Raspberry Pi 3: debug info, how to fix?

@SSGaist
can you help me out of this problem? thank you!
@jsulm
i have check the files , both ligQt5OpenGL.so and libQt5Multimedia.so exists,
and the build output is still:

@JiujiuTong Can you show your configure call?
@jsulm
my configure is :
"./configure -release -opengl es2 -skip webengine -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v "
my host is centos 7 x64, the target is raspberry pi3. thank you ! -

my host is centos 7 x64, the target is raspberry pi3. thank you !@JiujiuTong Does your sysroot contain all that incompatible libraries (like libpthread.so)?
-
@JiujiuTong As I said "skipping incompatible" message means that the library is build for a different architecture. You're most probably mixing architectures.
/usr/lib/libpthread.so - this looks like a path on your host PC. You cannot use libraries from your host PC (X86_64) to cross compile for ARM.@jsulm
can you explain more precise, i'm just following the ways list by:
http://wiki.qt.io/RaspberryPi2EGLFS
should i do something else, if so can you help me ? -

@JiujiuTong Does your sysroot contain all that incompatible libraries (like libpthread.so)?

@jsulm
i just sync from raspberry, is there anyway to check if incompatible libraries are included in that path?@JiujiuTong My question was: does it contain that file?
-
@JiujiuTong My question was: does it contain that file?

@jsulm
yes,there is a libpthread.so -
@jsulm
sorry for my late reply
these days i have been rework the job. just following the steps again.
now there is another error :
/usr/include/math.h:31: error: bits/math-vector.h: No such file or directory
#include <bits/math-vector.h>
i try to find the file bits/math-vector.h ,but there is no such file
and i searched that is should be included in libc6-dev package.
but i have installed the latest package , but still no such file
is there any other ways to fix it? thank you very much ! -

@JiujiuTong How did you configure the kit in QtCreator? If it is set up correctly then it should work.

@jsulm
i think the configure is correct, i am following the steps :
http://wiki.qt.io/RaspberryPi2EGLFS
first create device ,then configure compiler,debug, and Qtversion. Go to Options -> Build & Run with sysroot path selected.
i add the absolute path in the project, then it seem ok now with one problem:
https://forum.qt.io/topic/77854/error-undefined-reference-to-std-__throw_out_of_range_fmt-char-const-glibcxx_3-4-20/3

yes , i try ,but it failed

關於這個錯誤：
/home/tong/raspi/qt5pi/lib/libQt5MultimediaWidgets.so: undefined reference to QGLContext::currentContext()@Qt_5'
....
...我是加入：
.pro:
QT += opengl
才解決此問題的會加 qt += opengl 是因為 QGLContext::currentContext() ...etc 來自於 opengl
我覺得這 error 是因為 Qt5MultimediaWidgets 於 Embedded 時，會去呼叫 opengl 方法的關係希望對你有幫助。

@Levy ,got it , thanks!

I am also getting the error when i try to cross compile qt in raspberry pi 2 without x11.
When i am running console application it is running.
But when i am using widget application in pi touchscreen it is showing
"Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters)."
and the system is idle
can anyone help me with thiswhen i am debugging the output in qtcreator is as follows
Debugging starts
Listening on port 10000
Remote debugging from host 192.168.15.153
Process /home/pi/qtinpitry created; pid = 8079
File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead.
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).can anyone help me.
Thanks in advance
