Raspberry Pi 3: debug info, how to fix?

[jsulm]

@JiujiuTong It doesn't matter whether the compiler itself is 32bit or 64bit.
Regarding errors: were QtMultimedia and Qt OpenGL modules built?

[JiujiuTong]

@jsulm
do you mean QtMultimedia and Qt OpenGL were not built ?
in qt-everywhere-opensource Qt5.7.1, with "./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 ", i think these module should be built , how to check if these modules were built or not ?

[jsulm]

@JiujiuTong Are the libraries there?

[JiujiuTong]

@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]

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

[jsulm]

@JiujiuTong What about libQt5OpenGL.so ?

[JiujiuTong]

@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.

[JiujiuTong]

@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]

@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]

@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]

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

[JiujiuTong]

@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]

@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]

@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]

@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]

@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]

@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]

@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.

[JiujiuTong]

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