    If you are using a source package I would say, delete your current sources and start from new.

    Also, use the shadow build possibility, this way you can play with the configuration without cluttering your sources

      Dear SGalst,
      Thanks for a lot of support you give to me.
      Do you mean that I should delete the current qt-everywhere-opensource...
      uncompress file and configuration again ?
      I will try it .
      I have one more question.
      In my Qt configuration information, GLIB is disable,
      If I want to enable Gstreamer, I need to enable GLIB, is it right ? or they don't have any relation ?

      Again, thank you so much!

        Yes, that's what I mean.

        Disabled or not detected ?

            Are you cross-compiling Qt ?

              Yes. It's cross-compiling.

                  That's the kind of detail you should have mention earlier...

                  First thing, did you install a cross-compiling environment ? Did you pass the correct parameters to configure to enable cross-compilation ? Did you get the cross-compiled version of the dependencies you need ?

                    Dear SGalt,
                    Sorry about mention cross-compiling lately.
                    The cross-compiling is installed in my system, it is linaro-arm-linux-
                    About parameters to configure, I think Qt can autodetect Gstreamer so I don't pass any option for Gstreamer in command.
                    When configuration, nomally it will display information why option is disable, which errors occurs... so I can fix errors and option is enable . With Gstreamer, nothing to display, it makes me confusion.
                    Thank for your support.

                        You're configuration process fails while testing glib, do you have it for ARM ? Also can you post your complete configure command ?

                          Dear SGalt,
                          I have just installed glib2.0, libglib2.0, libglib2.0-dev, libqtglib2.0 before.

                            Since you are cross-compiling, you also need to either get the ARM version of these libraries or cross-compile them.

                                    Then how can the configure script find the libraries ?

                                    One way to do that is to copy the libraries and headers from your target rootfs in your toolchain directories

                                      Hello, I know this thread is quite old but I'm running into the same issues. I mounted the target's rootfs in a local folder and I set the sysroot parameter to that path.

                                      In that folder there is the complete arm filesystem with these packages installed:

                                      @
                                      libgstreamer0.10-dev
                                      libgstreamer-plugins-base0.10-dev
                                      gstreamer-tools
                                      gstreamer0.10-plugins-bad
                                      gstreamer0.10-plugins-good
                                      gstreamer0.10-plugins-ugly
                                      libglib2.0-dev
                                      libglib2.0-0
                                      libqtglib-2.0-0
                                      @

                                      Here the configure command:

                                      @
                                      ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/dev/rpi/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-relocations -reduce-exports -release -developer-build -make libs -prefix /usr/local/qt5pi -no-pch -nomake examples -nomake tests -silent

                                      Anyway both GLib and GStreamer supports are disabled. Here the related errors:

                                      But the /mnt/rasp-pi-rootfs/lib/arm-linux-gnueabihf/librt.so.1 is there, actually.

                                      Any ideas?

                                        Dear Mark,
                                        Please check the link to librt.so.1
                                        Maybe it's broken

                                          I cross compile Qt 5.2 for imx6 from source and ./configure just dont try find gstreamer from rootfs. I look at ./configure inside and dont find anything about gstreamer. What can I do?
