Dear JKSH,
Thanks for your support.
I installed libqtgstreamer-dev.
But when I run configuration again nothing change.
Does it need any more packages? -
Did you just re-run configure or did you clean up before ?

Dear SGaist,
Thanks for your advice.
I just rerun configuration,
Could you please tell me how to clean up old configuration on Qt5 without git? -
IIRC, it should be
@make confclean@

Dear SGaist
I tried and got error.
After searching on Google, I found that this command is not work with Qt5
Do you have any ideas? -
Are you doing an out of source build ?

I'm doing in qt-everywhere-opensource where I run command configuration.
It got error result, but when I try this command in qtbase it run successfully.
I run configuration again and nothing change.
Gstreamer is not enabled, and no information about it >"< -
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 ?

Dear SGalst,
About Glib, when i run configuration, this information is displayed.
@

collect2: ld returned 1 exit status

@And in configuration table

Glib support ........... no
GStreamer support ...... no
PulseAudio support ..... no

Are you cross-compiling Qt ?

Yes. It's cross-compiling.

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. -

Are there any ideas?

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.

librt.so.1 exist in /lib/arm-linux-gnueabi
I try to search solution in Google and many answer is add " -lrt" but you can see that it exist in my command.This is my complete configure command

@Note : linux-xxx-g++ exist in qt-everywhere.../qtbase/mkspecs/devices/

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