Raspberry Pi 3: debug info, how to fix?

[jsulm]

@JiujiuTong You need debug version of Qt libraries. You can easily build both versions at the same time adding -debug-and-release parameter to configure command.

[JiujiuTong]

@jsulm
do you mean add -debug-and-release option in configure command before install qt ?

[JiujiuTong]

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

@jsulm
do you mean add -debug-and-release option in configure command before install qt ?

i remeber when using native build method , the -debug-and-release option is invalid.
i will try to reconfig qt with this option.

[jsulm]

@JiujiuTong What do you mean by invalid? You need to rebuild Qt with that parameter.

[jsulm]

@JiujiuTong Do you actually want to debug Qt libs? If not then you do not need a debug build and you can just ignore those warnings.

[JiujiuTong]

@jsulm
the configuer output indicate that -debug-and-release has no effect, and only realse version was built, anyway i will use this option with cross complier method to check the result.

[JiujiuTong]

@jsulm
the output with -debug-and-release option:
WARNING: -debug-and-release is not supported outside of Mac OS X.
Qt can be built in release mode with separate debug information, so
-debug-and-release is not necessary anymore

[JiujiuTong]

@jsulm
I do not want to debug Qt libs, just want to debug my project.
is it ok with these warning if i just want to debug my program ?

[jsulm]

@JiujiuTong Yes it is OK. Just build your project in Debug mode.

[JiujiuTong]

@jsulm
well, thank you

[JiujiuTong]

@jsulm
another question:
my host is Centos 7 x64 , should i change`the following :
Go to Options -> Compilers
Add
GCC
Compiler path: ~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++
to
Go to Options -> Compilers
Add
GCC
Compiler path: ~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-g++
in Qt Creator configuration?

[JiujiuTong]

do you know what's wrong with it ? thank you very much!! my project is cross complier project, my host is centos 7 64bit ,my target device is rpi3 following the steps :
http://wiki.qt.io/RaspberryPi2E
the difference is that my QT5.7.1 source code is download form QT not from git, and i run the configure command (./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) under Qt5.7.1 directory not under Qtbase, so i think all modules except webengine are installed. and i configure QT creator with raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/ /arm-linux-gnueabihf-g++
and i skipped the "11. Still on the device, fix the EGL/GLES library nonsense:"
the error informations seems to relative with qtmultimedia and qtthread. i really don't know how to fix with this. please help me,thank you!

[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:
