    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.

              Hi,

              Still the same error.
              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’
              g++: error: unrecognized command line option ‘-Wdate-time’

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

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 You're version of g++ is a bit outdated in that regards so you'll have to modify the mkspec a bit to remove the date-time warning as well as change the c++1z with something a little older like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

                          @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.

                                  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.

                                    Hello,

                                    now i am facing one more issue, when i try to compile the program using Qt creator,
                                    getting the below mentioned errors,

                                    home/user/Qt5.8.0/5.8/gcc_64/mkspecs/features/qt_plugin.prf:52: Cannot write file /mkspecs/modules-inst/qt_plugin_qtvirtualkeyboardplugin.pri: Cannot create parent directory
                                    17:58:18: The process "/home/user/Qt5.8.0/5.8/gcc_64/bin/qmake" exited with code 3.
                                    Error while building/deploying project virtualkeyboard (kit: Desktop Qt 5.8.0 GCC 64bit)
                                    The kit Desktop Qt 5.8.0 GCC 64bit has configuration issues which might be the root cause for this problem.
                                    When executing step "qmake".

                                    But the kit is configured and rest of the programs are running, only the virtualkeyboard program is giving me this error...

                                    Guidance is required,

                                    Thanks,

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

                                      Cannot write file /mkspecs/modules-inst/qt_plugin_qtvirtualkeyboardplugin.pri

                                      Are you really trying to write to /mkspects ? This would be a subdirectory of the root directory where a normal user has no write access. Does this directory even exist?

                                        Nope i dnt know regarding that as i was trying to compile the qtvirtualkeyboard program in ubuntu, i am getting the error, but i didnt find the compiling error in windows, strange.

                                        is their any other configuration to be done.

                                        Thanks,

                                          Can you show your .pro file ?

                                          Again, did you start using out of source builds ?
                                          Between two tries, did you nuke the build folder ? If so, how did you nuke it ?
