      @Ram_Thakkar77 It is clear from the screen-shot that you are not exporting the correct library path. Also ldd would have already shown the error and you would have noticed it.

        @Ram_Thakkar77 So, you put all libs in lib subdirectory?
        Then you need to change the script: LD_LIBRARY_PATH must contain the directory where the libs are.

        LD_LIBRARY_PATH=$dirname/lib
        

        Also, why is Makefile there? It is only needed to build the software.

            @Ram_Thakkar77 Copy symbolic links as well, like: libQt5WebEngineWidgets.so.5, which points to libQt5WebEngineWidgets.so.5.7.1. Your app links against libQt5WebEngineWidgets.so.5 not directly against libQt5WebEngineWidgets.so.5.7.1, so you need those links (as alternative you can rename the libs like: libQt5WebEngineWidgets.so.5 --> libQt5WebEngineWidgets.so.5.7.1).

              @jsulm, you are the savior for me. I pasted all .so files in same directory. Now its not giving error which i was getting previously. I m getting some new error like:

              /root/Desktop/QTEXETesting/QTBrowser: /usr/lib/x86_64-linux-gnu/libQt5Quick.so.5: no version information available (required by /root/Desktop/QTEXETesting/libQt5WebEngineWidgets.so.5)
              
              

              and here is the link for screen shot of same : Screen Shot

                @Ram_Thakkar77 You did not copy all needed libraries! For example libQt5Core.so.5.7.1 is missing: you only have the link libQt5Core.so.5. Please make sure you really have all libs and symbolic links there.

                  I still have doubt if library path is set correctly because the system is referring to libraries in /usr/lib where as it should have been the new path.

                    @p3c0 You're right! I didn't notice this.
                    @Ram_Thakkar77 in the screen-shot you posted you can see that the system tries to load Qt libs from /usr/lib. Check your script, put

                    echo $LD_LIBRARY_PATH
                    

                    after export LD_LIBRARY_PATH and post its output.

                        @Ram_Thakkar77 Please put missing libs (not only links!) in the directory as I said before. For example:

                        libQt5Core.so.5
                        libQt5Core.so.5.7.1

                          @Ram_Thakkar77 Can you do this simple test?

                          • From terminal navigate to the directory where the app binary and libraries are present
                          • export LD_LIBRARY_PATH=/root/Desktop/QTEXETesting:$LD_LIBRARY_PATH
                          • run binary as ./QTBrowser

                          Post the output if you get any errors.

                            @p3c0 I think his problem is that some libs are missing in the directory like QtCore (he has only link there).

                                @Ram_Thakkar77 Plug-ins are missing. From the link I posted before:
                                "When looking for plugins, the application searches in a plugins subdirectory inside the directory of the application executable"
                                Did you create "plugins" subdirectory" and put needed plugins (like xcb) there?

                                    @Ram_Thakkar77 Well, you have to. Qt plug-ins are in "plugins" subdirectory of you Qt installation.

                                        @Ram_Thakkar77 No need to copy the whole plugin folder from Qt!
                                        Create empty plugins subdirectory and put libqxcb.so from plugins/platforms of your Qt installation there.

                                          @jsulm, i didnt found any libqxcb.so file in QT installation path. I found only libqxcb.so file and pasted in plugin folder but getting same error.

                                          @jsulm sorry libqxcb.so i found but its giving me same error.
