    @SGaist Yup, configure ran cleanly through this time, first try. Assuming the gmake works, I'm wondering about this bit:

    Qt is now configured for building. Just run 'gmake'.
    Once everything is built, you must run 'gmake install'.
    Qt is now configured for building. Just run 'gmake'.
    Once everything is built, you must run 'gmake install'.
    Qt will be installed into
    
    Prior to reconfiguration, make sure you remove any leftovers from
    the previous build.
    

    That line that says "Qt will be installed into" just ends in space. Have I missed something else now?

    If you used the same line as in your initial post, you are doing a developer build and hence it won't be installed. It's an "in place" build.

    Unless you want to hack on Qt, you should drop that option as it changes some flags (I don't remember which though).

      As for the bootstrap error, are you using a multithreaded build ? I do not see the error trigger the stop.

        @SGaist "If you used the same line as in your initial post"
        Arrgh, yes I did. OK, we start over again. This time:

        /opt/qt5/qt5-build $ ../configure  -opensource -nomake examples -nomake tests -platform solaris-g++
        

        This also worked. Now starting gmake -j16 again.
        UPDATE:
        It just doesn't seem to like qvncscreen.cpp:

          frameBufferLittleEndian

          You might be the first person building that plugin on a big endian system.

          AFAIK, that call should be commented out with a Todo comment and the method do nothing and return false.

          I'd recommend doing that so your build can continue.

            I was actually wondering about that. So I've now changed that block at the end of qvncscreen.cpp to read

            #if Q_BYTE_ORDER == Q_BIG_ENDIAN
            bool QVncScreen::swapBytes() const
            //bool QVNCScreen::swapBytes() const
            {
                if (depth() != 16)
                    return false;
            
            //    if (screen())
            //        return screen()->frameBufferLittleEndian();
            //    return frameBufferLittleEndian();
                return false ;
            }
            #endif
            

            Now we're getting

            /opt/qt5/qtbase/src/plugins/platforms/vnc/qvncclient.cpp:642:9: error: ‘qvnc_screen’ was not declared in this scope
              642 |     if (qvnc_screen->swapBytes())
            

            I'll have to see if qvnc_screen is actually declared anywhere.

              I had to comment this out in qvncclient.cpp (probably not a good thing to do but I don't know what this is for and I don't really need VNC in QT anyway)::

              #if Q_BYTE_ORDER == Q_BIG_ENDIAN
                  //    m_swapBytes = qvnc_screen->swapBytes();
              #endif
              

              Now it's finally linking but still not happy with some qtserialbus stuff:

              I'm not particularly interested in the serial bus. Can I exclude this somehow? I grepped the configure --help for "serial" but came up empty.

                You can add a -skip <module_to_skip> to the configure command for all modules you do not want to build.

                When you have such build error, you should restart the build single threaded so you get the exact point where it failed. Here it is lost somewhere in one of the threads used for the build process.

                    The skip option is only for module names.

                    As for the Qt declarative issue... gcc 10 is supported on Linux so it does look a bit strange...

                      What name should I give configure -skip to exclude the requirement for libQt5SerialPort.so?
                      Oh wait a minute, I do have that library:

                      /opt/qt5/qt5-build/qtserialbus/lib $ ls
                      cmake                     libQt5SerialBus.so        libQt5SerialBus.so.5.8.0
                      libQt5SerialBus.la        libQt5SerialBus.so.5      pkgconfig
                      libQt5SerialBus.prl       libQt5SerialBus.so.5.8
                      /opt/qt5/qt5-build/qtserialbus/lib $
                      

                      So why is it saying:

                        "-skip qtserialbus" for example.

                        Looks like your machine goes too fast :-D

                        Try building the qtserialport module before qtserialbus

                        You can use "make -C qtserialport" and then go on with your build.

                          @SGaist That worked:

                          /opt/qt5/qt5-build $ gmake -C qtserialport
                          gmake: Entering directory '/opt/qt5/qt5-build/qtserialport'
                          cd src/ && ( test -e Makefile || /opt/qt5/qt5-build/qtbase/bin/qmake -o Makefile /opt/qt5/qtserialport/src/src.pro -qtconf /opt/qt5/qt5-build/qtbase/bin/qt.conf -- -opensource -nomake examples -nomake tests -platform solaris-g++ ) && gmake -f Makefile 
                          gmake[1]: Entering directory '/opt/qt5/qt5-build/qtserialport/src'
                          cd serialport/ && ( test -e Makefile || /opt/qt5/qt5-build/qtbase/bin/qmake -o Makefile /opt/qt5/qtserialport/src/serialport/serialport.pro -qtconf /opt/qt5/qt5-build/qtbase/bin/qt.conf -- -opensource -nomake examples -nomake tests -platform solaris-g++ ) && gmake -f Makefile 
                          gmake[2]: Entering directory '/opt/qt5/qt5-build/qtserialport/src/serialport'
                          gmake[2]: Nothing to be done for 'first'.
                          gmake[2]: Leaving directory '/opt/qt5/qt5-build/qtserialport/src/serialport'
                          gmake[1]: Leaving directory '/opt/qt5/qt5-build/qtserialport/src'
                          gmake: Leaving directory '/opt/qt5/qt5-build/qtserialport'
                          /opt/qt5/qt5-build $
                          

                          I'm doing the gmake over again without -j anything. Even though I don't think -j16 is particularly ambitious, sometimes it gets ahead of itself. It just takes forever with only one CPU on the job.

                            What I do is usually start with multithreaded and if it fails go back to single threaded, fix the issue and start again with multithreaded.

                              I've started doing that too. In any case, with this:

                              /opt/qt5/qt5-build $ ../configure  -opensource -nomake examples -nomake tests -platform solaris-g++ -skip qtserialbus
                              

                              we're now going much further but are not there yet.

                                That one is just a warning. Does it error out on this warning ?

                                    I think your error has also been reported in this forum:

                                    @SGaist was going to deal with that topic back in 2017 :)

                                      Well that makes two of us. In my own search, this seems to suggest it's a programming error:

                                        Yes, it's a programming error in the code which only shows up on certain architectures. Why it has not been picked up in whatever version you are building (which is that?) I do not know.

                                        While building qt5 in Solaris 11.4 SPARC, I get:

                                        Not that I know about these things, but then are you "MIPS"?

                                          Nop, he's SPARC.

                                          As for that issue, coming from ASSIMP, it's likely something you should bring to their folks.

                                          Sadly I do not have a big endian machine to check further what is going on there.
