    @gogoer If you copy/past the path to compiler into a terminal: does it start/run?

            @gogoer said in Installation QT 5.11 on Raspberry Pi 3:

            libz.so.1: cannot open shared object file: No such file or directory

            Where is your sysroot and does it contain libz.so.1?

                I compiled my project and copy executable file to RPI.
                But when I execute it, i have error

                *failed to add service - already in use?
                

                it crashes on function

                QGuiApplication app(argc, argv);
                

                and one more question: i create and install qt5.10 on ubuntu, what i need to do to update qt version on RPI? as i understand it still uses old version.

                  @gogoer I don't know what "service" is mentioned in the error.
                  "install qt5.10 on ubuntu, what i need to do to update qt version on RPI" - do you mean you cross-compiled Qt 5.10 on your Ubuntu machine? If so you can copy the libs to the same location or RPi you defined using -prefix parameter.

                      i created blank QTQuick application and compile it.
                      when i start it on RPI have error:

                      QML debugging is enabled. Only use this in a safe environment.
                      * failed to add service - already in use?
                      

                      one more question:
                      where i can configure path to copy on RPI? now after pressing Run button executable file copies to /opt/ directory on ubuntu. i want to change it, but cant find where to do this.

                        @gogoer Come on, you're already using -prefix parameter:
                        "../qt-everywhere-src-5.11.2/configure -v -opengl es2 -eglfs -no-gtk -device linux-rasp-pi-g++
                        -opensource -confirm-license -reduce-exports
                        -force-pkg-config -nomake examples -no-compile-examples -release
                        -qt-pcre -ssl -evdev -system-freetype -fontconfig -glib -prefix /opt/qt5"

                        So, you should copy Qt to /opt/qt5

                          i compiled all by this manual: http://ulasdikme.com/projects/raspberry/Qt_for_raspberrypi.php
                          i used:

                          ../qt-everywhere-src-5.10.1/configure -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- -sysroot /opt/qt5pi/sysroot -prefix /usr/local/qt5pi -opensource -confirm-license -skip qtscript -nomake examples -make libs -pkg-config -no-use-gold-linker -v
                          

                          i have qt libs on /usr/local/qt5pi on my RPI.

                          if i compile project on PRI natively and run it works.
                          but if i compile same project on ubuntu and copy executable file to RPI it gives error:

                          * failed to add service - already in use?
                          

                          maybe i need to copy something else?

                            i have qt libs on /usr/local/qt5pi on my RPI.

                            if i compile project on PRI natively and run it works.
                            but if i compile same project on ubuntu and copy executable file to RPI it gives error:

                            * failed to add service - already in use?
                            

                            maybe i need to copy something else?

                            @gogoer What service is it talking about? What is your application actually trying to do? Maybe cut it down to a helloworld app to test with and make sure Qt is working properly. Or at least add logging to your application so you can see at what point it comes up with that error.

                            Also you can try running strace on your exe to see what it is trying to do when it fails. Sometimes that will give you some insight.

                            I've never seen that error from Qt. And I've used it for like 18 years now.

                            Edit: Ah this makes sense now ... it's a Pi thing.

                            That's an old topic but it should give you some ideas.. Seems to have to do with memory.

                              @ambershark said in Installation QT 5.11 on Raspberry Pi 3:

                              What service is it talking about? What is your application actually trying to do? Maybe cut it down to a helloworld app to test with and make sure Qt is working properly.

                              I created a blank QTQuick project with only HelloWorld window and it gives such error, when i start it. Error crashes on

                              QGuiApplication app(argc, argv);
                              

                              function.

                              But if i create or compile project on RPI (it uses QT5.3 and QTCreator1.2.3) everything works well.

                                What does ldd <yourexe> show (the exe you loaded on the Pi)? I wonder if you're missing a library or it's mixing Qt versions on the Pi and the ones you loaded.

                                    @gogoer All that looks ok. Figured you would have mixed libraries. You can dig deeper by running ldd on each Qt lib but I don't think it will show what i was expecting.

                                    Can you run it in a gdb and dig into the part of the code that is causing that failure? I know you said it was in QApplication but can you provide any more information? If not I don't have any more ideas ... it seems like it was compiled or installed incorrectly on the Pi but I don't know why.

                                      thank you very much for help.
                                      i reinstalled ubuntu and Raspbian and everything compiles well.
                                      now when i try to start application on RPI i have next error:

                                      Unable to query physical screen size, defaulting to 100 dpi.
                                      To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).

                                      i inderstand that it cant find some libs but dont know where to fix this.

                                        i want to use Gauge control, so i write in main.qml:

                                        import QtQuick 2.11
                                        import QtQuick.Window 2.1
                                        import QtQuick.Controls 2.4
                                        

                                        i installed QT 5.11.

                                        i checked folder /usr/local/qt5pi/qml/QtQuick.2
                                        and ith have only 3 files, no folders with controls. is it normal?

                                          i created blank QTQuick application in QTQreator, it compiles good, but when run it gives errors (see upper).
                                          i check it with ldd:

                                          i checked /usr/local/qt5pi/lib/libQt5Quick.so.5 path, it is ok.
                                          what can be wrong?
