not see any log files. Only file i see is the config.summary file. Which only mentions wayland once
                  3c667f4f-0810-41b6-9359-c3c0bf2afcae-image.png

                  The configure output throws this warning:
                  66833ead-815e-4f1a-b5ac-f5f9bf3d1bbc-image.png

                  When I go to that file and look at line 26, I see this conditional:
                  1bac9130-b3f2-406e-b1ee-08b624d77ba0-image.png

                  I can confirm I have WaylandScanner:
                  9875128c-4d76-43e0-b7e0-8789a1e42a2b-image.png

                  And this shows I am using Wayland:
                  f852c5d8-1236-47a2-8a3b-1d63055e86c8-image.png

                  So to figure out which conditional was failing, I modified the CMakeLists.txt in the wayland/src folder by splitting the conditional into two if statements:
                  ce48d163-db6b-4e2d-bcd9-4ac8bd50ac40-image.png

                  After running the configure script again with this new CMakeLists.txt file, I see this:
                  f63df84d-dde2-4805-8215-11704814fcde-image.png

                  This tells me that the NOT Wayland_FOUND conditional is what is throwing this. I'm not positive what this means since I am running Wayland already since it comes with Ubuntu pre-installed.

                    Do you have the wayland development libraries installed ?

                      @SGaist

                      The Wayland Development libraries I already have installed are as follows:

                      libwayland-dev
                      libffi-dev
                      libwayland-bin
                      libwayland-client0
                      libwayland-cursor0
                      libwayland-egl1
                      libwayland-server0
                      libwayland-doc

                        I just saw that the cmake file looks for 1.15 and you have wayland 1.20. I wonder if it comes to that.

                          @SGaist
                          spent yesterday working on this suggestion. Got wayland1.15 built and installed.

                          I ran the configure script for qt and didnt see any issues with configuring the qtwayland module. Started building and it failed with this error:
                          b292b078-0f03-432f-9426-eeab6bbdb889-image.png

                          before it failed, it spit out these warnings:
                          03e90e7f-5e7e-4ef4-ac53-fde048d6dc95-image.png

                          I was trying to open a log file to see if it would give me any more info, but it wasnt opening. So I restarted my VM, and now I get a blinking cursor on a black screen. I feel the issue may be that my version of ubuntu is incompatible with wayland 1.15. Trying to see what I can do to save this machine.

                            As a first step, I would have adapted the script to the version of wayland installed and not replace any system components like that.

                            What you can do is switch to one of the virtual terminal and force reinstall wayland.

                            Another possibility is to ssh into the system.
