    Still that doesn't answer my question: since the target is running OpenSuse, why don't you use the package manager ?

        It's nothing Qt specific. So let's start again:

        • list item What exactly is your target ? Computer ? Embedded board ? etc.
        • What processor does it use ?
          * What exact OS is it running ?

            To be able to help you, you should start by first answering my questions.

            Not knowing what you are running on your board I can't answer.

                          hi all. i have the same problem.
                          What exactly is your target ? i wrote a simple Qt program for mini2440 friendly arm. Embedded boar linux gnu.
                          when i execute my program ( and comment running Qtopia) it show me this error : /armNEW: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory
                          i search and find this file in /usr/local/trolltech/qtEmbedded/.... so why i have error?
                          now what can i do now?

                            Hi,
                            /usr/local/trolltech/qtEmbedded/ is a non standard path and probably not the same you have on your computer when cross-compiling your application.

                            You can use LD_LIBRARY_PATH to add that path for the loader to search before starting your application.

                              Hi @SGaist , I am building qt application for an arm embedded target.I have successfully transferred the project files via scp using qt creator. However, the application outputs this error:
                              error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory
                              How can I ensure I have the said library on my target?Is it something I need to cross-compile?
                              I have libQtGuiE.so.4 in /usr/lib
                              Thanks.

                                You have a name mismatch. The one you use on your desktop has no E in its name. You should have the same set of libraries on both the desktop and target.

                                  @SGaist Thank you so much.Just a slight clarification, the E stands for qt Embedded or what?
                                  I'll give you feedback if I manage to fix this.

                                    Likely, yes. I remember vaguely that you could put a suffix when configuring Qt 4.

                                      @SGaist Do you have an idea how I can put that suffix during configuration?
                                      I have confirmed I am using the same qt version qt embedded 4.8.7 in both the host cross compilation pc and target. However I am still getting this error during deployment.What could be the issue?How do I resolve this please?

                                        I may have been wrong there and maybe mixed it with -prefix-install.

                                        The most simple is to deploy the libraries you are using for cross-compilation on the device.

                                          I am looking for libQtGui.so.4 so that I actually can get OpenMW working on Twister OS for RPi4. I found the file on github, & put it into the /usr/lib folder, though the program complained that the provided file is ELF Class 64, implying I need ELF Class 32.

                                          Is there a repository where I can find such Qt project files & libraries?
