    Then ran

    -Inspiron-3558:~/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard$ make

    Now i am getting below mentioned error.

    g++ -c -pipe -O2 -std=c++1z -fvisibility=hidden -fvisibility-inlines-hidden -fno-exceptions -Wall -W -Wvla -Wdate-time -D_REENTRANT -fPIC -DQT_VIRTUALKEYBOARD_DEFAULT_STYLE="default" -DQT_VIRTUALKEYBOARD_DESKTOP -DQT_VIRTUALKEYBOARD_HAVE_XCB -DQT_NO_EXCEPTIONS -D_LARGEFILE64_SOURCE -D_LARGEFILE_SOURCE -DQT_NO_DEBUG -DQT_PLUGIN -DQT_QUICK_LIB -DQT_GUI_LIB -DQT_QML_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -I. -I/home/user/Qt5.8.0/5.8/gcc_64/include -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtQuick -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtGui/5.8.0 -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtGui/5.8.0/QtGui -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtGui -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtQml -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtNetwork -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtCore/5.8.0 -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtCore/5.8.0/QtCore -I/home/user/Qt5.8.0/5.8/gcc_64/include/QtCore -I.moc -isystem /usr/include/libdrm -I/home/user/Qt5.8.0/5.8/gcc_64/mkspecs/linux-g++ -o .obj/inputcontext.o inputcontext.cpp

    Qt5.8.0/5.8/gcc_64/bin/qmake

    I thought you want to build for your target device using your cross compiled Qt 5.4? Now you're building for desktop Qt 5.9. What do you want to do?

        Like I already wrote: use the full path to the qmake executable matching the version of Qt you want to build the module for.

        Also, use out of source builds since you are going to compile for several platforms, that will avoid "polluting" the source tree with build artefacts.

          Use the full path?.

          can u explain this well Qt5.8 is installed in home directory i am using fullpath only.
          /home/user/Qt5.8.0/5.8/gcc_64/bin/qmake

            Just to be sure, are we clear that this one will only be valid for building the module for your Qt 5.8 installation ?

            By the way, what version of g++ are you running on your machine ?

                  @Pradeep-Kumar Make sure you're building from a clean state!
                  What I mean: if you don't use out of source build then extract the source code archive again and try to build again. Better to use out of source builds as @SGaist suggested.

                      I used qtvirtualkeyboard source code , moved out into different folder, followed the same steps .
                      Still same getting

                      g++: error: unrecognized command line option ‘-std=c++1z’

                        I think they should be the same but can you just check that g++ is the same version as gcc ?

                          Both are same versions.

                          4.8.4-2ubuntu1~14.04.3

                            From the supported platform 5.9 is at Ubuntu 16.04. You're version of g++ is a bit outdated in that regards so you'll have to modify the mkspec a bit to remove the date-time warning as well as change the c++1z with something a little older like c++14.

                              Hi,

                              I have updated g++,

                              gcc version 5.4.1 20160904 (Ubuntu 5.4.1-2ubuntu1~14.04)
                              gcc version 5.4.1 20160904 (Ubuntu 5.4.1-2ubuntu1~14.04)

                              gcc is same as g++,

                              still i am unable to achieve it.

                              1. i used qmake
                                -Inspiron-3558:~/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard$ /home/user/Qt5.8.0/5.8/gcc_64/bin/qmake

                              2. then used make

                                HI,

                                I installed latest g++ and gcc versions and

                                1. used qmake.
                                2. then make clean.
                                3. then make.
                                4. make install.

                                Then ran the basic program which is present in the path
                                /home/user/Qt5.8.0/5.8/Src/qtvirtualkeyboard/examples/virtualkeyboard/basic

                                I am getting virtual keyboard in ubuntu,
                                Thanks for the solutions and help,

                                But when i change the language present in the path,
                                /home/user/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard

                                as CONFIG += lang-ar_AR in the virtualkeyboard.pro file,

                                then again followed the steps to compile the plugin,
                                but when i ran the basic program to launch virtual keyboard, i am not getting the button enabled, to select the language,

                                Please provide the guidance,

                                Thanks,

                                  Hi,

                                  I have updated g++,

                                  gcc version 5.4.1 20160904 (Ubuntu 5.4.1-2ubuntu1~14.04)
                                  gcc version 5.4.1 20160904 (Ubuntu 5.4.1-2ubuntu1~14.04)

                                  gcc is same as g++,

                                  still i am unable to achieve it.

                                  1. i used qmake
                                    -Inspiron-3558:~/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard$ /home/user/Qt5.8.0/5.8/gcc_64/bin/qmake

                                  2. then used make

                                  -Inspiron-3558:~/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard$ make
                                  rm -f libqtvirtualkeyboardplugin.so

                                  @Pradeep-Kumar said in Example of Virtual Keyboard showing in different languages:

                                  .obj/platforminputcontext.o: error adding symbols: File in wrong format

                                  you should do it from a clean state - looks like you have binaries built with the old compiler.

                                      AFAICS you are setting only one language when building the module. You should list all the languages you want to support.

                                        nope still the same, i provided 4 languages in .pro file,

                                        still the same issue.

                                        when i run make install

                                        -Inspiron-3558:~/Qt5.8.0/5.8/Src/qtvirtualkeyboard/src/virtualkeyboard$ make install
                                        install -m 755 -p ../../plugins/platforminputcontexts/libqtvirtualkeyboardplugin.so /home/user/Qt5.8.0/5.8/gcc_64/plugins/platforminputcontexts/libqtvirtualkeyboardplugin.so
                                        strip --strip-unneeded /home/dheerendra/Qt5.8.0/5.8/gcc_64/plugins/platforminputcontexts/libqtvirtualkeyboardplugin.so
                                        install -m 644 -p /home/user/Qt5.8.0/5.8/Src/qtvirtualkeyboard/lib/cmake/Qt5Gui/Qt5Gui_QVirtualKeyboardPlugin.cmake /home/dheerendra/Qt5.8.0/5.8/gcc_64/lib/cmake/Qt5Gui/

                                        after this i run sample program.

                                        Thanks,

                                          The Qt open source package contains the qtvirtualkeyboard component.
                                          I can build it without anu problem but I can't add the flag lang-all.
                                          Insert CONFIG += lang-all in .pro file has no effect.
