      The summary file is pretty long, do I send it with the upload file option or are you just looking for specific parts of the file that I can relay to you?

        Currently I don't have any specifics in mind.

        I just realized something, the Moc message is correct, QCanFrameProcessor is indeed not a QObject based class.

        Can you build Qt with parallel at 1 ?

          @SGaist I did build Qt with parrallel, though I dont undesrstand what you mean by building it "at 1" forgive me for my need for specifics, I just dont know much about qt and I'm building it for specific capabilites only available to such version.

          Anyways could you elaborate on building it "at 1" ?

            Either remove parallel from the parameters or set its value to 1.

                  I have set it's value to one but I seem to have encountered the same build error.

                    if it means anything I did get this warning
                    while looking at the configure summary file:
                    "Required Python dependencies NOT found: spdx_tools.spdx.clitools.pyspdxtools"
                    While also getting this warning during the build process:
                    "WARNING: Support for linking against a C++ standard library other
                    than the one in-tree (buildtools/third_party/libc++) is deprecated
                    and support for this will end. We plan to remove this option in
                    M138."
                    Do you think any of these might be the source of my problem?

                      What errors do you encounter?

                      Those seems to be warnings.

                        @GrecKo the errors are stated at the top of the post but for clarification I get
                        these messages:

                          @SkeletonHorse Do any of you think that the required python dependencies here might be causing my issues? I have a feeling they are, though I am having trouble downloading the packages via sudo apt install so I haven't been able to test it.

                            Do any of you know how I can install these dependencies on ubuntu? I've tried pip install which is the general way to do it but doing so would cause conflicts on my OS, and I can't seem to find apt packages that have the equivalent to what I need. any helpful response would be appreciated
