physicsx / qtonraspberrypi Goto Github PK

Hello,

I get the below when setting up the Pi:

Unable to locate package libboost1.71-all-dev

E: Couldn't find any package by glob 'libboost1.71-all-dev'

E: Couldn't find any package by regex 'libboost1.71-all-dev'

E: Unable to locate package libsrtp0-dev

and in the second batch

E: Unable to locate package libsqlite0-dev

Thanks for the work and vid on this :-)

hello, just working through this guide and ran into issues with the cmake portion.

used the below to install cmake as it said i didn't have it already and didnt understand the git clone bit (total noob)

wget https://github.com/Kitware/CMake/releases/download/v3.22.2/cmake-3.22.2.tar.gz
tar xf cmake-3.22.2.tar.gz
mkdir cbuild && cd cbuild
../cmake-3.22.2/bootstrap --prefix=/opt/cmake --parallel=4 && make -j4 && make install

from https://www.tal.org/tutorials/building-qt-62-raspberry-pi

this failed as I was missing openssh so ran

sudo apt install libssl-dev

this then fixed the issue and cmake installed

I have basically no idea what I am doing so if this is wrong Im sorry, just trying to get it all working so I can struggle bus my way through creating a simple qt application that will take me 6 months when it should take an afternoon.

First off, kudos for the wonderful work! I'm having a hard time cross-compiling Qt6 and PySide6 for Raspberry Pi 4, so this repo REALLY helps me a lot.

I want to ask how you determine which packages are necessary for the custom built RaspberryPi OS. Did you go through the packages files in the official Rpi OS repo and remove unrelated ones, then add the ones required in the Qt official cross-compiling tutorial?

Thank you!

I’m trying to cmake the qt-cross directory. Ive followed the README up to this point successfully but when i run this command.

cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DQT_FEATURE_eglfs_egldevice=ON -DQT_FEATURE_eglfs_gbm=ON -DQT_BUILD_TOOLS_WHEN_CROSSCOMPILING=ON  -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_TESTS=OFF -DQT_HOST_PATH=/home/ubuntu/qt6Host -DCMAKE_STAGING_PREFIX=/home/ubuntu/qt6rpi -DCMAKE_INSTALL_PREFIX=/home/ubuntu/qt6crosspi -DCMAKE_PREFIX_PATH=/home/ubuntu/rpi-sdk/sysroot/usr/lib/ -DCMAKE_TOOLCHAIN_FILE=/home/ubuntu/qt-cross/toolchain.cmake /home/ubuntu/qt-cross/qtbase-everywhere-src-6.6.0/

I get this output/error

-- Configuring incomplete, errors occurred!

I tried adding the lines suggested in #8, this did not change anything as I’m not using that toolchain I’m using the one specified in the readme.

I really enjoyed your video of qt cross-compiling on Raspberry 4!
The environment you created is a little different, but I have Ubuntu OS installed on the Raspberry 4 board, and the source development PC OS is also using ubuntu.
However, the architecture is different, so it seems that cross-compilation is required.
my development pc is amd64 and raspberry is arm64 can you tell me how to cross compile? Are you thinking of creating content?

When i try and execute:

$ sudo apt-get install make build-essential libclang-dev ninja-build gcc git bison
python3 gperf pkg-config libfontconfig1-dev libfreetype6-dev libx11-dev libx11-xcb-dev
libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libxcb-glx0-dev
libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev
libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev
libxcb-util-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev
libatspi2.0-dev libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev

I get the following error (and it is not recommended to change the libc6 version) so is there an other solution to fix this?

I already tried:

update and upgrade

and this

sudo dpkg --configure -a
sudo apt-get -f install

and some more things but they all did not work.

While trying to cross compile raspberry pi I'm getting the following error message
In file included from /home/Raspi/qt6_build/sysroot/usr/include/features.h:485, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/arm-linux-gnueabihf/bits/os_defines.h:39, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/arm-linux-gnueabihf/bits/c++config.h:518, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/bits/stl_algobase.h:59, from /home/Raspi/CrossCompiler/cross-pi-gcc-10.2.0-0/arm-linux-gnueabihf/include/c++/10.2.0/memory:63, from /home/Raspi/qt6_build/qt/build/src/plugins/platformthemes/gtk3/QGtk3ThemePlugin_autogen/EWIEGA46WW/moc_qgtk3dialoghelpers.cpp:9, from /home/Raspi/qt6_build/qt/build/src/plugins/platformthemes/gtk3/QGtk3ThemePlugin_autogen/mocs_compilation.cpp:2: /usr/include/x86_64-linux-gnu/gnu/stubs.h:7:11: fatal error: gnu/stubs-32.h: No such file or directory 7 | # include <gnu/stubs-32.h>
I don't understand why cmake is searching for include files in usr/include/x86_64-linux-gnu/gnu/ even though the cross compiler seems to be configured correctly

I sincerely ask God for help. Thank you.I put my jetson orin through rsync and put /usr and /lib into ~/orin/sysroot under wsl ubuntu, and then cross-compile my application, and an error occurred

I came across an error when executing the following command:

cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DQT_FEATURE_eglfs_egldevice=ON -DQT_FEATURE_eglfs_gbm=ON
-DQT_BUILD_TOOLS_WHEN_CROSSCOMPILING=ON -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_TESTS=OFF

-DCMAKE_TOOLCHAIN_FILE=/home/ulas/qt-cross/toolchain.cmake /home/ulas/qt-cross/qtbase-everywhere-src-6.3.0/

Of course i changed the username.

The error is the following:

ERROR: The OpenGL functionality tests failed! You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2], QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

I am quite new to Linux and have no idea how to fix this. Could you help me ?
I added the output and the error log files. Thanks !

Thank You! I finished the step by step tutorial 。After that，I want to use QT Creator to design the QT project for Rpi4. I need to add QT to QT Versions whitch in QT Creator,I selected ~/qt6rpi/bin/qmake ,it's not working， the raising error is “Qmake Not Executable，The qmake executable /home/yyl/qt6rpi/bin/qmake could not be added.”,I don't know how to fix it. can you help me?

In a few places you have your user name

"cmake -GNinja -DCMAKE_BUILD_TYPE=RelWithDebInfo -DINPUT_opengl=es2 -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=/home/ulas/qt6Host"

unfortunatly, this isnt seen onscreen and easily missed. might be worth making it something that can fail so its easy to figure out for us laymans.

Also, if i want to use QT creator to program, do i need to do anything special to install it after following your guide?

After compilling. I create qtGui. compiling and copy to RPI
but run ./qtGui with error
./qtGui: error while loading shared libraries: libQt6Widgets.so.6: cannot open shared object file: No such file or directory
ldd qtGui
libQt6Widgets.so.6 => not found libQt6Gui.so.6 => not found
file in
/usr/local/qt6rpi/lib/libQt6Widgets.so.6
/usr/local/qt6rpi/lib/libQt6Gui.so.6
