How to build Qt for Raspberry Pi3
-
Hi yes I installed these on the Pi in addition to the packages listed in
https://github.com/Kukkimonsuta/rpi-buildqt
RPi Install ninja on Rpi & resync
Rpi Install ruby on Rpi & resync
Rpi Installed Libxss
Rpi Installed Ninja-build
RPI installed gperfwhen I build per aktay's recommendation I get an error in qmake step:
using python: /usr/bin/python version: 2.7.12 Using extra options found in /home/syoung/raspi/src/qtwebengine/src/core/qmake_extras.gypi Using extra options found in /home/syoung/raspi/src/qtwebengine/src/core/qtwebengine_extras.gypi Using extra options found in /home/syoung/raspi/src/qtwebengine/src/core/qmake_extras.gypi Using extra options found in /home/syoung/raspi/src/qtwebengine/src/core/qtwebengine_extras.gypi Updating projects from gyp files... gyp: name 'arm_thumb' is not defined while evaluating condition 'arm_thumb==1' in /home/syoung/raspi/src/qtwebengine/src/core/resources/resources.gyp gyp: name 'arm_thumb' is not defined while evaluating condition 'arm_thumb==1' in /home/syoung/raspi/src/qtwebengine/src/core/core_generated.gyp Project ERROR: -- running gyp_qtwebengine failed --FYI: This is the config summary from the qmake step from aktay:

Just run 'make'. Once everything is built, Qt is installed. You should NOT run 'make install'. Note that this build cannot be deployed to other machines or devices`` Thanks to everyone. -

You can review the below guide.

I believe this is finally solved although it was an arduous process.
-
Started with fresh Ubuntu16 LTS and fresh Jessie Lite
-
Followed Aktays instructions to manually build qtwebengine. Each time it failed, tried to determine missing dependencies. This is what is needed on the VM in addition to those listed in Kukkimonsuta/rpi-buildqt : gperf, bison, flex, gcc-mulitlib, g++ mulitlib, libx32gcc-4.8-dev.
Thanks to everyone who helped!

@sly110
What did you do that actually solved the "gyp: name 'arm_thumb' is not defined" error?Is this actually linked to missing dependencies on the host or target?
I've been trying to cross-compile Qt 5.8 for my RPi3 many different ways now, including the steps mentioned here, but I always end up with this error when it tries to compile qtwebengine.
-

I am also trying to crosscompile qt in raspberry pi 2 for the past weeks following the
https://www.ics.com/blog/configuring-qt-creator-raspberry-pi
https://wiki.qt.io/RaspberryPi2EGLFS
. I configured it without any errors. When i am running a console application the output is getting displayed on the raspberry pi but when i am trying to debug a widget application i am getting this displayed in my qt creator.
Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.Could not load shared library symbols for 22 libraries, e.g. /usr/lib/arm-linux-gnueabihf/libarmmem.so.
Use the "info sharedlibrary" command to see the complete listing.
Do you need "set solib-search-path" or "set sysroot"?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 in this?
thanks in advance -
Hi amruz,
the build of your qt libraries is not in you sysroot. You can either copy qt5pi directory to <your sysroot>/usr/local/ on your development host or tell gdb to load the libraries from your target (see https://forum.qt.io/topic/76928/raspberry-pi-3-debug-info-how-to-fix/38)

Hi amruz,

@sneubert i tried by writing these commands in additional startup commands in qt
set sysroot target:/
but the same warning is coming..
when i am running a console app it is getting displayed in the raspberry without any problems.
but for widget applicationUnable 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).is coming.

ok, my answer was to solve the problem not beeing abel to debug your application:
Unable to find dynamic linker breakpoint function. GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code.Could not load shared library symbols for 22 libraries, e.g. /usr/lib/arm-linux-gnueabihf/libarmmem.so. Use the "info sharedlibrary" command to see the complete listing. Do you need "set solib-search-path" or "set sysroot"?for the remaining message:
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).take a look at previous posts in this forum, e.g.

Work around for arm_thumb error is to be found here
https://github.com/Kukkimonsuta/rpi-buildqt/pull/7Following
https://github.com/Kukkimonsuta/rpi-buildqt/issues/8
I succeeded even in compiling 5.9 (arm_thumb work around was not necessary any more)Both qtwebengine 5.8 and 5.9 work nicely and fast BUT mouse interaction does not work (only keyboard). Anybody had this experience? Very frustrating after all the trouble...
