Facing issues cross-building Qt-everywhere-src-5.13.1 for Beaglebone Black, throwing undefined reference error with libQt5SerialPort.so.5 -- failing build.
-
Hello Community,
I am new to using Qt (and building it).
I have searched on the web and landed at multiple ways of cross-building the Qt src for Beaglebone Black, of multiple versions, but haven't been successful to build any of those.I am following the guide from one of the GitHub pages here.
The configure command has the following issue (no-wayland support) from the terminal log:

Can someone please help with figuring out what is going wrong here?
Thanks a ton.

Hi and welcome to devnet,
Are you sure you have the udev development package for the correct architecture ?

Hi and welcome to devnet,

@SGaist , Thank you for responding back.
I am quite new to Qt and building or using it.
I am trying to setup a cross-compilation scenario on an ubuntu machine to deploy on to BeagleBone Black running "BeagleBoard.org Debian Buster LXQt Image 2022-01-01" image.
So, i am not sure which udev package should i be focusing on?Would really appreciate if you could let me know which udev package do i need to have and for which architecture?
Host Machine:
OS: Ubuntu 20.04.4 LTS 64-bit
Processor: Intel core i5 -
libudev-dev
As for the architecture, you are cross-compiling so the one for your target,

When i run 'sudo apt install libudev-dev', i get the following output:libudev-dev is already the newest version (245.4-4ubuntu3.17).which as far as i can understand is for 'ubuntu' and not the 'arm-linux-gnueabihf-' required for Beaglebone Black (don't know if that's correct!?).
Any suggestion on how to proceed to solve this error?
Thanks.

The usual way is to use the device and install there all the build requirements and then sync things back to build the sysroot.

@SGaist
An 'apt search libudev' after logging into the beaglebone black via SSH gives the following output:libudev-dev/unknown,now 241-7~deb10u8rcnee0~buster+20211022 armhf [installed] libudev development files libudev1/unknown,now 241-7~deb10u8rcnee0~buster+20211022 armhf [installed] libudev shared libraryI believe i have the required libudev installed on the BBB, and also synced back as sysroot (also confirmed by searching 'libudev'' in the sysroot folder in the files app in ubuntu which showed the libudev.so in ''sysroot/lib/arm-linux-gnueabihf') being used in ./configure step.
-
Which version is it ?
-
Then there's something strange going on since it's version 183 that seems to be requested when linking.
Do you have several udev librairies around ?

-
Did you try to do a full clean build ?
-
@SGaist Yes i did, but that didn't help as well.
The same LIBUDEV error was prominent in a clean build as well.If you have succesfully built Qt for cross-compilation to the Beaglebone black, would you be able to share a guide or something about the actual process and exact commands?

Once everything is built, you must run 'make install'. Qt will be installed into '/home/yash/QT5121/sysroot-glibc-linaro-2.23-2018.05-arm-linux-gnueabihf//home/yash/Qt5ForBBB'. Prior to reconfiguration, make sure you remove any leftovers from the previous build.And the below is the end of the sudo make install command:
make[2]: Leaving directory '/home/yash/QT5121/qt-everywhere-src-5.12.1/qttranslations/translations' make[1]: Leaving directory '/home/yash/QT5121/qt-everywhere-src-5.12.1/qttranslations' cd qtdoc/ && ( test -e Makefile || /home/yash/QT5121/qt-everywhere-src-5.12.1/qtbase/bin/qmake -o Makefile /home/yash/QT5121/qt-everywhere-src-5.12.1/qtdoc/qtdoc.pro ) && make -f Makefile install make[1]: Entering directory '/home/yash/QT5121/qt-everywhere-src-5.12.1/qtdoc' cd doc/ && ( test -e Makefile || /home/yash/QT5121/qt-everywhere-src-5.12.1/qtbase/bin/qmake -o Makefile /home/yash/QT5121/qt-everywhere-src-5.12.1/qtdoc/doc/doc.pro ) && make -f Makefile install make[2]: Entering directory '/home/yash/QT5121/qt-everywhere-src-5.12.1/qtdoc/doc' make[2]: Nothing to be done for 'install'. make[2]: Leaving directory '/home/yash/QT5121/qt-everywhere-src-5.12.1/qtdoc/doc' make[1]: Leaving directory '/home/yash/QT5121/qt-everywhere-src-5.12.1/qtdoc'And somehow, following that guide, i can now succesfully use Qt for development for Beaglebone Black (even though there are some issues).
PS: I believe i was facing the since i was using qtcreator with a latest version (and not the version equivalent to the qt-source that was built, as recommended in that guide).
Also, is there any recent guide to build a new qt-source with cross-compilation for beaglebone black?
Thanks.
