Big thanks for this guide! This is one of only available guides about this that I managed to find. I was able to compile Qt for Orange Pi 4 lts. I used linaro for aarch64-gnu-linux instead since my computer has 64 bit CPU unlike raspberry pi in this video. I also had to create my own device configuration in qtbase/mkspecs/devices/ since there are no configurations for orangepi, but it was pretty easy. I also used Qt 5.15.2 instead because the project I was porting used this version. For some reason, qtwebengine wasn't compiling due to some missing libraries, so I had to -skip it during configuration, but I don't think Ill need it.
Thank you so much for the detailed steps! Before your tutorials I have tried many times and all failed. Follow your tutorials, I got Qt working in my raspberrypi.
Thank you so much for your feedback and this detailed video. I tried this sequence on VM again. then it finally worked. I still do not know the difference between a real machine I tried previously and VM. But, After installing the Ubuntu in the real-machine, I upgraded applications and more by directly downloading from the UI right after the OS installation, not from the terminal. So, I guess something seems to have been changed the system environment in the real-machine. Again, I really appreciate your great tutorial. will be a big fan of yours. :)
thank you sir great video i cross compiled 5.14.2 on ubuntu 20.4 it work's i had to install clang echo the path export LLVM_INSTALL_DIR=/usr/lib/llvm-10 i used wired connection for that : go to network connection and set IPv4 (Checked shared other computers) host #nmap 10.42.0..255/0 (my pi 10.42.0.28) install putty x11 enable X11 forwarding save to pi1 pi #: install vncserver #install xtightvncviewer #vncserver (rasberrypi:1) #xtightvncviewer (in host enter rasberrypi:1 and password and enjoy) my advice to my youtube friends is 1) make copy of the folder before compileing 2) if any think goes wrong delete build folder and sysroot folder 3)please remember do not compile in qtpi folder thank you for all manjunath
Sure would be nice if you could do this with the Microsoft 10 OS. Other words cross compile from windows 10 to RPI4 using the official RPI4 OS of the time. I've done it with Linux a few years ago, and seems that many tutorials want you to use a VM. Not my way of doing things. Please consider and help, probably would be a benefit to many!
Thank you for the detailed steps. I am following your tutorial and while trying to run build script, getting following error "ERROR: Cannot compile a minimal program. The toolchain or QMakeSpec is broken." any ideas what should i do ?

Hey Ulas ! Nice tuto! I have some question or poblem, I hope you have some advices. I have a project with guis and widgets. I can build it on windows and I can run it on windows fine. However the main goal is run on RPI3 or RPI4. I would like to compile the qmake on wsl 64 bit, then build my project without rsync back the qt5pi folder to rpi /usr/local. So many pages tell me this is an important step. How does it possible? I guess the configure needs some extra params. If I build directly on RPI the binary and move the binary to another "virgin" rpi it can run nicely. However after cross compiling there is always some QT_QPA problems with libqxcb or eglfs. I guess I have to statically add all gui libs (GLES, EGL, xcb, etc... ) But I have no idea how to do that... Thanks in advance

Hi Ulas, Thank you for this great guide, I can confirm the new version it also works for RPI3B+[debug and deploy], the only thing that I've struggling is @ the time of writing an app even the hello world, the CLANG parser tool is not working properly, because if I activate the CLANG plugin, it shows me in the code editor the following function called from X or Y library is not being read it or detected, for example: unknown type name 'QCoreApplication' it throws this error when I use anything from the QCoreApplication library, and this repeats with all the QT std libraries. In your video I don't see you get that error, I mean I can compile run, debug everything without problems, but every time I call any instance from QT libraries, it shows me those errors, so in order to rip of those strings errors from the CLANG parser(plugin), what I have done is I have deactivate the CLANG Plugin and that temporary fix the error, but in exchange If I misspell something then It will not be highlighted while I'm typing code, and it will only catch there is an misspelling error only at the compile time, can you help me with this please. Thanks.
For rsync fault : Your Raspberry Pi's pi user must either be granted root privileges, or you can set a root password and then configure the sshd_config file by setting PermitRootLogin yes.
Thank you Ulas Dikme for wonderful work Its working well for me.Can you please guide what we have to do if we want to include any library to work with with this Qt like if we want to include for example libusb or qtZint(bar code generator) or any other libraries in our Qtcreator. Where we have to place their source code and how to cross compile them to be made available for raspberry pi4.
at all this is great work! but when I reach 9.36 when I write "sudo apt-get build-dep qt5-qmake " the OS asked to put some source URIs in the sources list how can I fix this .
Where is the link to all the installed packages and build dependencies? There isn't a link in the description for this. Thanks for the video though! Very helpful.
Hello, when I want to run a project with SSH connection, I get the following error line. qt.qpa.plugin: Could not find the Qt platform plugin "eglfs" in "" This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: linuxfb, minimal, offscreen, vnc, webgl, xcb. Aborted Do you have anything to say about this error?
Great question. I will prepare another content for it. Basically steps will be quite same. I think you do not have to worry about the egl libs. if you call conf file of the rasp then it will be ok. You can try.
Thanks for the video!!! However, I ran into two problems: 1) the make install spit out some error on geoservice and location related. 2) I ran out from virtual machine disc space. any clue?

Hi Ulas. Your video guide is very complete and clear. I'm stuck in a problem. I've managed to successfully compile qt, deploy a test program and your example but when I try to start editing the forms in the designer, the tab with QML Types is all white (empty) and there is a warning sign in the navigator tab besides "page" and "label" elements already inserted by the wizard that says "Item could not be created". It actually seems that you had errors as well when you create the empty project or open your example. I already tried to add qml path to .pro file in "QML_IMPORT_PATH" and "QML_DESIGNER_IMPORT_PATH" but then the designer crash with a message "Line 1: Qt Quick emulation layer crashed". Please help!!
I finally solve my problem by not installing the QtCreator from the Terminal (sudo apt install qtcreator) but from the .run file downloaded from the Qt website. Then everything worked fine. Thanks!

Hi, If you copy the related so files of the opencv to your vm then you can link to the project. th-cam.com/video/2yzvaHcUgEo/w-d-xo.html here I use wiring pi library for cross compilation.

Any advice?
Anyone had luck with 64 bit bullseye release, looking to build everything including QWebengine, almost there.. Hung on crt.o stuff .. needing a good mkspec/device ..
Thank you. Generally a good tutorial with lots of info! But for whatever reason my compiled "qmake" file is 64-bit and not 32-bit so I cannot run it on the Raspi. There might went something wrong with the symbol links.
Okay, I made a mistake and was able to fix it. I started qtcreator on the RasPi and not on the Ubuntu VM. That was the problem. Running fine now on Ubuntu. Build and make is working fine and I get my 32-bit binary for the Pi. Thanks Ulas!

Hello, I did not try for rpi3. There is no hardware dependency for this as I know. At least it can work over x11. You can try it. Also it is a good idea to watch my old video about compiling Qt. It was for old raspberry pi boards. You can find the link below the video.
First: Thank you so much. Next: There are 27 hits for "rsync" in the comments because of errors in your test file. I was able to solve by first creating the directories in sysroot AND adding a "/" after the path of the source (without the quotes). There seems to be no need for the --rsync-path. Hope this helps people.. Otherwise it only seems to setup a link..
Also: rsync -avz --rsync-path="sudo rsync" pi@192.168.16.25:/usr/lib sysroot/usr is putting /lib into /usr messing things up.. needs to end in /lib/usr for destination, no?
My changes (in both use cases). Make directories first. This is all related to a change in behavior in rsync it seems. Note slashes and directories in destination. rsync -avz --rsync-path="sudo rsync" pi@192.168.x.xxx:/lib/ sysroot/lib rsync -avz --rsync-path="sudo rsync" pi@192.168.x.xxx:/usr/include/ sysroot/usr/include rsync -avz --rsync-path="sudo rsync" pi@192.168.x.xxx:/lib/ sysroot/lib rsync -avz --rsync-path="sudo rsync" pi@192.168.x.xxx:/usr/lib/ sysroot/usr/lib rsync -avz --rsync-path="sudo rsync" pi@192.168.x.xxx:/opt/vc/ sysroot/opt/vc

Big thanks for this guide! This is one of only available guides about this that I managed to find. I was able to compile Qt for Orange Pi 4 lts. I used linaro for aarch64-gnu-linux instead since my computer has 64 bit CPU unlike raspberry pi in this video. I also had to create my own device configuration in qtbase/mkspecs/devices/ since there are no configurations for orangepi, but it was pretty easy. I also used Qt 5.15.2 instead because the project I was porting used this version. For some reason, qtwebengine wasn't compiling due to some missing libraries, so I had to -skip it during configuration, but I don't think Ill need it.
The guide works perfect with Ubuntu 20.04 LTS, Pi OS 10, QT 5.12.8! Thanks a lot!
I added only "mkdir sysroot sysroot/usr sysroot/opt" before rsync
Thank you so much for the detailed steps! Before your tutorials I have tried many times and all failed. Follow your tutorials, I got Qt working in my raspberrypi.
This worked perfectly. Thanks for posting! This was quite a bit more involved than I had expected it would be.
i realize it is quite off topic but do anyone know a good site to stream new movies online?
@Henrik Kendrick i watch on flixzone. Just google for it =)
You are the GOAT! Thank you very much!!!!
Thank you so much for your feedback and this detailed video. I tried this sequence on VM again. then it finally worked. I still do not know the difference between a real machine I tried previously and VM. But, After installing the Ubuntu in the real-machine, I upgraded applications and more by directly downloading from the UI right after the OS installation, not from the terminal. So, I guess something seems to have been changed the system environment in the real-machine.
Again, I really appreciate your great tutorial. will be a big fan of yours. :)

Sure would be nice if you could do this with the Microsoft 10 OS. Other words cross compile from windows 10 to RPI4 using the official RPI4 OS of the time.
I've done it with Linux a few years ago, and seems that many tutorials want you to use a VM. Not my way of doing things. Please consider and help, probably would be a benefit to many!
I published new tutorial about how to cross compile with docker. Isolation is good. Maybe it can help. Check my last video.!
Thank you for the detailed steps. I am following your tutorial and while trying to run build script, getting following error "ERROR: Cannot compile a minimal program. The toolchain or QMakeSpec is broken." any ideas what should i do ?
i can't find the /opt/vc/ directory in my raspberry, and i couldnt also build it from source, what should i do ?
Is same steps/process applicable for Raspberry Pi 3 B+ model? If not, what changes need to do?
Yes they are. But I used device "linux-rasp-pi-g++"
Thanks a lot!
Is there a way to compile ARM RasberryPi binaries from Windows?

Hey Ulas ! Nice tuto! I have some question or poblem, I hope you have some advices. I have a project with guis and widgets. I can build it on windows and I can run it on windows fine. However the main goal is run on RPI3 or RPI4. I would like to compile the qmake on wsl 64 bit, then build my project without rsync back the qt5pi folder to rpi /usr/local. So many pages tell me this is an important step. How does it possible? I guess the configure needs some extra params. If I build directly on RPI the binary and move the binary to another "virgin" rpi it can run nicely. However after cross compiling there is always some QT_QPA problems with libqxcb or eglfs. I guess I have to statically add all gui libs (GLES, EGL, xcb, etc... ) But I have no idea how to do that... Thanks in advance
how to build in bullseye ?

Hi Ulas, Thank you for this great guide, I can confirm the new version it also works for RPI3B+[debug and deploy], the only thing that I've struggling is @ the time of writing an app even the hello world, the CLANG parser tool is not working properly, because if I activate the CLANG plugin, it shows me in the code editor the following function called from X or Y library is not being read it or detected, for example: unknown type name 'QCoreApplication' it throws this error when I use anything from the QCoreApplication library, and this repeats with all the QT std libraries. In your video I don't see you get that error, I mean I can compile run, debug everything without problems, but every time I call any instance from QT libraries, it shows me those errors, so in order to rip of those strings errors from the CLANG parser(plugin), what I have done is I have deactivate the CLANG Plugin and that temporary fix the error, but in exchange If I misspell something then It will not be highlighted while I'm typing code, and it will only catch there is an misspelling error only at the compile time, can you help me with this please. Thanks.

Hi Ulas. Your video guide is very complete and clear. I'm stuck in a problem. I've managed to successfully compile qt, deploy a test program and your example but when I try to start editing the forms in the designer, the tab with QML Types is all white (empty) and there is a warning sign in the navigator tab besides "page" and "label" elements already inserted by the wizard that says "Item could not be created". It actually seems that you had errors as well when you create the empty project or open your example. I already tried to add qml path to .pro file in "QML_IMPORT_PATH" and "QML_DESIGNER_IMPORT_PATH" but then the designer crash with a message "Line 1: Qt Quick emulation layer crashed". Please help!!
I finally solve my problem by not installing the QtCreator from the Terminal (sudo apt install qtcreator) but from the .run file downloaded from the Qt website. Then everything worked fine. Thanks!

Hi Ulas, I am looking to use OpenCV with Qt, I was wonder how best to combine them. I have OpenCV 4.3.0 built from source on the Pi4. Thanks again.
Hi, If you copy the related so files of the opencv to your vm then you can link to the project. th-cam.com/video/2yzvaHcUgEo/w-d-xo.html here I use wiring pi library for cross compilation. This maybe can help you. ( But this is not best practice :) ) just check it. If you have any questions please let me know.
here www.raspberrypi.org/forums/viewtopic.php?t=180925
g++ -o test test.cpp -lopencv_highgui -lopencv_core
these two -lopencv_highgui -lopencv_core -> you should copy to your vm to compile your code crossly.
Thanks for that I get the idea, I will try that and let you know thanks.
Ulas Dikme Hi, I scp the two files to my VM and linked in Qt as you did in the video, but when I give the include prompt in main.cpp there are no flags for OpenCV. Not sure what I am missing, thanks again for your video it was very helpful.

I have a Raspberry Pi 4 Model B Rev 1.4 and I am using Ubuntu 20.04 running in VirtualBox on a Windows 10 machine.
I have been following the steps presented in the video.
@24.20, when Ulas issues the command: rsync -avz --rsync-path="sudo rsync" pi@192.168.1.237:/lib sysroot
His host machine receives a number of files -- in the video I can see the contents of lib/firmware, lib/modules.bak, lib/modules, lib/udev
However, when I issue the same command, I only receive a symbolic link
receiving incremental file list
lib -> usr/lib
BTW, a symbolic link is also what I see on the RPi

On a side note, directory usr/bin is almost 3GB
Why am I not copying any files? Any advice?
Anyone had luck with 64 bit bullseye release, looking to build everything including QWebengine, almost there.. Hung on crt.o stuff .. needing a good mkspec/device ..
Thank you. Generally a good tutorial with lots of info!
But for whatever reason my compiled "qmake" file is 64-bit and not 32-bit so I cannot run it on the Raspi. There might went something wrong with the symbol links.
What do you mean 32 bit qmake file ? Could you please share command line output ?
Okay, I made a mistake and was able to fix it. I started qtcreator on the RasPi and not on the Ubuntu VM. That was the problem. Running fine now on Ubuntu. Build and make is working fine and I get my 32-bit binary for the Pi. Thanks Ulas!

Great video! I was wondering if this is possible when implementing Qt with python instead.
Hi Just wondering would this work for pi3 model ? thanks
Hello, I did not try for rpi3. There is no hardware dependency for this as I know. At least it can work over x11. You can try it. Also it is a good idea to watch my old video about compiling Qt. It was for old raspberry pi boards. You can find the link below the video.
First: Thank you so much. Next: There are 27 hits for "rsync" in the comments because of errors in your test file. I was able to solve by first creating the directories in sysroot AND adding a "/" after the path of the source (without the quotes). There seems to be no need for the --rsync-path. Hope this helps people.. Otherwise it only seems to setup a link..
Also: rsync -avz --rsync-path="sudo rsync" pi@192.168.16.25:/usr/lib sysroot/usr is putting /lib into /usr messing things up.. needs to end in /lib/usr for destination, no?
Sorry.. it does require --rsync-path="sudo rsync"
My changes (in both use cases). Make directories first. This is all related to a change in behavior in rsync it seems. Note slashes and directories in destination.
rsync -avz --rsync-path="sudo rsync" pi@192.168.x.xxx:/lib/ sysroot/lib
