    Dear Sirs,

    I follow this guide to create cross-compiler successfully:
    https://wiki.qt.io/Raspberry_Pi_Beginners_Guide
    In this guide, there is a configuration as below:

    ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi make -j 4 
    

    I can create and run a simple application successfully. However if my project use more modules, the compiler will fail.
    For example:

    QT += core gui            //This is OK
    QT +=core gui serialport  // Fail
    

    qml and multimedia also not working on my project.

    Should I add modules on "./configure " ? I check "./configure -help" but there is no "-serialport" or "-qml".
    I have no idea how to proceed.

    Is there anyone know to to add more modules ?

    Thanks,

      Dear All,

      I found this page : https://www.ics.com/blog/building-qt-5-raspberry-pi
      it says:

      $ cd qt-everywhere-opensource-src-5.0.2/<module>
      $ /usr/local/Qt-5.0.2-raspberry/bin/qmake
      $ make
      $ sudo make install
      

      so I run above command accordingly, the log in below link :
      https://www.dropbox.com/s/7g6f8ay8rjaruqa/make_qt_modules.txt?dl=0

      I see no error, but when I go back to run QT creater, QT still report :

      error: Unknown module(s) in QT: serialport
      

      Any suggestions ?

        Hi,

        Did you re-run qmake after installing the module ?

          Dear @SGaist ,

          Yes, after make install (in module folder), I open QT Creater then run clean and build.
          But QT Creator still cannot recognize serialport module.

          PS. I also tried to run "run qmake" from right click menu before build, the result is the same.

            Did you check the content of your cross-compiled Qt installation ?

              Dear @SGaist ,

              Do you mean the content of "qt5/qtbase/include" ?
              In this folder, I don't see "QTSerialPort" or anything related to serialport folder.

              Is there anything wrong ?

                @Hiloshi According to the log you posted it should be in /home/hiloshi/rpi/rasp-pi-rootfs/usr/local/qt5pi/include/QtSerialPort

                  Dear @jsulm , @SGaist ,

                  Inside the folder, there are:

                  hiloshi@ubuntu64:~/rpi/rasp-pi-rootfs/usr/local/qt5pi/include/QtSerialPort$ ls
                  5.8.0                QSerialPortInfo      QtSerialPortVersion
                  QSerialPort          qserialportinfo.h    qtserialportversion.h
                  qserialportglobal.h  QtSerialPort
                  qserialport.h        QtSerialPortDepends
                  
                  

                  Inside the 5.8.0, there are:

                  hiloshi@ubuntu64:~/rpi/rasp-pi-rootfs/usr/local/qt5pi/include/QtSerialPort/5.8.0/QtSerialPort/private$ ls
                  qserialportinfo_p.h  qserialport_p.h  qtudev_p.h
                  
                  

                  The above data are in the host side raspbian-jessie.img(mount as rasp-pi-rootfs folder).

                  Does it mean install successful ?

                    Looks like it yes.

                    Just to be sure, you are are sure you are using the correct qmake for your project ?

                      Dear @SGaist ,

                      I think there are something wrong on the way I create project.

                      I import example project from:

                      ~/rpi/qt5/qtserialport/examples/serialport/terminal
                      

                      and try build and run --> It is working ~~~

                      But then I try to create project again, it still show:

                      Project ERROR: Unknown module(s) in QT: serialport
                      

                      The way I create project is:

                      1. select Qt Widgets Application
                      2. input project name
                      3. Select Kit (Raspberry Pi)
                      4. Choose base class "QMainWindow"
                      5. Add serialport to the end of "QT += core gui " on pro file
                      6. Build

                      I compare the pro file of two project, I cannot see the mistake.

                      I upload the project: https://www.dropbox.com/s/fn85bcptzl2pa9k/serialport_test.rar?dl=0
                      Inside the rar, "terminal3" is working project, "terminal" is not working.

                      Any suggestion is appreciate.

                      Thanks,

                        What do you mean by importing ?

                        Take a look at header of the Makefile of the two projects, the qmake line used for each is pretty different.

                          Dear @SGaist ,

                          Sorry, it should be "Open Project" not import.

                          I may find the reason that cause this issue:

                          If I put my project into below folder, then build is OK:

                          ~/rpi/qt5/qtserialport/examples/serialport/terminal/
                          

                          If I put project on my original workspace, compiler will fail:

                          ~/rpi/QT5Projects/
                          

                          So I feel I may not include correct path into project.
                          I go through the options on qt creator, unfortunately I didn't find the place to add path.

                          How should I do to fix it ?

                              I don't familiar with command line operation, but I will check some document and try.

                              Do you suspect something wrong with QT Creator ?

                              Thanks,

                                @SGaist said in How to add new module ?:

                                Just to be sure, you are are sure you are using the correct qmake for your project ?

                                I think you are correct, I use the wrong qmake.

                                My original setting about "qmake location"(in Options->Build&Run->QtVersion) is

                                ~/rpi/qt5/qtbase/bin/
                                

                                but when I build qbase, I use:

                                ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$(which arm-linux-gnueabihf-gcc | sed 's/.\{3\}$//') -sysroot $RPIIMG -opensource -confirm-license -optimized-qmake -reduce-exports -release -no-qml-debug -make libs -make examples -prefix /usr/local/qt5pi -hostprefix $RPIQT
                                

                                the -hotprefix is $RPIQT, this location is:

                                ~/rpi/qt5pi/bin/
                                

                                So I should use ~/rpi/qt5pi/bin/ .

                                Can you try from the command line directly ?

                                I found this by using command line:

                                1. $RPIQT/bin/qmake .
                                2. make

                                I see no error message so I goback to check qmake location and find this error.

                                Thank you very much.
