Raspberry Pi 3: debug info, how to fix?

jsulm · 8 Mar 2017, 13:35

@JiujiuTong Are the libraries there?

JiujiuTong · 3 Aug 2017, 13:42

@jsulm
Qt OpenGL modules? it seems no this module there.
and i rebuild QtMultimedia module, it's no problem
there is no need to install OpenGL in raspberry 3 ,right?
in my host i have install openGL now ,it still doesn't work

JiujiuTong · 9 Mar 2017, 06:55

@jsulm
i can find libQt5MultimediaWidgets.so , but i don't know where to find openGL related files...

jsulm · 9 Mar 2017, 07:46

@JiujiuTong What about libQt5OpenGL.so ?

JiujiuTong · 3 Sept 2017, 07:48

@jsulm
I reconfigure and reinstall the QT,and find the opengl related files in the source qtbase ,
I also find the libQt5OpenGL.so after reinstall. I will retry the project later. thank you for your informs.

@jsulm
i have check the files , both ligQt5OpenGL.so and libQt5Multimedia.so exists,
and the build output is still:

@jsulm ,do you have any ideas? thank you !

jsulm · 16 Mar 2017, 05:39

@JiujiuTong said in Qt on rpi3 , debug info ,how to fix?:

skipping incompatible /usr/lib/libpthread.so

You are linking against x86 libraries installed in your host machine! You need to link against libraries for your target device since you're cross-compiling.

JiujiuTong · 16 Mar 2017, 05:41

@jsulm
my host machine is x64 , i don't kown what to do.
can you tell me how to link it please? i'm following the instructures descripted by :
http://wiki.qt.io/RaspberryPi2EGLFS
can you give me some instructions please!,thank you very much

jsulm · 16 Mar 2017, 05:58

@JiujiuTong How are you building? Can you show your configure call? Does your sysroot contain all needed libraries?

JiujiuTong · 16 Mar 2017, 06:03

@jsulm
i,m using cross compile,and 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

and i sysroot all the directory under raspi with "./sysroot-relativelinks.py sysroot"

jsulm · 16 Mar 2017, 06:06

@JiujiuTong said in Qt on rpi3 , debug info ,how to fix?:

~/raspi/sysroot

Did you check that your sysroot really contains what is needed (for example ~/raspi/sysroot/usr/lib)?

JiujiuTong · 16 Mar 2017, 06:10

@jsulm
i really don't know what libs are needed, so i do not check the Dir, the folder is created by :
mkdir sysroot sysroot/usr sysroot/opt
rsync -avz pi@raspberrypi.local:/lib sysroot
rsync -avz pi@raspberrypi.local:/usr/include sysroot/usr
rsync -avz pi@raspberrypi.local:/usr/lib sysroot/usr
rsync -avz pi@raspberrypi.local:/opt/vc sysroot/opt
and i checked that the output is right with no error.

jsulm · 16 Mar 2017, 06:18

@JiujiuTong Maybe you should try to call configure from a clean Qt source directory? Did you try to build Qt before for x86? Even better would be to do out of source build see http://stackoverflow.com/questions/1245011/how-to-build-qt-out-of-source

JiujiuTong · 16 Mar 2017, 06:20

@jsulm
i confirm the source file is clean ,it is download from QT. i have built the QT under windows and centos x64, but not for x86.

jsulm · wrote on 16 Mar 2017, 06:20

@JiujiuTong What I mean with this "Did you try to build Qt before for x86?" is - did you build for x86 OR x86_64 before from the SAME source code tree? Because currently you're linking against your host libraries.

JiujiuTong · J jsulm 16 Mar 2017, 06:10

@jsulm
and i have tried to start a simple qt application(just a page with nothing showed ). it works well .
the source file is clean every time i try to build the QT, i will delete the source file and extract it from source file.

@crasskitty
sorry , i don't understand what's your meanings

sneubert · 20 Mar 2017, 02:42

I dont´t know if you still have the debugging problem but to answer to your first post:

The qt libraries for rpi are written to the qt5pi directory, outside of the rsynced sysroot.
The debugger is looking in the local sysroot directory for the libraries if you debug remote targets.
So just tell gdb to load the libraries of your project from the debugging target.
In Qt Creator go to Options->Debugger GDB-Tab an insert set sysroot target:/ in "Additional Startup Commands"

JiujiuTong · wrote on 20 Mar 2017, 02:42

@sneubert
thank you for your answer!
should I just insert "set sysroot target:/" in "Additional Startup Commands" or replace string with my ENV value?
I can understand you description, but confused with "set sysroot target:/" i have set sysroot to "/home/tong/rasp/sysroot" in build&run -->kits-->sysroot. should the target:/ be the real path or something? thank you very much!
