Qt6 BeagleBone Black ARMHF Build Issue

kadirtunc

Hello everyone,

I am new in the forum. If I do something wrong please warn me.

I have built Qt5 for beaglebone black armhf the last month in qt5. But now I want to change the version of Qt to 6.6.

I have researched the sources, but all of them are about raspberry pi. But I tried my chance I change the ./configure parameters but it does not worked wither.

1-Qt5 configure arguments :

sudo ./configure -sysroot /home/arge13-ubuntu/Downloads/sysroot-glibc-linaro-2.25-2019.12-arm-linux-gnueabihf -device linux-beagleboard-g++ -device-option CROSS_COMPILE=/home/arge13-ubuntu/Downloads/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5bbb  -no-xcb -qt-zlib -no-opengl -nomake examples -nomake tests -no-kms -no-eglfs -no-xcb -no-accessibility -no-opengl -skip multimedia -no-gui -no-widgets -no-egl -no-openvg -openssl -no-qml-debug -skip multimedia

After this configuration, config.summary is like this.

Building on: linux-g++ (x86_64, CPU features: mmx sse sse2)
Building for: devices/linux-beagleboard-g++ (arm, CPU features: neon)
Target compiler: gcc 7.5.0
Configuration: cross_compile compile_examples enable_new_dtags largefile neon precompile_header shared rpath release c++11 c++14 c++1z concurrent dbus no-pkg-config reduce_exports stl

And it works. I am currently using qt 5.12.1 version for cross compiling. I can deploy my armhf build project to beaglebone via ssh. I can debug it also.

2-Qt6 configure arguments :

Actually it is almost same.

But config.summary is like this:

Building for: devices/linux-beagleboard-g++ (x86_64, CPU features: )
Compiler: gcc 9.4.0

What I have done :
I downloaded qt-everywhere-src-6.6.1
Downlaoded sysroot-glibc-linaro-2.25-2019.12-arm-linux-gnueabihf for sysroot parameter
Downloaded gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf for CROSS_COMPILE parameter.

What am I missing?

Unfornunately I can not pass the arguments from the terminal because of this I must add some parameters to CMakeLists.txt file manually.

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

Qt is now configured for building. Just run 'cmake --build . --parallel'

Once everything is built, you must run 'cmake --install .'
Qt will be installed into '/usr/local/qt6bbb2'

To configure and build other Qt modules, you can use the following convenience script:
        /usr/local/qt6bbb2/bin/qt-configure-module

If reconfiguration fails for some reason, try removing 'CMakeCache.txt' from the build directory

@kadirtunc said in Qt6 BeagleBone Black ARMHF Build Issue:

filesystem: No such file or directory

Is C++17 enabled?

kadirtunc

@jsulm Thanks for reply, I added

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

But it does not worked.

Some forums says it is about the gcc linaro's version. So I installed the ubuntu 22.04 in docker and installed dependencies,

Now it says,

sudo apt install gcc-multilib does not worked.

So I have another question, does crti.o and crti1.o files looking armhf compiled version or x86 compiled version?

And another question, while qt5 cross compile is not hard, why qt6 cross compile is so hard? what am I missing ?

@kadirtunc said in Qt6 BeagleBone Black ARMHF Build Issue:

The version matching the compiler.
Is that compiler installed properly? Can you build a simple C/C++ application using it? Is your sysroot installation correct?

@kadirtunc

I found this info. in your build and like @jsulm states, C++ 17 seems to fail on your build even though it seems you have it.

@kadirtunc said in Qt6 BeagleBone Black ARMHF Build Issue:

-- Performing Test HAVE_cxx17_filesystem - Failed

--   i18n (required)
--   uc (required)
--   data (required)

Thos libs. are required obviously. You might need to install them... Also, I noticed you were using Makefile instead of ninja for your compilation.

Seth

P.S. I am the person trying to help you on StackOverflow. It seems we are discussing two, separate topics. You want to cross-compile and I want you to install the Debian Distro repo versioning. I am sorry. Good luck for now. I will keep trying.

kadirtunc

@silver2row Thank you for reply. Actually when I opened this topic I am still trying to achieve my goal. I am trying now also. I tried different versions of gcc linaro, sysroot and qt >=6.5. I want to use new CanBus classes. It comes with qt6.5. I can not find a tool like python cantools. It can parses and decodes frame and gives the value from value table. Because of this I want to use cross compiling. If there is a guide for building Qt 6.5 or higher for beaglebone black It will be helpful. But I saw your answer in StackOverflow. I still have hope. There must be a way to cross compile.

silver2row

@kadirtunc ,

You are welcome. I was unaware of you using the libraries within Qt6.x for your programming needs. I might have went off on a tangent thinking you could just use whatever Debian Bookworm had offered.

I am sorry. If I configure the build, I will let you know. I may not be able to be of any assistance though, i.e. due to other items of interest I am currently testing.

Hi do you try to cross compile Qt for arm or you build it on you actual device?

Why am I asking?
From what I see you specified the C/CXX compiler and expect Qt is built using it. You should build/use host Qt when cross-compiling to make Qt tools work.

You can take the inspiration from this topic https://wiki.qt.io/Cross-Compile_Qt_6_for_Raspberry_Pi. Scroll to "Building Qt 6" topic. It suggests building Qt6 for host first and then use it by specifying the '-qt-host-path' argument.

Hope this will help you, don't hesitate to ask further questions.
