    @SGaist said in Cannot build QtWayland plugin when building qt from source for 32bit.:

    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 ?

            @SGaist

            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 ?

                    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.

                        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.
